Big Thinkers is a former ZDTV (later TechTV) television program. It featured a half-hour interview with a "big thinker" in science, technology, and other fields. Interviews were filmed in a 16:9 format and intercut with public domain material from the Prelinger Archives. This archival footage (mostly film clips from the 1940's and 50's) was used to create visual metaphors highlighting the speaker's points.

He was formerly the Germeshausen Professor of Chemical and Biomedical Engineering and maintains activity in the department of chemical engineering and the department of biological engineering at MIT. He is also a faculty member of the Harvard-MIT Division of Health Sciences and Technology. He is a widely recognized and cited researcher in biotechnology, especially in the fields of drug delivery systems and tissue engineering. Dr. Langer's research laboratory at MIT is the largest biomedical engineering lab in the world, maintaining about $6 million in annual grants and over 100 researchers.
