Cancer research isn’t a traditional career track for a chemical
engineer. But Robert Langer, ScD, isn’t an ordinary chemical engineer.
After completing his doctoral degree in 1974, he turned down offers from the
petroleum industry to take a postdoctoral position with cancer researcher
Judah Folkman, MD, at Children’s Hospital, in Boston.
Langer’s task in Folkman’s laboratory was to isolate the
first angiogenesis inhibitor (Langer et al. Science. 1976;193:70-72).
One crucial aspect of this challenge was to come up with a plastic, or polymer,
delivery system that would slowly release these large protein molecules to
tissues in a controlled manner.
