• I am an associate professor in the department of Epidemiology at the University of Alabama at Birmingham (UAB). After working as a statistician/epidemiologist, I have accumulated more than 10 years of experience in the study design, analysis, and methodological development using a variety of data system, including electronic medical records, Medicare, Medicaid, SEER, commercial administrative data, and patient surveys. At the same time, I have established strong collaboration with experts on a variety of projects. With a focus on chronic disease, such as osteoporosis, cancer and auto-immune diseases, my current work is mainly related to comparative effectiveness research, pharmacoepidemiology, drug safety and patient reported outcomes.
