Millard Henry Alexander (born February 17, 1943, Boston, Massachusetts) is an American theoretical chemist. He is Distinguished University Professor[2] at the University of Maryland, with appointments in the Department of Chemistry and Biochemistry[3] and the Institute for Physical Science and Technology.[4] He is the author of over 300 publications and an active researcher in the fields of molecular collision dynamics and theoretical chemistry.
Alexander's research focus is the quantum-mechanical aspects of molecular collisions, in particular those involving open-shell species. More specifically, Alexander's work has focused on understanding chemical reactions where the Born–Oppenheimer approximation can be violated, by means of nonadiabatic coupling, spin–orbit interactions and conical intersections.[1] Alexander's work is particularly important in understanding the and reactions.[5] [6]
Alexander is a fellow of the American Physical Society and of the American Association for the Advancement of Science and a member of the International Academy of Quantum Molecular Science. In 2015 he received the Herschbach Medal for contributions to the theoretical study of the dynamics of molecular collisions.[7]
Since 2012 Alexander has served as the President of the Telluride Science Research Center.[8]
