Dr. Dave Ludwig is from a family of educators and taught his first course--high school biology--fresh out of Rutgers. In a long career since that has taken him on research and consulting assignments around the world, he has continued to teach at every opportunity and in every possible forum. He has taught varied subjects in many contexts, from informal lessons in field biology and ornithology to short courses in ecosystems sustainability at technical conferences and AEHS-sponsored specialty classes in risk assessment and environmental restoration at the Kuwait Foundation for the Advancement of Science. In 2009 he was engaged by the University of Maryland College Park to develop curriculum for and teach the premier edition of a departmental core course in Ecological Risk Assessment. That course provides the foundation on which the AEHS course is based. 

Ioana G. Petrisor, Ph.D. in an environmental biochemist with 18 years of experience (both in academia and industry). She is currently Editor-in-Chief of Environmental Forensics Journal and Senior Scientist at Haley & Aldrich, Inc. a consulting firm promoting environmental sustainability. Dr. Petrisor specializes in environmental forensics/litigation support using advanced fingerprinting methods to track the source and age of contaminants. She conducted innovative research for US DOE, US DoD and European Community on environmental characterization and development of innovative remedial technologies (e.g., bioremediation, phytostabilization, use of bioproducts) for a variety of contaminants in soil, aquatic sediments, and water. Dr. Petrisor is author of an invention patent, a forensic text book (in press) and more than 70 scientific publications and 12 editorials. She has a PhD in Biology/Biochemistry from Romanian Academy of Sciences and a Bachelor in Chemistry/Biochemistry from Bucharest University, Romania.

Dr. Paolo Ricci has led and conducted qualitative and quantitative analyses and experimental work, for approximately 30 years, in the USA, Canada, Italy, Australia, France, Vietnam, China, and the European Union. For example, he has worked on: probabilistic decision models applied to environmental and energy choices, technological diffusion and innovation, probabilistic causation, linear and non-linear applied statistical models, deterministic and probabilistic systems analysis, as well as at the intersection between science and law via causal analysis. He also has studied the human health risks from nuclear and non-nuclear energy technologies, from the cradle to the grave, cancer and other toxic effects from exposure to airborne and waterborne contaminants and microbiological agents. Dr. Ricci has been the Head of the Technology Clearinghouse of the IEA/OECD (full diplomatic status). Most of this work has been published in major journals and books with hundreds of scientific and legal citations to his published work. In the last four years, he has served as a peer reviewer of the United States Department of Energy (DOE) activities regarding the human health risks from past nuclear and thermonuclear tests at the Nevada Test Site, and in the reviews of other DOE activities at their facilities, including Hanford nuclear reactor sites. Dr Ricci is a Fulbright expert (specialist in environmental health, risk assessment and management) on a five-year term that started in 2010. He is an Honorary Professor, University of Queensland, NRCET, Brisbane, Australia; Adjunct Professor School of Public Health, University of Massachusetts, Amherst, MA, Guest Professor at Xiamen University PRC, and Professor of Business and Decision Analysis at Holy Names University, Oakland. He has been teaching graduate courses in epidemiology, risk assessment and management, decision analysis and applied economics in Australia, Canada, Thailand, Italy, Philippines, China, Hungary and several other countries. Dr. Ricci has been Associate Professor at Stanford University and at UCLA (School of Public Health), as well as Adjunct Full Professor of Law at UC Berkeley. From 1994 to 2000, he was Associate Professor (equivalent to US Professor) of Public Health and Head of the Risk Analysis Unit (NSW Department of Health, Sydney), as well as Professor (equivalent to US Professor with Chair) at the University of Wollongong (Faculty of Law), Australia; he has also been Faculty Scholar at Lawrence Livermore National Laboratory.

Dr. Jason White is currently Chief Scientist of the Department of Analytical Chemistry at the Connecticut Agricultural Experiment Station.  He received a B.S. in Ecology from Juniata College in Huntingdon, PA in 1992 and his Ph.D. in Environmental Toxicology from Cornell University in 1997.  Dr. White completed a one year post-doctoral position at the Connecticut Agricultural Experiment Station in New Haven CT from 1997-1998 in the Department of Soil and Water before joing the Station full time.  Dr. White holds secondary affiliations as a Research Associate within the Environmental Engineering Program at Yale University, an Adjunct Professor in the Department of Biology and Environmental Science at the University of New Haven, and an Adjunct Professor of Biology at Quinnipiac University. He is Managing Editor for the International Journal of Phytoremediation, Executive Vice President of the International Phytotechnology Society and on the editorial board of Environmental Toxicology and Chemistry, as well as Environmental Pollution. Dr. White has active research programs focused on the impact of nanoparticles on agricultural plants and on the phytoremediation of persistent organic pollutants in soil. He lives in Prospect CT with his wife and six children (ages 2-16).
