I am currently an Assistant Professor of Health Policy and Management in the Mailman School of Public Health at Columbia University. I’m also a Faculty Research Fellow at the National Bureau of Economic Research and an Affiliate of the Abdul Latif Jameel Poverty Action Lab. I received my PhD in Economics from MIT in 2014 and then served as a Robert Wood Johnson Scholar in Health Policy Research at Harvard University before coming to Columbia.

My research studies the economics of health care payment policy, with a focus on documentation and coding, upcoding, and fraud. My dissertation analyzed how hospitals learned to use more detailed diagnosis descriptions on their insurance claims to take advantage of a revenue-raising opportunity in Medicare. I am currently an investigator on two randomized controlled trials, one focusing on inappropriate prescribing in Medicare Part D and the other looking at insurance choices in the Affordable Care Act marketplaces.
