Dr. Biswas earned her PhD in Molecular Bioscience from Rutgers/UMDNJ, Piscataway, NJ; her MS degree in Biochemistry from the University of Maryland, Baltimore, MD, and her BS degree from the University of Washington, Seattle, WA.

Her current research interests are in the analysis of the structure and function of biologically important proteins, which involves genetic and biochemical characterization of recombinant proteins generated through in vitro mutagenesis. Projects currently underway are: (i) Molecular analysis of inherited visual diseases, and (ii) Hexameric DNA helicases and control of cell proliferation. These projects are described in detail in the "Molecular Biology Research" section of this web site.
