My work at StreetEasy uses econometrics and data science to better understand the New York City real estate market and its interactions with the local, national, and global economies. I produce frequent analysis on economics, real estate, and personal finance for New Yorkers. As StreetEasy’s spokesperson and commentator on market trends, my analysis has been quoted in The Economist, New York Times, Wall Street Journal, Bloomberg,, Forbes, Vox, Business Insider, Architectural Digest, New York Observer, and Curbed, and I have appeared on CBSN, Fox5NY, and NY1.

Global Economics

Over the course of more than six years with the Federal Reserve, I covered U.S. monetary policy, emerging market financial policy, and the U.S. international investment position. My work on evaluating and contextualizing monetary policy options was featured on the New York Fed's Liberty Street Economics blog. During my time with the Federal Reserve, I visited and collaborated on economic policy initiatives in Switzerland, the U.K., Brazil, Russia, Turkey, and Hungary.

Digital Commerce

With Capital One, I helped lead efforts to better understand customer data, including spending patterns and merchant trends. Working on the Capital One's interaction intelligence platform, I designed and developed algorithms to match consumer transaction data to merchants in the real world. My team's work can be found in the Capital One Mobile app and on Capital One's DevExchange.
