Assistant Professor of Chemistry

Ph.D. in Chemistry University of North Texas, Texas, 2007
M.S. in Chemistry University of North Texas, Texas, 2004
B. Eng. in Chemistry Polytechnic University of Bucharest, Romania, 1993

After obtaining her Ph.D. in Chemistry, Adriana Dinescu served as a post-doctoral fellow at the Idaho National Laboratory for almost two years. Since 2008, she has taught a variety of chemistry courses at Butler University in Indiana and Wilkes University in Pennsylvania, before joining Centenary University in January 2016. Her research interests include bio-inorganic modeling and simulation, energy efficient catalysis, biomedical research, and structure-based drug design.
