My research focuses on the economics of aging. It considers issues related to the effects of patients’ choice of healthcare provider on health outcomes and healthcare utilization patterns, the effects of regulations on healthcare markets, disparities in the quality of healthcare services received between racial and socio-economic groups, and the effects of Medicare Advantage on the healthcare system. My goal as a researcher is to apply or develop appropriate econometric techniques that can provide causal answers to these questions. I have over 110 publications in leading journals, including the Journal of Health Economics, Health Affairs, Alzheimer’s and Dementia, and JAMA. Supported by the National Institute on Aging (NIA) and various foundations, I have completed five research projects and currently lead five R01 or equivalent projects as Principal Investigator. Given my expertise in advanced econometric techniques, I also contributed as the main methodologist or co-investigator for numerous research projects. I taught a graduate-level two-course sequence of health services research methods. I have also served as an advisor to students in the Health Services Research Doctoral Program, post-doctoral fellows in our T32 Training program, and junior faculty members.
