My research focuses on how the sex hormones, estrogen and testosterone, affect non-reproductive tissues in the body. My primary research investigates how these sex hormones promote calcification of atherosclerotic plaques. Atherosclerosis is the major cardiovascular disease and calcification of plaques leads to more ruptures causing heart attacks and strokes. The work performed in my laboratory is aimed at improving the understanding and safety of hormone replacement treatment use.
My research team also develops bioassays for the detection of designer androgens and estrogens that are used as doping agents in sports.
