Area of Interest:

  • Molecular Biophysics, Structural and Computational Biology

Summary of research:

Research in my laboratory is mainly concerned with understanding the effects of mutational as well as environmental perturbations on protein structures mainly through the use of molecular dynamics simulations. We are also interested in the comparative sequence analyses of specific protein families particularly those associated with bacterial pathogenesis and fungal drug resistance.
