Shortly after this talk I tried to get grant money to help do different projects. And I remember writing one grant to the NIH on cancer and I got the reviews back, which were really, really negative. They not only didn’t give me the money, they said, “Well, how could Dr. Langer do this?” They said, “He’s a chemical engineer. He doesn’t know anything about biology, and he knows even less about cancer.” I wasn’t sure how that was possible to know less than nothing, but somehow that was the review. Anyhow, also, when I was done with my postdoctoral work I applied for different faculty positions to different chemical engineering departments. But when I did that, I had a lot of trouble getting a job, because they all felt I wasn’t doing engineering. They felt it was more biology. So I ended up joining what was called the Nutrition and Food Science Department at MIT. But in that department what happened was, about a year after I got the position, the chairman of the department left. So then a number of the senior members of the department decided they’d give me advice, and their advice was I should start looking for a new job. So there I was. I was getting my grants turned down, people didn’t believe in my research, it appeared like I wasn’t even going to get to be an associate professor. But fortunately, what happened over the next few years is different people in academics and in pharmaceutical companies started using a lot of our principles, and things slowly began to turn around.
