I am an Associate Professor of Law at Columbia Law School. My work sits at the intersection of law, finance and data science. In January 2018, I taught a new course on data science for lawyers in Columbia’s J-term. I also write and teach on securities regulation, corporate law, banking and financial regulation, and contract law.

My recent projects study informed trading on cybersecurity data breaches, information leakage and hedge-fund activism, insider trading on corporate disclosures, information transmission in financial markets, and whether consumers keep promises they make themselves.
