PhD Candidate

Johns Hopkins University


I am a PhD Candidate at Johns Hopkins University interested in health care economics and applied econometrics. My research examines policy-relevant questions related to competition, consolidation, and vertical integration in health care markets. In prior and ongoing research, I have studied strategic acquisitions of physician practices by private equity funds and their effects on physician practice patterns, including physician referral behavior.

I work with large databases of medical claims and have been trained in advanced econometric methods, experimental design, and causal inference methods to generate insights from observational data and randomized experiments.

My teaching experience includes a diverse set of courses in health economics, health care finance, and the business of health to MBA, MPH, MHA, and Ph.D. students at the full-time and executive level. My research has been published in peer-reviewed journals such as Journal of the American Medical Association (JAMA) Network, Health Services Research, and Milbank Quarterly.

Before graduate school, I worked as a Senior Analyst in the Antitrust and Competition practice of National Economic Research Associates (NERA) in New York. I hold a graduate degree in international finance and economic policy from Columbia University and a bachelor’s degree in mathematics and economics from Bryn Mawr College.
