Das Viswanath M.Sc., Ph.D.
I am primarily interested in bioactive compounds (both natural and synthetic) as therapeutic candidates for cancer and tauopathies. My current work focuses on the use of 3D cell models for hit validation and studying the effects of the spatial dimension and tumor-stroma interaction on cancer cell response to anti-cancer agents. We also use these 3D models to understand the intricacies of the hypoxic microenvironment in the development of resistance to microtubule-targeting drugs. Another aspect of my current research is focused on biochemical and structural studies of tau for the identification of tau anti-aggregation agents for the treatment of tauopathies, such as Alzheimer's disease.
