Dr. Christopher Chang is a senior scientist in the Computational Science Center. He received a B.S. degree in biochemistry from Virginia Tech, and a Ph.D. for work on mechanistic aspects of lysine aminomutases with Dr. Perry Frey at the University of Wisconsin-Madison. After postdoctoral work on the manganese-dependent enzyme oxalate decarboxylase, he changed fields to focus on computational chemistry, particularly as applied to complex electronic structure in catalytic transition metal systems. At NREL, he has worked on modeling protein dynamics, comparative chemical bonding analysis in complex metalloclusters, electron transfer, and large-scale metabolic chemical models.
