My research investigates the evolving function of financial markets in an era increasingly shaped by algorithms, big data, and artificial intelligence. I study core issues in asset pricing and investments by leveraging diverse tools from economic theory, machine learning, and statistical physics. Much of my work addresses questions of broad relevance and high policy stakes, including how algorithmic trading affects market stability, how position limits influence commodity markets, and how new technologies reshape price efficiency and investor information processing.  

My contributions span three interconnected areas: (1) Machine Learning: my research develops the economic foundations for advanced, widely used machine learning techniques, such as LASSO, Elastic Net, and attention mechanisms. (2) Market Microstructure: my papers analyze sophisticated issues with direct regulatory concerns, such as controversial trading rules and the regulation of destabilizing or manipulative trading practices. (3) Asset Pricing Theory: my work revisits hidden assumptions critical to standard financial theory, corrects pervasive misconceptions regarding risk-neutral pricing and the no-arbitrage argument, and offers new perspectives that help resolve various asset pricing puzzles and anomalies.   

Across these themes, my aim is to deliver rigorous theory with sharp insights relevant to the broader financial ecosystem, including financial economists, policy makers, and asset managers. My work has been presented at leading international finance conferences (e.g., WFA, EFA, SFS Cavalcade, NYU Stern Microstructure) and at major regulatory institutions, including the U.S. Securities and Exchange Commission (SEC) and the Bank for International Settlements (BIS). My strong interdisciplinary foundation, including prior experience as a theoretical physicist on NSF- and NIH-funded projects, uniquely equips me to tackle the most challenging, high-stakes problems facing modern financial markets.
