This three-day workshop is intended to identify methods to satisfy an
unmet need in human health risk assessment, estimating responses at low
doses.  Most current assessments use some kind of upper bound on
response.  Such estimates are useful for many purposes, but sometimes an
unbiased estimate is needed.  The organizers (primarily James D. Wilson
of Resources for the Future and Annie Jarabek of the U.S. Environmental
Protection Agency) suggest that approaches based on Bayesian logic may
lead to low-dose estimates of response and offer the workshop to explore
this possibility.  The workshop will begin with an introduction to
Bayesian analysis, for persons unfamiliar with the methods, and will
cover applications of Bayesian methods in medical research, space
exploration, exposure assessment, and ecological risk.  The workshop
will explore the use of Bayesian methods in modeling dose-response
relationships and integrating disparate data in dose-response
estimation.  It will conclude with discussion of future directions and
research needs.
