About Me

I am currently a fourth year PhD student in the Department of Biological Sciences and I’m co-advised by Dr. Bystroff and Dr. Dordick.

Former Education

B.S. in Biology from St. John’s University
M.S. in Biology from St. John’s University


My research focuses on protein folding and understanding the mechanisms that drive proteins to more favored conformations verses others. Enhancement of our knowledge of those factors that drive conformational predominance in protein structure can be used to engineer novel properties into existent proteins. I am working on re-engineering the green fluorescent protein (GFP) from the jellyfish Aequorea victoria. In redesigning this protein we are attempting to develop tunable biosensors that can be used to detect small chemical molecules or proteins. The target of design efforts is the Dengue virus.
