Dr. Piegorsch is a Professor of Mathematics, a Professor of Public Health, a Professor of Agricultural & Biosystems Engineering, Director of Statistical Research & Education at the
University's BIO5 Institute, a Member and former Chair of the University’s Graduate
Interdisciplinary Program (GIDP) in Statistics, and he holds accreditation as a
Professional Statistician (PStat) from the American Statistical
Association.  Dr. Piegorsch studies data
science for environmental problems, with emphasis on environmental informatics
and risk assessment.  He coordinates
these interests with his research translating quantitative risk analytics to
problems in public health, including geo-spatially referenced disaster
informatics; statistical data analytics; and multiple/simultaneous inferences
for toxicological and genetic endpoints. He currently leads a team developing
statistical benchmark dose markers in environmental hazard analyses. This
research has been funded by the U.S. National Institute of Environmental Health
Sciences, the U.S. Environmental Protection Agency, and the U.S. National
Cancer Institute. He also has constructed statistical models for data from
transgenic bio-technologies, developed guidelines for the design of bioassays
in select transgenic animal systems, and has proposed retrospective designs for
analyzing gene-environment and gene-nutrient interactions in human population
studies.  Dr. Piegorsch has held a number
of professional positions, including Chairman of the American Statistical
Association Section on Statistics & the Environment (2004); Vice-Chair of
the American Statistical Association Council of Sections Governing Board
(1997-1999), and election to the Council of the International Biometric Society
(2002-2005). Beginning in 2010 he serves as Editor-in-Chief of Environmetrics, the oldest scientific
journal publishing on the development and application of quantitative methods
in the environmental sciences.  He also
has served as Joint-Editor of the Journal
of the American Statistical Association
(Theory & Methods Section), the
flagship journal of the association; as Co-Editor-in-Chief of the Encyclopedia of Environmetrics, a major
reference source by John Wiley & Sons publishing its second edition in 2012;
and as a member of many journal editorial boards, including Environmental and Ecological Statistics,
Environmetrics, Environmental and Molecular Mutagenesis, Mutation Research, the Journal
of the American Statistical Association
, and Biometrics. Dr. Piegorsch has been honored as a Fellow of the
American Statistical Association (1995), a Member (by Election, 1995) of the
International Statistical Institute, and has received the Distinguished
Achievement Medal of the American Statistical Association Section on Statistics
and the Environment (1993), and the University of South Carolina Educational
Foundation Research Award for Science, Mathematics, and Engineering (2000). He
earned his Ph.D. in Statistics at the Biometrics Unit, Cornell University, in
1984, after which he spent nine years as a practicing statistician with the
U.S. National Institutes of Health, and then 13 years as a faculty member with
the Department of Statistics at the University of South Carolina.
