International Trade Global Value Chains Food Price Volatility Agricultural Markets Geopolitics of Food

I study uncertainty in international agricultural trade and global agri-food value chains — how participation in global value chains shapes food prices and price volatility, how firms manage supply-chain risk, and how geopolitical pressures reshape food policy. My research features data-science approaches and carries a strong policy focus.

My work has been covered in The Wall Street Journal, CNN Business, Yahoo Finance, Newsweek, and USA Today.
