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.

Happily Hopeless: Professor George Loewenstein Discovers Optimism Can Be Detrimental to Mental Health
New research by Social and Decision Sciences Professor George Loewenstein and Dylan M. Smith, Aleksandra Jankovic and Peter A. Ubel of the University of Michigan shows that holding on to hope may not make patients happier as they deal with chronic illness or disease. The study tracked and surveyed patients with both reversible and irreversible colostomies over a six-month period to measure their emotional well-being. The results confirm that people do not adapt well to situations if they're believed to be short-term. Read more... |

H&SS Researchers Develop Novel Tool To Rank Death Rates
Have you ever wondered what the odds are that you may die in the next year? Would it be from illness or an accident? Is it something you can control? Or is it completely out of your hands? A new Web site, www.DeathRiskRankings.com, developed by researchers and students at Carnegie Mellon University, allows users to query publicly available data from the United States and Europe, and compare mortality risks by gender, age, cause of death and geographic region. Paul Fischbeck, a professor of social and decision sciences and engineering and public policy led the development team. Read more... |
