Talia Gillis is a legal economist who studies the intersection of law and household finance. Her wide-ranging research has delved into household financial decision-making with the goal of informing financial regulation and policy. She has written about the ways in which financial regulators perceive their roles and critiqued the validity of tests of financial disclosure laws. Her empirical research focuses on mental accounting and how it relates to spending and saving behavior. She is also currently working on the regulation of credit markets through the enforcement of discrimination laws when credit is priced using big data and machine learning.

Gillis joined the Columbia Law faculty in 2020 after completing a S.J.D. degree at Harvard and pursuing a Ph.D. in economics (pending). At Harvard, she was a John M. Olin Fellow in Empirical Law and Economics, a Terence M. Considine Fellow in Law and Economics, and a Program on Negotiations Fellow.
