The Physiology Course is an intensive seven-week laboratory summer course that has run for over 125 years. It is designed to bring together senior PhD candidates and early post-doctoral researchers to work on cutting-edge questions in cell physiology. Work carried out by students and faculty at the course have led to numerous primary research publications and also a Nobel Prize (Tim Hunt, discovery of cyclins). Waterman has also participated as a faculty member in many courses in advanced quantitative light microscopy, both within the United States as well as in Austria, Portugal, India, and Germany. A large fraction of Waterman’s former trainees now hold faculty positions at academic and research institutions around the world.
