I am a financial economist at the Federal Deposit Insurance Corporation (FDIC) and lecturer at the Johns Hopkins University. My research interests include credit risk modeling, stress testing, applied microeconomics, and computational statistics/econometrics.

Here are links to my Google Scholar, FDIC page, JHU profile, and UCI website.
