Key areas of my Research: Cardiovascular remodeling, Heart failure, Diabetes, Angiogenesis, Mitophagy, Micro RNA and Stem cells.

The end result of most of the cardiovascular disease conditions is compromised blood supply to the myocardium. Angiogenesis being key modulating factor in cardiac pathology, I look at angiogenic factors and anti-angiogenic factors that are involved during cardiac disease state. My research area of interest is looking at the various key factors that are involved in cardiovascular remodeling during various cardiovascular disease states like pressure overload condition (Aortic banding), coronary artery disease (Myocardial infarction). Recently, I am also looking at micro RNAs that are involved in cardiovascular pathology during diabetic condition.
