James Andrew McCammon (born 1947, Lafayette, IN) is an American physical chemist known for his application of principles and methods from theoretical and computational chemistry to biological systems. A professor at the University of California, San Diego (UCSD), McCammon's research focuses on the theoretical aspects of biomolecular and cellular activity. In 2011 he was elected to the National Academy of Sciences
Dr. McCammon co-authored "Dynamics of Proteins and Nucleic Acids" (Cambridge University Press, 1987), the first text on molecular mechanics and molecular dynamics, with Stephen Harvey.
With Martin Karplus and Bruce Gelin, he published the first molecular dynamics simulation of a Bovine Pancreatic Trypsin Inhibitor BPTI.
