Expertise:

Protein Design & Engineering, Spectroscopy, Molecular Biology, Biochemistry, Biophysics.

Profile:

The two major research areas in my lab are: a) investigating protein folding mechanism using extracellular proteins such as proteases and their protein-based inhibitors implicated in human disease, as model systems and, b) developing protein expression technologies for producing protein-based biotherapeutics. The specifics of our research activity include:
  • Investigating folding, mis-folding and functioning of plasma serpins
  • Rational re-designing of human alpha-1 antitrypsin and plasminogen activator inhibitor-1 to develop these as improved therapeutic biologics
  • Designing & biophysical characterization of fluorescent protein-based biosensors
  • Developing technologies for expressing monoclonal antibodies and performing biochemical and biophysical characterization of mAbs.
