Dr. Robert Langer's Lecture

His lecture was fascinating because Dr. Langer's work showed how engineering (applications of sciences) could save or significantly improve lives. I was surprised by the number of his projects and the number of people (different doctors, researchers, scientists, and engineers) he worked with. 

Some of his projects included nanoparticles that bind to desired cancer cells so that these cells could be identified and microchips injected under one's arm with wells containing different drugs that could be controlled using a cell phone or a computer. 

I personally liked the Powerpoint slide showing the reasons NIH reviewers gave during many different years for rejecting the project grant applications. This showed how difficult this job is and how much time and effort it takes to produce drugs or medical devices that could help people.
