Upasana Ray , Ph.D.
Senior Scientist & Deputy Head
Infectious Diseases and Immunology
1. Understanding virus assembly process and exploring novel bio-molecular platforms for self assembly, displaying viral proteins (Virus like particles or VLPs). VLPs would be designed with an objective to make vaccine candidates or for drug delivery
2. Exploring virus mediated horizontal gene transfer and its possible implications.
3. Studying viral entry process and viral tropism
4.Dissecting molecular interactions between viral proteins and host cell with an aim to design antiviral candidates.
Currently, the focus of the laboratory is Dengue virus.
