Introduction
I am a Professor in the Departments of Biological Statistics and
Computational Biology (BSCB) and Statistical Science at Cornell University.
I am also a Professor of Biostatistics in the
Department of
Public Health at Weill-Cornell Medical College,
located in NYC.
I graduated
in 1988 with a BA in Mathematics
from Rutgers College,
the main undergraduate college of Rutgers University prior to its
restructuring as part of the new School of Arts and Sciences. I
earned both my masters and doctoral degrees in Biostatistics at Harvard
University.
Before coming to Cornell, I was a faculty member in the Department of Biostatistics
at the University of Michigan.
I am part of a family tradition in statistics: my father
is a Professor of Statistics at
Rutgers, and my wife is a consulting statistician in
the
Division of Nutritional Sciences.
One of my major research areas is survival analysis, with a focus on
problems involving recurrent event data and risk prediction. More
generally, I am interested in statistical inference for point process
data; outcome prediction in medicine, epidemiology and public health;
evaluating the cost and quality of health care; demography and
population studies; asymptotics (theory and approximation); and,
various problems in statistical computing. Recently, my students have
worked on computational methods for analyzing high dimensional
datasets, various extensions of the semiparametric
accelerated failure time model and related estimation methods,
Bayesian approaches to the semiparametric proportional
hazards model, GEE methods for recurrent event data, models for
correlated bivariate point processes, and various other problems. I
am currently (or have recently) engaged in a variety of collaborative
activities, including cardiology, cancer risk prediction, health
services research, social science research in public health and
nutrition, watershed modeling, genomics, genetic epidemiology, and
veterinary medicine. I am presently involved in the Cornell Population Center (CPC)
as the director of its statistics core. The CPP is an
interdisciplinary group of Cornell researchers with interests in
demography and population research.
In terms of noteworthy professional and university-level activities, I
have continuously served as an Associate Editor for JASA (Theory &
Methods) since 1997. I also serve as an Associate Editor for The Electronic Journal of
Statistics and previously as a moderator for arXiv ( stat.TH). I am a Fellow of the ASA,
Fellow of the IMS,
being a longtime member of these professional societies as well as ENAR. At Cornell, I am the Director
of Graduate Studies
for the fields of
Statistics and
Biometry.
In addition to these two fields,
I am also a member of the major field
Operations Research and Information Engineering
and minor fields of
Demography
and
Epidemiology.
