Biography

Professor Jeff Stuart teaches mathematics and statistics for the Mathematics Department. He developed and directs the Department’s undergraduate major in financial mathematics. He helped develop the new CFA-oriented Masters in Finance degree program in the PLU School of Business, and he teaches several courses for the program. In addition to teaching a variety of courses, he has supervised over forty senior theses and masters projects in pure and applied mathematics, statistics and finance.

Professor Stuart obtained bachelors degrees in mathematics and physics from Pomona College. Subsequently, he earned an M.S. and a Ph.D. in mathematics from the real UW — the University of Wisconsin at Madison. His mathematics research interests lie at the intersection of graph theory, matrix theory and combinatorics. In addition, he has published work in optimization, statistics and finance. His finance interests include financial asset valuation modeling and the unintended consequences of management and regulatory policy. He has authored more than seventy research and expository articles, and he has given more than 100 seminar and conference presentations.

Prior to arriving at PLU in 2001, Professor Stuart spent 14 years at the University of Southern Mississippi, where he was a tenured full professor, teaching both undergraduate and graduate courses in mathematics and statistics.  In his not-so-copious spare time, Professor Stuart sings chamber music, cooks Mediterranean food, hikes, and herds cats.
