About the Dean: John Lehoczky

With his experience in interdisciplinary research and education—the heart of a liberal arts education—John Lehoczky is leading Carnegie Mellon University's College of Humanities and Social Sciences (H&SS) into the 21st century. 

Lehoczky sees H&SS as a college that is "developing novel research projects and education programs in the social sciences and humanities that will enhance Carnegie Mellon's reputation as a great university." 

In his own research, Lehoczky, the Thomas Lord Professor of Statistics, studies stochastic processes and how they can be used to model real applications. His investigation into the evolution of random processes over time is focused on developing methods that combine system scheduling with performance evaluation and can be applied to manufacturing systems in which products have delivery deadlines. His theories can also be applied to real-time computer or communication systems that require certain tasks to be completed within stringent timing requirements. 

Lehoczky collaborates with faculty and graduate students from Carnegie Mellon's Department of Electrical and Computer Engineering, the School of Computer Science and the Software Engineering Institute, and they have been able to build and test systems that embody Lehoczky's research. International projects like NASA's Space Station and Mars Rover and the GPS Satellite System have adopted his theories, and several IEEE computer standards incorporate his work.

Lehoczky is also well known for his application of stochastic modeling to problems in finance. Working with colleagues in Carnegie Mellon's Department of Mathematics, he developed equilibrium-based models for stock and bond prices. He also conducts research of the use of Monte Carlo simulation methods for pricing financial instruments. 

This research initiative in finance has also led to the creation of a unique master's degree program in computational finance involving the Department of Statistics, the Department of Mathematical Sciences, the David A. Tepper School of Business, and the H. John Heinz III School of Public Policy and Management. The program was created to provide strong quantitative training specifically designed for students preparing for careers on Wall Street and in the financial services industry. Lehoczky was one of the founders of this program and continues to serve on its steering committee.  

Lehoczky also has collaborated on projects in the medical sciences, including one at the University of Pittsburgh medical school, to better understand how biological rhythms, subject activity and treatments affect a patient's blood pressure. He is also a fellow of both the American Statistical Association and the Institute of Mathematical Statistics and is an elected member of the International Statistics Institute. Lehoczky received his undergraduate degree in mathematics from Oberlin College and his master's and doctor's degrees in statistics from Stanford University. He joined the Carnegie Mellon faculty in 1969, was named professor of statistics in 1980 and professor of statistics and mathematics in 1988.
