Dr. Pozharskiy received his Ph.D. in 1998 from the Institute of Theoretical and Experimental Biophysics of Russian Academy of Sciences, and initially trained as a postdoctoral fellow in the Department of Biochemistry of Northwestern University. He then pursued postdoctoral training in X-ray crystallography in Rosenstiel Basic Medical research Center at Brandeis University.  Dr Pozharskiy was an assistant professor in the Department of Pharmaceutical Sciences of University of Maryland School of Pharmacy and joined the Department in 2013 as a member of Center for Biomolecular Therapeutics.  He holds concurrent appointment as a Fellow at the Institute for Biosciences and Biotechnology Research.

Dr Pozharskiy's area of scientific expertise is structural biology, with major focus on protein X-ray crystallography and single particle cryoelectron microscopy.  Throughout his career as a structural biologist, he has focused on structural mechanisms of molecular recognition in variety of biomolecular systems, including small molecules, protein-DNA and protein-protein interactions.  He has also contributed to methodological aspects of protein crystallography, including computational methods, structure validation, and crystallization methods.

Research/Clinical Keywords
