Research Focus

The theme of the lab is to understand cell biological processes and the host defence mechanism following the footprints of the viruses- like a secret investigator in mission mode! We are interested in studying majorly but not limited to RNA viruses. Some of our thrust areas have been cholesterol homeostasis, cellular trafficking and interferon signalling pathways. Another area of interest of our lab is to study- why salivary glands act as virus reservoirs of our body? We are trying to understand from immunological aspects and the role of salivary gland resident microbiome in hosts ranging from mice to human clinical samples. The overall goal of our lab is to develop translational strategies against viral infections- a solution from bench-to-bedside. We employ wild-type and transgenic mice and organoid cultures for our study along with confocal microscopy, flow-cytometry, high-throughput single cell transcriptomics, RT-PCR and conventional molecular biology and cell culture techniques. We believe in inter-disciplinary science for enhancement of our understanding of various virology phenomena, so we are open for new collaborations and technologies.

Research Interest

  1. Investigating the reason behind viral persistence in salivary glands. 
  2. Immune response against virus trafficking inside exosome/extracellular vesicles.
  3. Understanding role of lipid droplets in cholesterol homeostasis and viral replication.
  4. Drug targeting potential host proteins important for various metabolic processes forming the mainstays for virus replication, assembly or trafficking. 

 If you are interested in our research and passionate about viruses please do send a detailed Curriculum Vitae and a brief research summary with a subject line: “Research Interest to Sourish” (see contact information). Ph.D students are encouraged to apply through proper channel as per norms of CSIR- Indian Institute of Chemical Biology. Postdoctoral candidates having their own grants should apply with a write up explaining their area of expertise and how they plan to align with the lab interest and a CV. The lab does NOT accept short-term trainees/interns, however candidates interested to dissertations are welcome.
