Welcome to my website!

I hold a PhD in Economics, with concentrations in Financial Economics, Industrial Organization, and Econometrics, from the University of Illinois at Urbana-Champaign. I have been an Assistant Professor of Finance at the Argyros College of Business and Economics at Chapman University since 2018 (I was on leave 2021-2022). I have also served as a Financial Economist at the Securities & Exchange Commission from 2021 to 2024. Before joining Argyros College, I was an Assistant Professor of Economics at Ohio University from 2015 to 2018. My research interests include Market Microstructure, Security Markets Regulation, and Behavioral Asset Pricing. I have taught undergraduate- and graduate-level courses in Investments, Corporate Finance, and Business Statistics.
