    1. Dr. Manidipa Banerjee's Group

      Dr. Manidipa Banerjee's group is using both experimental and computational approaches to understand the mechanisms and dynamicity of various processes of viruses, including virus assembly and disassembly, and virus interaction with host-cell receptors and membranes. We intend to use these studies to design virus-based macromolecular complexes for various biomedical applications like vaccines and drug delivery systems.

      We have been utilizing the HPC cluster at IIT for our computational work, which falls under two broad categories:

      • Molecular dynamics simulation studies to understand how viral peptides interact with biological membranes at the atomic scale: Simulation software packages like GROMACS and AMBER are being used for this purpose.
      • Cryo-electron microscopy-single particle reconstruction for near-atomic structure determination of virus-like particles: For this we have been using the image processing suites EMAN2, RELION and Scipion.
