Current Research and Scholarly Interests The commonest heart rhythm disorder is atrial fibrillation (AF). AF is a problem as it can lead to strokes and heart attacks. It is difficult to cure, with many tablets required that are only partially effective. A new way of selecting areas for ablation (burning) focusses on rotors - areas where electrical waves spin like a hurricane. At Stanford, I am working with the developer of this technique to improve understanding of why these occur at certain sites and how better to identify these.

Current Research and Scholarly Interests My academic and scientific training has been focused on design and development of novel fiber-optic based biomedical instrumentation to improve the detection and, intervention, and treatment of various diseases. Currently, I am on a Western State Affiliate Winter 2013 Postdoctoral Fellowship from the American Heart Association (AHA) at the Stanford University School of Medicine in the laboratory of Professors Lei Xing and Michael V. McConnell, where I developed a novel fiber-optic catheter based optical imaging system to detect vulnerable atherosclerotic plaque in carotid arteries. In this work, I developed a novel scintillating balloon which can detect the vulnerable atherosclerotic plaque from stable plaque with high sensitivity after 18F-FDG uptake by the macrophages within the thin cap fibro atheroma (TCFA). The TCFA causes 60-70% of acute coronary syndrome that leads to sudden cardiac death and myocardial infarction.

Current Research and Scholarly Interests Our laboratory focuses on translational research in 2 main areas - genomic approaches to diagnosis and minimal residual disease testing for patients with cancer, and molecular basis of disorders of thrombosis and hemostasis. My clinical focus is in diagnosis and treatment of disorders of hemostasis and thrombosis and general hematology.
