Dr. Gupta received her Ph.D. from Nanyang Technological University, in 2013. She worked under the direction of Dr. Surajit Bhattacharjya in the high field magnetic laboratory to understand the protein folding and dynamics and their functional implications. Her postdoctoral work in the same lab revealed the serine phosphorylation dependent regulation of integrin function. Later she joined the group of Dr. LiuChuan Fa, where she was exposed to solid-phase peptide synthesis and protein/peptide ligation techniques. Her final postdoctoral training was with Dr. Robert Tycko at the prestigious Laboratory of Chemical Physics, NIDDK, National Institutes of Health, Bethesda, USA. She established intein based protein ligation method for HIV-1 mature and immature capsid protein there. These specially labeled samples were used for solid-state NMR based characterization of the immature and mature capsid core and to determine the mechanism of action of the maturation inhibitors of HIV-1. Dr. Gupta holds certificates on ‘Research Ethics’ from NIH which is personalized for scientists.

In her present assignment at YRC, she is setting up a Structural Biophysics Laboratory to work on the bacterial and viral proteins and protein modifications aided towards the biomedical needs.

Research

  • Structural Virology and peptide therapeutics

The objective of our lab is to study the biomolecules. We are especially interested in dissecting the role of viral proteins in viral replication cycle and their interaction with host factors to decipher the new therapeutic targets using multidimensional solution-state and solid-state NMR spectroscopy, Electron Microscopy, Dynamic Light Scattering, Circular Dichroism, Isothermal Calorimetric Technique, Fluorescence spectroscopy and other biophysical tools. The following areas will be explored towards achieving this goal;

  • Biophysical Chemistry: Protein/peptide structure and dynamics
  • Structural Virology:Structural characterization of the viral proteins
  • Drug designing: Biophysical cauterization of the cellular and viral determinant for drug designing
  • Biomaterials: Protein ligation and modifications for biomedical application
