Portrait of Henry Schellhorn

Henry Schellhorn is an associate professor of mathematics at Claremont Graduate University’s Institute of Mathematics Sciences and academic director of the Financial Engineering Program at the Drucker School of Management. His research focuses in the areas of Monte Carlo simulation, credit risk management, interest rate models, queuing theory, and combinatorial auctions.

Schellhorn joined the CGU faculty in fall 2005. Previously a faculty member at the University of Lausanne in Switzerland, Schellhorn created an exchange program between the Drucker School’s Financial Engineering program and the University of Lausanne in 2006.

Before joining CGU, Schellhorn worked as a quantitative analyst in private industry and as a principal research engineer at Oracle Corporation. There, he headed a research group that developed a system for using Monte Carlo simulations to calibrate Value at Risk models. He currently holds a U.S. patent for the procedure (U.S. Patent 7010510, Variance Reduction Technique for Large Scale Risk Management). Recently, Schellhorn ran an Engineering and Industrial Applied Mathematics Clinic, where he worked with students to develop new approaches to assessing credit risk.

In addition to publishing regularly in journals, Schellhorn has served as an associate editor for the Journal of Applied Mathematics and Decision Sciences and as referee on several other prestigious finance, mathematics, and operations research publications. He has organized or co-organized symposiums on a range of topics, including Interest Derivatives, Energy and Energy Derivatives, and Financial Mathematics.

Schellhorn’s research has received funding from Swiss National Research Fund, Fair Isaac Company, Fitch Ratings, and more, and he has been the recipient of Best Paper Awards from the International Business Economics Research Meeting and the World Congress on Engineering and Computer Science. In addition, he has given many invited talks, including at The Capital Group, USC, the Monte Carlo I.M.A.C.S. Conference, and the Society of Actuaries Interest Rate Conference.
