Instructors With Practical Experience
All SRC instructors bring to your classroom an effective combination of experience, formal academic training, and technical expertise. You'll find their presentations interesting, comprehensive, and very easy to understand.

Dr. Philip Goodrum is a scientist with experience in developing and teaching probabilistic modeling approaches for human health risk assessment. He received his Ph.D. from SUNY College of Environmental Science and Forestry (ESF), where the focus of his graduate research was on developing a C++ probabilistic exposure model (the ISE model) for quantifying uncertainty and variability in childhood lead risk assessments.

Dr. Goodrum has applied the ISE model to conduct a quantitative uncertainty analysis of lead risks at six Superfund sites in EPA Regions 3 and 8. He has also developed a spreadsheet probabilistic model for quantifying variability in the bioavailability of lead in adults as a function of temporal patterns in exposure and meal times.

Dr. Goodrum has presented short courses on the uses and limitations of Monte Carlo analysis in risk assessment to federal and state agencies. In FY2000, Dr. Goodrum will teach a training course in probabilistic risk assessment to risk assessors in each of the ten regional offices of the EPA. In addition, he is currently assisting a group within the EPA to develop guidance on the use of probabilistic analysis in human health and ecological risk assessment.

Dr. D. Anthony Gray has served as a task and contract manager on numerous projects for more than 20 years at SRC. In this capacity, he has directed the development of more than 500 documents that assess the environmental fate and exposure potential of both industrial chemicals and pesticides. In addition to assessment projects, Dr. Gray has both directed and participated in a diversity of environmental modeling efforts including those designed to aid in the estimation of risks associated with the transportation of hazardous materials, modeling the fate and transport of chemicals at hazardous waste sites, and modeling the fate of pesticides used by the USDA in pest eradication efforts. He also has directed several data base development projects for the EPA, including the tracking system used by the TSCA Interagency Testing Committee. Furthermore, Dr. Gray is actively participating in a program to help verify compliance with the international treaty to ban chemical weapons.

Dr. Phil Howard has been involved in the collection and evaluation of environmental fate data for more than 30 years. For the last 20 years, he has directed the design and maintenance of the SRC Environmental Fate Database (EFDB), which is supported by the U.S. EPA. He has also directed the information evaluation and peer review of the Environmental Fate/Exposure section of the National Library of Medicine's (NLM) Hazardous Substance Data Bank (HSDB), where the environmental behavior of more than 1500 chemicals is summarized. In addition, he is Project Director of a contract with the U.S. EPA to review available data registration packages on chemistry and fate of pesticides in the environment to identify any variance from published guidelines/standard evaluation practices/data review guidelines.

Dr. Howard is the editor for the seven book series Handbook of Environmental Fate and Exposure Data for Organics and the Handbook of Environmental Degradation Rates and has published more than 40 journal articles on the environmental fate of commercial chemicals. He is also editor for a Dictionary of Chemical Names and Synonyms and a Handbook of Physical Properties of Organic Chemicals and has been particularly active in the development of methods and software for estimating physical properties and degradation rates.

Mr. William Meylan is Senior Environmental Scientist who has worked with SRC for more than 25 years. He has authored numerous environmental profiles for the National Library of Medicine's Hazardous Substances Data Bank and co-authored many Health and Environmental Effects Documents for the U.S. EPA.

For the past 13 years, Mr. Meylan has been involved in the development of methodology and computer software to predict physical and chemical properties of organic compounds for assessment of environmental fate and transport. He is the author of nearly a dozen scientific journal articles that describe chemical structure estimation methodologies and is the co-author of two books, "Handbook of Environmental degradation Rates" (Lewis Publishers) and "Handbook of Physical Properties of Organic Compounds" (CRC Press). He is also the contributing author to about half a dozen other publications.

Dr. Jay Tunkel is Contract Manager/Senior Scientist in the Environmental Science Center with extensive experience in the abiotic degradation of organic compounds. A major area of his research interests involves the identification of substitute chemicals that do not contribute to global warming or the depletion of stratospheric ozone, using atmospheric fate and structure/activity relationships. Current research includes the development of new methodology for predicting ground-level ozone formation potentials.
