The "Kollman era", 1975-2001

Peter and Tom Cheatham modeling DNA

The forty-year history of Amber builds on the foundational contributions of Professor Peter A. Kollman at the University of California, San Francisco, who died shortly after being diagnosed with cancer in 2001. Peter's vision, leadership, and insights echo in our work today. Amber is dedicated to his memory.
