I am a fifth-year PhD student at the University of Chicago Harris School of Public Policy, a student affiliate in the Healthcare Markets and Regulation Lab at Harvard Medical School, and a predoctoral fellow (AY 2021-24) in the University of Chicago and Northwestern University Health Services Research Program. 

My research lies in the intersection of health economics and public finance, focusing on social insurance and agency conflicts.

I received my MSc. in Econometrics and Mathematical Economics from the London School of Economics and my B.A. in Applied Mathematics, Economics, and Statistics from UC Berkeley. Before Harris, I worked as a research professional at the Becker-Friedman Institute Ronzetti Initiative for the Study of Labor Markets.

Disability and Distress: The Effect of Disability Programs on Financial Outcomes,”
with Manasi Deshpande and Tal GrossManuscript. Online Appendix

American Economic Journal: Applied Economics, 13(2), April 2021, pp. 151-78
Winner of the 2024 AEJ Best Paper Award: Applied Economics

Abstract: We provide the first evidence on the relationship between disability programs and markers of financial distress: bankruptcy, foreclosure, eviction, and home sale. Rates of these adverse financial events peak around the time of disability application. Using variation induced by an age-based eligibility rule, we find that disability allowance reduces the likelihood of bankruptcy (0.77 percentage point or 31 percent), foreclosure (1.8 percentage point or 34 percent), and home sale (1.8 percentage point or 15 percent). We present evidence that these changes reflect true reductions in financial distress. Considering these extreme events increases the optimal disability benefit amount and suggests a shorter optimal waiting time.
