Research

My research focuses on all aspects of hydrolytic enzymes, especially Zn-metalloproteases and glycoside hydrolases in order to understand their physiological function, in disease development and molecular evolution of bacterial life in oligotrophic environments.

My research interest spans across several disciplines of biological chemistry, focusing on the following areas:

Bacterial Oligotrophic Metabolism

  • Bacterial glycoside hydrolases and Caulobacter crescentus
  • Plant biomass-derived renewable materials
  • Bioinorganic chemistry/Chemical biology/Synthetic biology

Zn-Metalloprotease 

  • Glutamate Carboxypeptidase II functions in Caenorhabditis elegans
  • Membrane biochemistry
  • Role of metalloproteases in cell signaling and cancer metastasis.

Protein Functional Modulation Through Lipid-Protein Interactions 

  • Protein dimerization and functional modulation mediated by lipid-protein/protein-protein interactions.

Within my research, I use molecular biological/cloning techniques in bacterial and yeast expression systems to obtain the proteins of interest. Easy-to-handle eukaryotic model systems, such as C. elegans, functional genomic techniques, are employed to understand the functional significance of these metalloenzymes in eukaryotes.

Collaborative investigation of membrane protein dynamics through biochemical, spectroscopic and computational methods.
