Dr. Gary Witt returns to the Fox School on a non-tenure-track appointment within the Department of Statistical Science. He previously served the Finance and Statistics departments as a full-time non-tenure track faculty member from 2008-2015, before accepting a similar position at Syracuse University.
Prior to his pedagogical career, Witt pursued a 20-year career in finance in New York and London in derivatives, structured finance, and investment management, which includes a term as managing director at Moody’s Investors Service. He drew from his many years of experience to teach statistics and finance at the Fox School, where he worked to incorporate tenets of environmental sustainability into his business curriculum.
Witt received his PhD in Statistics from the Wharton School at the University of Pennsylvania. He also studied at Southern Methodist University, where he earned a Bachelor of Science degree in Economics and Bachelor of Arts degrees in Mathematics and Physics.
