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. Major national projects like NASA's Space Station, Mars Rover and the GPS Satellite System have adopted his theories, and several IEEE computer standards incorporate Lehoczky’s work

After earning his PhD from Stanford University, Lehoczky joined the statistics department at CMU in 1969. He is a well known for his application of stochastic modeling to problems in finance, which 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. Lehoczky served as the head of the Department of Statistics from 1984 to1995 and has led the College of Humanities and Social Sciences (H&SS) since 2000. During his tenure as H&SS Dean, Lehoczky has overseen the launch of the college’s ambitious Humanities Initiative, which created the Humanities Scholars Program, the Humanities Center and the Center for the Arts in Society. He is also responsible for fostering H&SS research in the brain sciences and has been a strong advocate for developing CMU international programs, such as the Center for International Relations and Politics.  

Lehoczky is a fellow of the American Statistical Association, the Institute of Mathematical Sciences, INFORMS and the American Association for the Advancement of Science and is an elected member of the International Statistics Institute.
