Research Interest

Cardiovascular disease (CVD) is the leading cause of death in the developed as well as in the developing world. The annual mortality of CVD is expected to reach 23.6 million by 2030. Our lab research interests are in understanding molecular mechanisms of cardiovascular disease. Our principal approach is to determine cryo-EM or X-ray structures of proteins involved in such diseases and their downstream signaling components alone and in complex with key-regulators, and then test structure -derived hypotheses via a battery of functional assays. The underlying rationale is that a better understanding of the molecular and cellular mechanisms that underlie the regulation of these proteins will accelerate development of novel therapeutics. A major focus of our lab has been the structure and function of lipid modulating proteins like the PNPLAs and membrane proteins like ABCs, which are dysregulated in chronic disease such as heart failure and neurodegenerative diseases.

The main focus is to study disease biology and empower medicine to achieve a more optimal view towards therapeutic interventions by elucidating the structures and functions of the proteins involved in cardiovascular diseases and neurodegenerative disease. This structural and functional analysis will further help us to promote wellness against some globally alarming diseases like atherosclerosis and Alzheimer’s Disease by drug development as a long-term aim.
