Alexander Tan Limkakeng Jr.
Associate Professor of Surgery
My personal research interest is finding new ways to diagnose acute coronary syndrome
. In particular, I am interested in novel biomarkers and precision medicine
approaches to this problem. As Vice Chief of Research for the Duke Division of Emergency Medicine, I also work with researchers from many fields spanning global health, innovation, clinical trials, basic discovery and translational research. The common element is time-sensitive health conditions. I help to oversee a team of research professionals in multicenter emergency department studies funded by the National Institutes of Health, foundations, and industry partners.
Current Research Interests
Acute Coronary Syndrome, Biomarkers, Myocardial Ischemia, Precision Medicine, Septic Shock, Pain Management, Clinical Trials
