Structural Biology

Jason Phan, Ph.D. is a Research Assistant Professor of Biochemistry and a structural biologist in the Fesik lab. His area of interest includes protein engineering, expression, purification and X-ray crystallography. Jason received his Ph.D. in Biochemistry at the University of South Carolina, Columbia in 2001 under the mentorship of Professor Lukasz Lebioda and postdoctoral training with Dr. David S. Waugh at the National Cancer Institute in Frederick, Maryland. At the end of 2005, he accepted a senior staff scientist position at the Moffitt Cancer Center in Tampa, Florida to build and operate a core facility for protein production and X-ray crystallography. Jason is a member of the American Crystallographic Association and a program member of the Vanderbilt-Ingram Cancer Center.
