Research interest 

The main focus of my lab is to use the application of state-of-the art NMR spectroscopy and other biophysical methods, including CD, Fluorescence etc. in conjunction with molecular modeling techniques to address the following projects:

  1. Designing of novel antifreeze peptides with potential applications in many areas such as medicine, agriculture and industry.
  2. Receptor-ligand interaction study to develop structure based drug design.
  3. Novel Antimicrobial peptides (AMPs) to develop antimicrobial and antisepsis drugs.
  4. Structure and dynamics study of amyloid beta (Ab40) protein in micelle environment.
  5. Designing of novel cell penetrating peptides (CPPs) and its function for drug delivery.
  6. Structure-function correlation for Myelin-Associated Glycoprotein (MAG), responsible for inhibition of axon regeneration in the central nervous system (CNS).
  7. DNA-antimicobial peptide (AMP) interaction study to understand the mechanism of action for AMPs to kill the bacteria.
  8. de novo designed small loop to stop protein aggregation.
  9. Structure determination of c-terminal of Raf1 kinase: Implications in a signaling pathway.
  10. Exploring the self-assembly of short peptides: Applications to nanoparticle/hydrogels/fibrillation.
