policy and decision making under conditions of risk and uncertainty. Dr. Arvai received a B.Sc.
in Biology (1994), an M.Sc. in Marine Ecology/Oceanography (1997), and a Ph.D. in Decision
Science (2001) from the University of British Columbia (Vancouver, B.C., Canada). Dr. Arvai
is also an adjunct professor in the Institute for Resources, Environment, and Sustainability at the
University of British Columbia and one of the principal investigators at Decision Research based
in Eugene, OR. Dr. Arvai's research focuses on problems related to environmental decision
making, mainly in the context of designing and testing decision-aiding approaches for risk and
resource management, as well as choice and preference behavior. Dr. Arvai has an extensive
background in marine biology and ecology. He has conducted research on the ecological effects
of various contaminants (e.g., metals, organics) in coastal estuaries. He has also worked on
experiments, conducted in cooperation with the Canadian Space Agency and National
Aeronautics and Space Administration (NASA), to determine the drivers for vertical migration in
shallow-system copepods. Dr. Arvai also has experience in psychology and economics; to this
end, much of Dr. Arvai's current is in decision sciences and is applied mainly to the broader
context of natural resource management. This research involved studies of choice and
preference behavior, along with tests of prescriptive, structured decision making approaches for
making multiattribute, values-based choices and for fostering more thoughtful tradeoffs in
resource management. Publications stemming from his research appear in journals such as
Environmental Science & Technology, Risk Analysis, the Journal of Forestry, Ecological
Economics, and Climatic Change. Dr. Arvai was previously on the faculty of the School of
Natural Resources at the Ohio State University where he conducted research focusing on
developing improved decision making approaches for risk problems involving intertemporal
tradeoffs (i.e., management effort expended now in return for potential benefits later). He moved
to Michigan State to take part in the development of a new program in environmental science
and policy. Dr. Arvai is a member of the Society for Risk Analysis, Society for Judgment and
Decision Making, and Sigma Xi. Recent sources of research funding include the National

and an M.S. in environmental chemistry and B.S. in Crop and Soil Science from the Michigan
State University. He is senior author on a widely used textbook, Soils and Environmental Quality
(third edition). His research program has three main thrusts: 1) Trace element chemistry and
contamination in soils. He has researched revegetation strategies for contaminated sites,
including the use of soil amendments to reduce phytotoxicity and innovative approaches to
establish vegetation such as deep-planted poplar trees or mycorrhizae inoculation. He has
assessed novel approaches for estimating trace element bioavailability using physiologically
based extraction tests simulating the human digestive process, animal feeding, and diffusive
gradients in thin films. He has contributed some of the original research on in situ remediation of
lead contaminated soils, resulting in a patent. 2) Impacts of agriculture on water quality. He has
quantified the changes in total and soluble phosphorus losses in runoff that can be realized by
changes in tillage and phosphorus fertilizer management and has provided guidance on critical
soil phosphorus levels in relation to water quality, including providing advice to state and federal
agencies on legislation and the development of the phosphorus site index for Kansas. Current
work emphasizes the combined effect of best management practices on multiple water
contaminants and the use of animal manures as nutrient sources. Additional research has
investigated techniques for estimating phosphorus bioavailability in soil and water including
development of a procedure using iron-oxide as a phosphorus adsorbent. 3) Nutrient cycling in
concentrated animal feeding operations. Dr. Pierzynski and co-workers have characterized the
extent of soil contamination beneath lagoons and conducted basic ternary cation exchange work
on lagoon liner materials with a focus on the development of soil chemical criteria for lagoon
liner construction that will minimize losses to the environment. Dr. Pierzynski's record of

Committee on Evaluation of the Veterans Administration's Presumptive Disability Decision-
Making Process. Dr. Vedal's research interests are in the health effects of air pollution and in
occupational lung disease. He is currently working on incorporating source-oriented approaches
to specifying exposure to ambient air pollution in epidemiological studies, and on identifying
effects of long-term exposure to components and sources of particulate matter on cardiovascular
disease.

Division). She received her bachelor's degree from Cornell University, and M.S. and Ph.D. from
New York University. Dr. Weis' research has focused on estuarine ecology and ecotoxicology.
She has published over 150 refereed papers, focusing mainly on stresses in the estuarine
environment, and their effects on organisms, populations and communities. Particular areas of
focus have been effects of metal contaminants on growth, development, and behavior;
development of tolerance to contaminants in populations living in contaminated areas; effects of
invasive marsh plant species on estuarine ecology and on fate of metal contaminants. Much of
her research has been focused on estuaries in the New York/New jersey Harbor area. Dr. Weiss
has served on numerous advisory committees and has held leadership positions: Boards of
Directors of the Society of Environmental Toxicology and Chemistry (SET AC) and the
American Institute of Biological Sciences (AIBS); Chair of the Biology Section of American
Association for the Advancement of Science (AAAS) in 2000; and President of AIBS in 2001.
She is currently Board member of the Association for Women in Science (AWIS). She is a
fellow of the American Association for the Advancement of Science (AAAS). She has served on
advisory committees for the U.S. EPA Scientific and Technical Achievement Awards (STAA)
for the U.S. EPA Science Advisory Board, and the Endocrine Disruptors Screening and Testing
Advisory Committee - EDSTAC) and for the National Oceanic and Atmospheric Administration
(NOAA). She has been a member of the Marine Board of the National Research Council, and
currently serves on the National Sea Grant Review Panel of NOAA. Dr. Weis has previously on
the Editorial Boards of Transactions of the American Fisheries Society and Bulletin of
Environmental Contamination and Toxicology. She is Currently Associate Editor of Bulletin of
Environmental Contamination and Toxicology and on the Editorial Board of Bioscience. Dr.
