Research Interests

Our laboratory is interested in understanding and harnessing the power of biomolecular interactions. Biological systems thrive as a result of complex intermolecular interactions and deciphering these will help engineer products and processes that are critical to our day to day needs. We utilize molecular dynamic simulation assisted techniques to understand processes at a molecular level followed by experimental verification.

Some example projects that we continue to be involved in include:

  • Enzyme-substrate-ligand interactions (for bioenergy, biosensing applications)
  • Protein-ligand interactions (antiviral agents, antimicrobial agents, drugs)
  • Catalysis (bioenergy, fuel cells)
  • Surface functionalization (SAMs, separations)

We use Enhanced Ligand Exploration and Interaction Recognition Algorithm (ELIXIR-A), a platform under development in our laboratory, that uses molecular dynamics simulations to analyze intermolecular interactions for underpinning interaction points. We have the capability of sending multiple ligands simultaneously toward a receptor in an environment that closely resembles a cellular/solvent environment while the protein receptor is flexing. Interaction points identified from such a dynamic environment can be used to make highly accurate predictions of ligand-receptor behavior in the real world. We use these interaction points to understand catalyst-substrate-inhibitor behavior at a molecular level. We are using ELIXIR in high-throughput ligand (inhibitor) screening, elucidating electronic signaling in oxidoreductases and even in the development of synthetic enzymes.
