Latest / What's Your Problem? / How to Start 40 Companies (and Counting)
Transcript
- 0:15Speaker 1: Pushkin. You want to start listing off the companies of
- 0:22Speaker 1: which you're a founder and a co founder and stop
- 0:24Speaker 1: wherever you get tired.
- 0:26Speaker 2: I mean I can try to do that, but that
- 0:28Speaker 2: might take some time.
- 0:30Speaker 1: Give me a handful. Count count off five on your fingers,
- 0:33Speaker 1: just for sure.
- 0:34Speaker 2: Sure, well, Maderna Momenta PureTech Seer, living Proof.
- 0:42Speaker 1: For a second thought, you were just going to do
- 0:44Speaker 1: the MS, which might have been.
- 0:45Speaker 2: A while I could, I could do with the aged.
- 0:50Speaker 1: Robert Langer has founded or co founded something like forty companies.
- 0:54Speaker 1: He is an institute professor at MIT. He holds over
- 0:58Speaker 1: a thousand patents, and his research has been cited more
- 1:01Speaker 1: than four hundred thousand times. But when he started his
- 1:06Speaker 1: career in the nineteen seventies, he didn't see bound for
- 1:09Speaker 1: professional glory. He had a hard time finding a job,
- 1:13Speaker 1: he couldn't get funding for his research, and his patent
- 1:16Speaker 1: applications kept getting rejected. And I think these two things,
- 1:21Speaker 1: his early struggles and his later massive success are in
- 1:25Speaker 1: fact closely connected. Langer was trying to do something that
- 1:29Speaker 1: was deeply and profoundly different than what anybody had done before.
- 1:33Speaker 1: Almost nobody understood it. Almost nobody knew what to do
- 1:37Speaker 1: with him, and then when his work finally did succeed,
- 1:41Speaker 1: it was such a new, powerful discovery that people are
- 1:45Speaker 1: still building on it today half a century later. I'm
- 1:54Speaker 1: Jacob Goldstein and this is What's Your Problem, the show
- 1:56Speaker 1: where I talk to people who are trying to make
- 1:59Speaker 1: technological progress. Robert Langer is still working, still doing research,
- 2:04Speaker 1: still founding companies, and we talked about some of his
- 2:07Speaker 1: current work in the later part of our conversation. But
- 2:10Speaker 1: to start, we went back to the mid nineteen seventies
- 2:13Speaker 1: when Langer got his doctorate in chemical engineering and he
- 2:17Speaker 1: did something that at the time was really unusual. He
- 2:21Speaker 1: did a postdoc with a medical school professor, a pediatric
- 2:24Speaker 1: surgeon named Judah Folkman. Langer's field is bioengineering, basically bringing
- 2:30Speaker 1: the tools of engineering to the fields of biology and medicine.
- 2:35Speaker 1: And bioengineering is a huge field today, but it barely
- 2:39Speaker 1: existed back when Langer started his postdoc with that doctor,
- 2:43Speaker 1: Judah Folkman, and bioengineering was exactly what Judah Foalkman needed.
- 2:49Speaker 1: Folkman had an idea for a new kind of drug,
- 2:52Speaker 1: and this kind of drug was a molecule that was
- 2:54Speaker 1: too big and complex to be given as a pill.
- 2:58Speaker 1: So Folkman needed somebody who could figure out how to
- 3:01Speaker 1: deliver this new kind of drug to patience. As you'll hear,
- 3:05Speaker 1: that delivery problem was fundamentally an engineering problem, and when
- 3:10Speaker 1: Langer solved that problem, he created an entirely new way
- 3:14Speaker 1: to get medicine to patients, and it proved incredibly useful.
- 3:22Speaker 1: Tell me about being an engineer and going off to
- 3:24Speaker 1: work in the nineteen seventies in the lab of a physician.
- 3:29Speaker 2: On the one hand, for me, it was very hard
- 3:31Speaker 2: because I had to learn a lot about medical things
- 3:34Speaker 2: and I didn't know very much biology, so that was
- 3:39Speaker 2: that was difficult. But on the other hand, being an engineer,
- 3:43Speaker 2: I guess I had a different perspective, you know that
- 3:46Speaker 2: I didn't maybe think the same way as a clinician
- 3:51Speaker 2: or surgeon or a biologist. You know, engineers they solve problems,
- 3:55Speaker 2: and that Judah Falkman, who was my boss at the time,
- 3:58Speaker 2: I mean, that's what he wanted. He wanted to see
- 4:01Speaker 2: a problem solved.
- 4:02Speaker 1: So let's talk specifically about that problem. What did you
- 4:06Speaker 1: what did you go to doctor Falkman's lab to work on.
- 4:09Speaker 2: Doctor Fokeland had this idea that if you could stop
- 4:12Speaker 2: blood vessels, you could stop cancer. It wasn't most people
- 4:17Speaker 2: didn't think he was right. In fact, he went further.
- 4:20Speaker 2: He said that the reason blood vessels come to the
- 4:24Speaker 2: tumor is that the tumor makes a chemical signal he
- 4:29Speaker 2: called the tumor antigenesis factor, and he said that was
- 4:32Speaker 2: chemically mediated. And also the idea that he thought about
- 4:37Speaker 2: is if that was chemically mediated, maybe stopping it could
- 4:40Speaker 2: also be chemically mediated. So my job really, in a
- 4:45Speaker 2: way was to prove that he was right, because almost
- 4:47Speaker 2: everybody told him he was wrong, and in so doing
- 4:50Speaker 2: isolate the first you know, blood vessel or antiogenesis inhibitor,
- 4:55Speaker 2: uh huh.
- 4:56Speaker 1: And so it's basically that there is this theory that
- 4:59Speaker 1: he had that tumors stimulate the growth of new blood vessels,
- 5:04Speaker 1: and then if that's true, perhaps you could inhibit the
- 5:07Speaker 1: growth of new blood vessels thereby inhibit the growth of tumors. Right,
- 5:13Speaker 1: And so you get there, and I'm interested in that
- 5:17Speaker 1: inhibition piece, right, because that seems like that's where you're really,
- 5:20Speaker 1: in a very direct way, bringing your engineering skills to
- 5:25Speaker 1: bear on this medical problem. So, like, talk about that
- 5:27Speaker 1: side of it and how you approached it.
- 5:30Speaker 2: So what we wanted to do was have a little
- 5:32Speaker 2: nanoparticle or microparticle that could deliver different molecules I was isolating,
- 5:39Speaker 2: and these were fairly large molecules, so that was really
- 5:42Speaker 2: the idea, and then see could it stop the blood vessels?
- 5:45Speaker 1: So this core idea of developing a nanoparticle to deliver
- 5:50Speaker 1: a large molecule basically a complicated drug, is an engineering problem, right,
- 5:56Speaker 1: this nanopart of It's like, we've got this this drug
- 5:59Speaker 1: call it that we think might be able to stop
- 6:01Speaker 1: tumor growth, but how do we get it to the tumor? Right?
- 6:04Speaker 1: That is a basic problem that you were coming up
- 6:07Speaker 1: against early in your research, and that that problem winds
- 6:11Speaker 1: up being a big deal, right, and the way you
- 6:13Speaker 1: go about solving that problem winds up being a big deal.
- 6:16Speaker 1: So tell me about that.
- 6:19Speaker 2: Well, the nanoparticles and microparticles, really it's taking molecules drugs, encapsulating,
- 6:27Speaker 2: surrounding them with a lipid or polymer, and delivering it
- 6:32Speaker 2: to sells or a patient or an animal.
- 6:36Speaker 1: And a lipid or a polymer is basically some fat
- 6:38Speaker 1: or some plastic.
- 6:40Speaker 2: Yeah, yeah, lipid is some fat and polymer some plastic.
- 6:43Speaker 2: Generally speaking, So, yeah, if you escape the drug by
- 6:48Speaker 2: itself and it wasn't packaged in those particles, it would
- 6:51Speaker 2: just get destroyed. I mean, so the number one reason
- 6:56Speaker 2: you do it is to protect it, you know, otherwise
- 6:59Speaker 2: it won't you know, they'll just get destroyed, probably almost immediately.
- 7:03Speaker 2: So you know, we ask people who are experts in
- 7:07Speaker 2: that area, know about price winners and others who had
- 7:10Speaker 2: done work or at least helped on delivery of small molecules,
- 7:16Speaker 2: and we asked them about that, but they all told
- 7:18Speaker 2: us it wasn't possible. So I spent years in the
- 7:22Speaker 2: laboratory experimenting, finding hundreds of different ways, failing hundreds at
- 7:27Speaker 2: different times, but finally I was successful. And you know,
- 7:32Speaker 2: we published a paper in Nature in nineteen seventy six,
- 7:36Speaker 2: the General Nature, and showed for the first time that
- 7:40Speaker 2: you could deliver large molecules this way. And we published
- 7:43Speaker 2: a paper in Science in nineteen seventy six showing for
- 7:46Speaker 2: the first time that you could stop blood vessels by
- 7:49Speaker 2: using approaches like this.
- 7:51Speaker 1: And as I understand it, even after you published those papers,
- 7:55Speaker 1: you met a lot of resistance.
- 7:57Speaker 2: Yeah I did. I suppose I met a lot of
- 8:00Speaker 2: resistance for a couple of ways. First, different people didn't
- 8:04Speaker 2: agree with it or didn't believe it or didn't think
- 8:06Speaker 2: it was possible. Secondly, my background really wasn't right. I
- 8:11Speaker 2: suppose for the different review sections, I was an engineer,
- 8:15Speaker 2: and when we sent the grants to the National Insituites
- 8:20Speaker 2: of Health in places like that, you know, they had
- 8:23Speaker 2: medical people or biological people reviewing it, and they said, well,
- 8:26Speaker 2: what can an engineer, You know, he doesn't know anything
- 8:28Speaker 2: about biology or oncology. Separately, I met a lot of
- 8:33Speaker 2: resistance when I tried to do this get a job
- 8:36Speaker 2: in an engineering department. They said, well, engineers a chemical
- 8:40Speaker 2: engineering department, They said, engineers really don't do experimental biology.
- 8:44Speaker 2: So I didn't get any faculty positions in a chemical
- 8:48Speaker 2: engineering department for a very very long time. I ended
- 8:51Speaker 2: up in an fishing department.
- 8:52Speaker 1: And so, I mean, this idea of bioengineering that is
- 8:57Speaker 1: a big deal now and was very novel. Then it
- 9:00Speaker 1: feels like you're sort of coming up against this problem
- 9:02Speaker 1: of creating a field that doesn't quite exist yet, or
- 9:06Speaker 1: at least creating a part of a field that doesn't
- 9:08Speaker 1: exist yet, which seems like, on the one hand, the
- 9:10Speaker 1: opportunity to solve very large problems was clearly there. On
- 9:13Speaker 1: the other hand, the kind of institutional structure to allow
- 9:16Speaker 1: that to happen was was not on your side.
- 9:19Speaker 2: Yeah, you're right. I mean, Ei there had been people
- 9:22Speaker 2: in chemical engineering doing work on what i'd call mathematical modeling,
- 9:27Speaker 2: you know, transport of molecules, but experimental stuff, inventing things. Yeah,
- 9:31Speaker 2: that and discovering you know, new molecules that certainly had
- 9:36Speaker 2: not been done, never been done in chemical engineering up
- 9:40Speaker 2: till that time. So so that ended up being hard.
- 9:46Speaker 1: Is it right that some of your early patent applications
- 9:48Speaker 1: around this technology were also rejected?
- 9:51Speaker 2: Yeah they were. I mean the first the main patent
- 9:55Speaker 2: on it got rejected five times in a row. But
- 9:59Speaker 2: you know, sometimes that happens. I'vet after that. I think
- 10:03Speaker 2: I had one when we came up with the idea
- 10:05Speaker 2: of tissue engineering. I think that got rejected even more.
- 10:08Speaker 2: So those things happen.
- 10:10Speaker 1: And so you get the patents and you end up
- 10:13Speaker 1: licensing the technology initially to one or more big big companies, right,
- 10:18Speaker 1: big pharmaceutical company. What happens with that?
- 10:21Speaker 2: Yeah, well, actually the hospital did that the license because
- 10:24Speaker 2: I mean, the past is my name, but they licensed it,
- 10:27Speaker 2: you know. I well, I was very excited about that.
- 10:30Speaker 2: There were two multi billion dollar companies won an animal
- 10:34Speaker 2: health one in human health. You know, So they they
- 10:37Speaker 2: gave me a consulting fee. They gave me actually a
- 10:40Speaker 2: very large grant, which for young professors, you know, terrific.
- 10:44Speaker 2: Most importantly, they were going to work on it, and
- 10:46Speaker 2: they did work on it for maybe up to a year,
- 10:49Speaker 2: but then they just gave up. So I got the
- 10:52Speaker 2: grant and the consulting fee, but I didn't get what
- 10:54Speaker 2: I wanted most, which was to see the work that
- 10:57Speaker 2: we did make a difference in the world.
- 10:59Speaker 1: Were you surprised when they gave up? What was your
- 11:01Speaker 1: response when they gave up?
- 11:03Speaker 2: I guess I was sad. I don't know that I
- 11:05Speaker 2: was surprised. I certainly have seen plenty of places give
- 11:09Speaker 2: up before, but it made me sad. I really thought
- 11:12Speaker 2: that this was a way of moving things forward, was
- 11:17Speaker 2: having companies, you know, take what you published and what
- 11:21Speaker 2: you did and develop it. But I was mostly sad.
- 11:25Speaker 1: So how do you get from there to starting your
- 11:27Speaker 1: first company?
- 11:29Speaker 2: Yeah? Well, a good friend of mine, Alex kleebman Off,
- 11:31Speaker 2: he was a professor in that nutrition department lady. He
- 11:35Speaker 2: was a professor in the chemistry department and mit he
- 11:39Speaker 2: said to me one day after this happened, he said, well, Bob,
- 11:42Speaker 2: we should start our own company. So I thought, yeah,
- 11:46Speaker 2: if you're not your own champion, nobody else is going
- 11:48Speaker 2: to be. So we did, and I got a number
- 11:52Speaker 2: of my students to join that company, and they were
- 11:55Speaker 2: very excited about it, so that that ended up. You know,
- 11:59Speaker 2: they weren't going to give up very easily.
- 12:02Speaker 1: And so you keep working on this original idea of
- 12:06Speaker 1: a particle that can deliver a drug, a large molecule
- 12:10Speaker 1: drug basically, and when does it become clear to you
- 12:15Speaker 1: that it's going to work.
- 12:17Speaker 2: Well, actually, for me, I was pretty clear it was
- 12:20Speaker 2: going to work when we wrote that.
- 12:21Speaker 1: Early paper in Nature.
- 12:23Speaker 2: I mean I thought i'd see it with my own eyes.
- 12:25Speaker 2: I put certain types of well I'm trying to think,
- 12:28Speaker 2: I explained. I put certain enzymes. Those are all large
- 12:31Speaker 2: molecules in these materials, and I had this test that
- 12:36Speaker 2: would turn color if the enzymes are coming out, and
- 12:40Speaker 2: I've got to see it not work many many, many times,
- 12:43Speaker 2: hundreds of times. But finally I did see it work,
- 12:46Speaker 2: and so I didn't see how this couldn't you know,
- 12:51Speaker 2: so since I saw it with my own eyes, but
- 12:53Speaker 2: that didn't mean that other people were going to necessarily
- 12:56Speaker 2: believe it. But I did, and you know I had
- 13:00Speaker 2: people still ten fifteen years later tell me couldn't possibly
- 13:04Speaker 2: be right. I mean, very experienced people. But you know
- 13:08Speaker 2: that's the world. I mean a lot of times they're skepticism.
- 13:11Speaker 1: And what was the first drug from that idea that
- 13:15Speaker 1: made it to the market, that made it to patients.
- 13:19Speaker 2: You know, we had this collaboration with a company called
- 13:22Speaker 2: Taketa as a Japanese company, and they had sent people
- 13:26Speaker 2: to our lab every year and we got a grants
- 13:28Speaker 2: from them, and they created what's called lupron depot and
- 13:33Speaker 2: that was that ultimately did get approved and still versions
- 13:39Speaker 2: of it are widely used today.
- 13:41Speaker 1: What kind of patients did that treat? What did that
- 13:43Speaker 1: drug do?
- 13:44Speaker 2: It was a way to treat advanced prostate cancer and endometriosis.
- 13:48Speaker 1: And was it the anti angiogenesis? Was it inhibiting the
- 13:51Speaker 1: formation of blood vessels or was it.
- 13:53Speaker 2: Something you no, No, it was it was affecting hormones.
- 13:56Speaker 2: It was a different hormonal thing, the antiogenesis ones that
- 14:01Speaker 2: there you know, other people used the essays we've developed
- 14:06Speaker 2: and other things that we did and things that they
- 14:08Speaker 2: did themselves, and they would ultimately get many drugs approved,
- 14:13Speaker 2: but it took many, many years. That didn't take place
- 14:16Speaker 2: till two thousand and four.
- 14:18Speaker 1: Can you just list off some of the conditions diseases
- 14:22Speaker 1: that are treated with this, you know, technology, and the
- 14:25Speaker 1: offshoots of this technology that you came.
- 14:27Speaker 2: Up with, well, prostate cancer and ametriosis. I mean, there
- 14:31Speaker 2: are treatments for heart diseases, different eye diseases, schizophrenia, opioid addiction, osteoarthritis, diabetes.
- 14:42Speaker 2: I mean, I'm sure I'm leaving all out a lot,
- 14:45Speaker 2: but those are some.
- 14:49Speaker 1: Still to come on the show. How Robert Langer wound
- 14:51Speaker 1: up creating forty companies also the research he's excited about today.
- 15:09Speaker 1: So after you started that one initial company, you wound
- 15:13Speaker 1: up starting or being a co founder of a lot
- 15:16Speaker 1: of companies. I don't have the number in front of you.
- 15:18Speaker 1: It's dozens, the right order of magnitude.
- 15:20Speaker 2: Yeah, forty forty forty one.
- 15:22Speaker 1: Yeah, Like, how's that happen? Like? What how'd that happen? Well,
- 15:28Speaker 1: it's a lot of companies.
- 15:30Speaker 2: Yeah, but it's over it's over close to a forty
- 15:32Speaker 2: year period.
- 15:33Speaker 1: Well a company a year seems like a lot time.
- 15:36Speaker 1: I don't know.
- 15:36Speaker 2: Yeah, well, I mean I have a big lab, I
- 15:39Speaker 2: have a lot of graduate students. Some of the graduate
- 15:41Speaker 2: students would see what I did and bostocks and they
- 15:45Speaker 2: wanted to start companies. So we did. I mean, you know,
- 15:47Speaker 2: we may have done work in the lab for five
- 15:49Speaker 2: or six years, and then when it got to a
- 15:51Speaker 2: certain stage, we spun it out and some people with
- 15:54Speaker 2: other people, colleagues of mine, would see that, you know,
- 16:00Speaker 2: I had done this, and so they'd come to me
- 16:01Speaker 2: and talked to me about companies. So I you know, so, yeah,
- 16:05Speaker 2: we kept doing it. I mean, to me, it's it's
- 16:07Speaker 2: been a great route for taking discoveries in the academic
- 16:11Speaker 2: lab and getting them out to the world. You know.
- 16:15Speaker 2: And as I mentioned, I had a hard time, maybe
- 16:20Speaker 2: given the stage of the work, to get large companies
- 16:23Speaker 2: that would do it. So we did it ourselves.
- 16:27Speaker 1: And when you started your first company, I feel like
- 16:31Speaker 1: it was much less common for professors to start companies
- 16:36Speaker 1: than it is now. I'm curious sort of culturally, you know,
- 16:40Speaker 1: within MIT, within academia, how what was that like? Did
- 16:44Speaker 1: you get pushback.
- 16:46Speaker 2: I think anytime money's involved, a lot of people will
- 16:49Speaker 2: tell you and I think there's jealousy, you know, about it,
- 16:53Speaker 2: and people feel you shouldn't be spending your time doing that,
- 16:58Speaker 2: even at an MIT. So yeah, I had I ran
- 17:02Speaker 2: into problems when people were thinking about me for promotion.
- 17:07Speaker 2: You know, some one point I had a partial share
- 17:11Speaker 2: and they took that away from me. So yeah, I
- 17:15Speaker 2: was discouraging in the beginning. In fact, I'd say when
- 17:20Speaker 2: I was in the nutrition department, a lot of people,
- 17:23Speaker 2: some people told me that the drug delivery ideas they
- 17:26Speaker 2: would never work and I should be looking for a
- 17:28Speaker 2: new job.
- 17:30Speaker 1: Do you feel like you have have gained insight into
- 17:35Speaker 1: what that moment is or particular elements of that moment
- 17:39Speaker 1: when you take something that is basic research, academic research
- 17:44Speaker 1: and decide, okay, this is the moment we're going to
- 17:46Speaker 1: take the leap. We're going to start a company, We're
- 17:48Speaker 1: going to try and commercialize it. How do you know?
- 17:51Speaker 2: Well, I don't think you ever know for sure, but
- 17:53Speaker 2: the kinds of high level rules that I've used are
- 17:57Speaker 2: generally you have what I'll call is a platform technology,
- 18:00Speaker 2: meaning it's almost like a plug and play thing. Those
- 18:02Speaker 2: drug delivery systems are a good example, right, you could
- 18:05Speaker 2: use it for drug A, drug BA, DRUGSY. Then I
- 18:10Speaker 2: think the next thing is that you've taken at a
- 18:13Speaker 2: certain distance. Right, you have maybe animal data. You also
- 18:19Speaker 2: have a paper and ideally a good journal like say
- 18:23Speaker 2: Science or Nature. You have a patent or your high
- 18:26Speaker 2: likelihood of getting a patent because you've advanced a certain distance.
- 18:30Speaker 2: And usually there are people in my lab that want
- 18:33Speaker 2: to be involved in it and that we're So those
- 18:37Speaker 2: are the kinds of things that inform my thinking about
- 18:42Speaker 2: about it.
- 18:43Speaker 1: So what is something right now on the basic research
- 18:49Speaker 1: side that you're excited about. What is a big idea
- 18:51Speaker 1: that is early that you think holds a lot of promise.
- 18:54Speaker 2: Well, I think the tissue engineering work we're doing holds
- 18:57Speaker 2: a lot of promise. I mean an example that we're
- 18:59Speaker 2: doing is we're working with the Leeway Si who's head
- 19:03Speaker 2: of MIT's pick Hour Institute, and I have a wonderful
- 19:06Speaker 2: post doc Alice Stanton. You know, we're actually creating a
- 19:10Speaker 2: brain on a chip. It's not been published yet, but
- 19:13Speaker 2: she's been able to convert you know, like say we
- 19:18Speaker 2: could take your cells and convert it first ips cells
- 19:21Speaker 2: and then convert each of those, depending on what we do,
- 19:24Speaker 2: to a different brain cell type, six different cell types.
- 19:27Speaker 2: She's found a matrix that she can put them on
- 19:30Speaker 2: and that really makes them grow and function. And you know,
- 19:35Speaker 2: so that's that's something I'm excited about.
- 19:38Speaker 1: And what when you say put it on a chip,
- 19:41Speaker 1: what does that mean? And then what do you do
- 19:43Speaker 1: with my brain on a chip?
- 19:44Speaker 2: Yeah? Well, what I mean by in a chip, it's
- 19:47Speaker 2: in vitro. It's not in an animal, it's not in
- 19:49Speaker 2: a person. What it means is that you could rather
- 19:53Speaker 2: like you could think about if you were going to
- 19:55Speaker 2: experiment on a person. I mean, of course there's a
- 19:57Speaker 2: lot you wouldn't be able to find out anyhow because
- 20:00Speaker 2: we'd have to take you apart, and we're obviously not
- 20:02Speaker 2: going to do that.
- 20:03Speaker 1: I appreciate that.
- 20:03Speaker 2: Yeah, And with animals, you know, it's a little bit
- 20:07Speaker 2: similar here. So what you do with it is you
- 20:11Speaker 2: could literally test thousands and thousands of two thousands and
- 20:16Speaker 2: thousands of experiments and get readouts on them. So it
- 20:20Speaker 2: might someday reduce animal testing, hopefully also reduce human testing,
- 20:25Speaker 2: and may greatly speed up drug discovery. I mean there's
- 20:28Speaker 2: so many drugs that you'd like to be able to
- 20:31Speaker 2: have for brain disease, right, like for Alzheimer's, for Luke
- 20:34Speaker 2: Grigg's disease, als for Parkinson's. So I hope.
- 20:37Speaker 1: So brain disease has been famously difficult to treat with drugs, right.
- 20:41Speaker 1: It's a very very hard set of diseases, right because.
- 20:45Speaker 2: We don't understand it well enough and the tests are
- 20:48Speaker 2: very very hard to do. So something like this, if
- 20:51Speaker 2: it truly ends up working well, you know, could change
- 20:55Speaker 2: that someday. But that's an example of something I'm excited
- 20:58Speaker 2: about as you.
- 20:59Speaker 1: As you said, it's like it's a platform, right, Presumably
- 21:02Speaker 1: if you could do brain cells, you could do different
- 21:04Speaker 1: kinds of cells. It could be a way to do
- 21:06Speaker 1: lots of testing.
- 21:07Speaker 2: Well, we've done, yeah, we've put in this case we
- 21:10Speaker 2: have six different brain cell types in vitro. We have
- 21:14Speaker 2: our working on other cell types too. We have a
- 21:17Speaker 2: guest or intestinal track on a chip. We've had a
- 21:19Speaker 2: heart on a chip. And of course it's not just
- 21:22Speaker 2: putting them on chip. Someday you could use it for
- 21:25Speaker 2: repairing tissues, you know, you could maybe, I mean, in fact,
- 21:28Speaker 2: Laura Nicholson, one of my former postdocs. She runs a
- 21:31Speaker 2: company that's making new blood vessels that's been used on
- 21:35Speaker 2: patients in the Ukraine. Others have used made artificial skin
- 21:39Speaker 2: for burn victims or patients with diabetic skin ulcers, and
- 21:43Speaker 2: people are trying to make new cartilage, all kinds of tissues.
- 21:46Speaker 2: So yeah, so that is a big you know, that's
- 21:50Speaker 2: an exciting area.
- 21:51Speaker 1: And that tissue engineering side. I mean, does that go
- 21:54Speaker 1: back to a kind of similar origin story, right, I
- 21:57Speaker 1: know there was sort of early tissue engineering work that
- 22:00Speaker 1: you did as well. What was that work?
- 22:02Speaker 2: Yeah, well they are. One of the people I got
- 22:04Speaker 2: to meet at Children's Hospital is Jay Vacanti. He was
- 22:07Speaker 2: a pediatric surgeon is and he was treating patients with
- 22:11Speaker 2: liver failure and one day he came to see me said, Bob,
- 22:15Speaker 2: you know I do all these transplants, would it ever
- 22:18Speaker 2: be possible to make a liver from scratch? And he
- 22:21Speaker 2: and I brainstorm and came up with a way that
- 22:24Speaker 2: we hope might do that with polymer scaffolds and cells.
- 22:31Speaker 2: And so we've continued on working together and separately in
- 22:34Speaker 2: different ways to make this happen. But that started probably
- 22:40Speaker 2: over forty years ago, and that certainly was the basis
- 22:44Speaker 2: for a lot of these things.
- 22:45Speaker 1: So we can't synthesize livers yet. But what are some
- 22:48Speaker 1: of the clinical applications that have been found to some
- 22:51Speaker 1: of the research you did there?
- 22:53Speaker 2: Well, you can make artificial skin for burn victims. You
- 22:57Speaker 2: looks like we'll be able to make blood vessels. I
- 22:59Speaker 2: mean there have been clinical trials on a variety of things,
- 23:02Speaker 2: ranging from new spinal cord, repaired hearing loss, you know,
- 23:08Speaker 2: a lot of different things. But I think ultimately it's unlimited.
- 23:12Speaker 2: You know, you could theoretically use approaches like this if
- 23:15Speaker 2: you understand the right cells, the right signals, the right biology,
- 23:19Speaker 2: and the right engineering. I don't see that there's necessarily
- 23:22Speaker 2: any limit to what you could use it for, but people,
- 23:25Speaker 2: we need to understand it more.
- 23:30Speaker 1: We'll be back in a minute with the Lightning Round.
- 23:34Speaker 1: M M. I want to finish. We're almost done. I
- 23:45Speaker 1: appreciate your time. I want to finish with the Lightning Round,
- 23:48Speaker 1: which is just some quicker, kind of more random show,
- 23:51Speaker 1: maybe occasionally silly questions. Who is one engineer from history
- 23:57Speaker 1: who you wish more people knew about?
- 24:01Speaker 2: Boy? Well, I suppose a lot of people don't realize
- 24:04Speaker 2: maybe that Leonardo da Vinci was a very good engineer.
- 24:09Speaker 1: Good What are some of your favorite engineering work of Leonardo's?
- 24:13Speaker 2: Well, I mean he did all kinds of things. He
- 24:16Speaker 2: looked at at hearts, he looked at at you know,
- 24:20Speaker 2: you know, waterflow. I mean he did he did a lot,
- 24:23Speaker 2: not just art.
- 24:25Speaker 1: Who is the best teacher you ever had?
- 24:31Speaker 2: Maybe George Sieli at Cornell?
- 24:34Speaker 1: What about him made him such a good teacher?
- 24:36Speaker 2: Well, first, he cared a lot and he explained things. Well,
- 24:40Speaker 2: but I think caring a lot that that means a lot.
- 24:44Speaker 1: But you're also a magician, and I'm curious if there
- 24:47Speaker 1: are any skills from close up magic that have been
- 24:49Speaker 1: helpful to you in your day job.
- 24:52Speaker 2: You know, the one thing that does make a difference
- 24:55Speaker 2: with magic is presentation. So you know, if you give
- 25:01Speaker 2: if so what I learned in magic. If I make
- 25:03Speaker 2: a mistake, sometimes of course you make it deliberately. But
- 25:08Speaker 2: if I made an mistake, you know, it's part of
- 25:13Speaker 2: the show. You don't get upset, You just you know,
- 25:16Speaker 2: you just you just go with the flow. And what
- 25:19Speaker 2: I'd say is if I made a mistake from the talk,
- 25:22Speaker 2: same thing. You know, it's like you don't get flustered.
- 25:25Speaker 2: You just say you just keep going, and that does
- 25:28Speaker 2: make a difference.
- 25:30Speaker 1: So your research also helped to create, as I understand it,
- 25:34Speaker 1: a line of hair care products called living Proof. Jennifer Aniston,
- 25:39Speaker 1: who I will say had great hair before the company started,
- 25:42Speaker 1: is involved in that company, And so I'm curious, what's
- 25:46Speaker 1: your favorite living Proof product? And are you using it
- 25:49Speaker 1: right now?
- 25:51Speaker 2: Well, so I would say, you know, one of the
- 25:54Speaker 2: living Proof products is called PhD and stands for Perfect
- 25:57Speaker 2: hair Day.
- 25:58Speaker 1: Oh, Perfect hair Day? Okay, are you using it right now? So?
- 26:02Speaker 2: I use a shampoos okay, but gee, my wife and
- 26:06Speaker 2: my daughter and lots of people use lots of the products.
- 26:11Speaker 2: But I basically use it in the shampoo every so
- 26:14Speaker 2: often when my hair gets longer, I have, you know,
- 26:17Speaker 2: just a spray that I put on that doesn't make
- 26:19Speaker 2: it frize up so much.
- 26:22Speaker 1: Great. Is there anything else you think we should talk about?
- 26:27Speaker 2: Well, the only other thing I'd say that we've done
- 26:29Speaker 2: that we really didn't touch on is you know, we're
- 26:34Speaker 2: doing a lot of work with the Gates Foundation to
- 26:36Speaker 2: help the developing world, you know, and I'm excited about
- 26:39Speaker 2: that as well. I mean, they've been a big supporter
- 26:42Speaker 2: of our lab and he's done a terrific job in
- 26:46Speaker 2: terms of helping and it's I think the work is
- 26:49Speaker 2: leading to new kinds of nutrition, new kinds of oral
- 26:53Speaker 2: delivery that could last much longer than just a day
- 26:57Speaker 2: can lead. It's also leading to what we call self
- 27:00Speaker 2: boosting injections, so you wouldn't have to come back for
- 27:02Speaker 2: a second shot. So I think it's leading to a
- 27:04Speaker 2: lot of things that I hope will someday help a
- 27:06Speaker 2: lot of people, whether you not only in the developing world,
- 27:10Speaker 2: but everyone in the world period.
- 27:14Speaker 1: Of those technologies that you just listed, is any one
- 27:17Speaker 1: of them, particularly you know, farther along in development.
- 27:21Speaker 2: Well, several of them are already. I mean the pills
- 27:25Speaker 2: that you can swallow orally are in that lasts for
- 27:28Speaker 2: a week or a month. They're in phase three clinical trials.
- 27:32Speaker 2: There's a company Lindra that Geotraverso and I have start
- 27:36Speaker 2: that's probably the most advanced.
- 27:38Speaker 1: Is that for anti malarials or what is the first
- 27:41Speaker 1: application there?
- 27:42Speaker 2: The most advanced application of schizophrenias and phase three trial
- 27:46Speaker 2: It is in clinical trials from malaria too. Okay, but
- 27:49Speaker 2: that's like at phase one.
- 27:50Speaker 1: So Presumably that would be a big deal because drug
- 27:54Speaker 1: adherence is always a problem. People very often don't take
- 27:56Speaker 1: their drugs. Presumably people who are mentally ill might have
- 27:59Speaker 1: more trouble with adherents. So if you could have a
- 28:01Speaker 1: pill once a week instead of every day, that would
- 28:03Speaker 1: be a very large.
- 28:04Speaker 2: Impress Yeah, and also once a month. You know, we've
- 28:07Speaker 2: been working onto you know, like a once a mo
- 28:09Speaker 2: on birth control pill and yeah, so all those things,
- 28:12Speaker 2: do you know, things moving forward.
