Jim Gatheral is researcher in the field of mathematical finance, who has contributed to the study of volatility as applied to the pricing and risk management of derivatives. A recurrent subject in his books and papers is the volatility smile, and he published in 2006 a book The Volatility Surface based on a course he taught for six years at New York University, along with Nassim Taleb. More recently his work has moved in the direction of market superstructure, especially as applied to algorithmic trading. He is the author of The Volatility Surface: A Practitioner's Guide.

In March 2010, Jim Gatheral left his position at Merrill Lynch to assume a tenured full professor position at the Financial Engineering Masters Program at Baruch College where he is teaching volatility surface modeling and market microstructure. In April 2013, Jim was named Presidential Professor at Baruch College. Prior to this, he worked at Bank of America and Bankers Trust before heading the Equity Quantitative Analytics group at Merrill Lynch in 1996, where he was a managing director for 17 years. In 1998 he became a fellow of the Masters Program in Mathematical Finance at the Courant Institute of Mathematical Sciences at New York University, where he was an adjunct professor for 12 years.
Dr. Gatheral received his PhD in theoretical physics from Cambridge University (1983), and a B.Sc. in Mathematics and Natural Philosophy from the University of Glasgow.
