A couple of years ago, the National Cancer Institute put out a grant or request for proposals in the area of nanotechnology and cancer, and so some of my colleagues asked if I would help put something like that together. So we got a group of really wonderful biologists at MIT, and I asked a group of engineers, and we got probably about 15 of us together. And we came up with these ideas about targeting nanoparticles to tumors, new materials for ultra-rapid diagnostics, new materials for imaging, so that you might detect the cancer earlier. So those are all really, to me, interesting examples of how you can take, on the one hand, engineering and material science, and on the other hand, biology and medicine, put them together and try to create new things that can maybe someday improve cancer therapy and diagnosis. Actually, we were fortunate enough to get that grant, and continue to get it, and I think it’s doing a lot of good.
