As an undergrad, I looked up to so many graduate students in the Computation and Neural Systems department and wanted to be just like them. They taught me a ton about the brain and math and how to do research. Every now and again I look on Google to see what my heros are up to...today I was curious about Sam and unfortunately Google brings me sad news. I remember his enthusiasm, his feedback on my homework, a lecture he gave on expectation-maximization with a demo he was really excited about...he always had a smile on his face. He is missed.
