Lisa_BaxterLisa Baxter, Sc.D.
Dr. Baxter is currently a Research Environmental Health Scientist in the National Exposure Research Laboratory at the U.S. EPA. She earned her Sc.D. in Environmental Health from the Harvard School of Public Health. Her primary research focus has been on the evaluation and integration of exposure models in order to improve human exposure estimates for air pollution epidemiology studies. This has included developing and applying new techniques and approaches for studying and resolving critical human exposure assessment problems. She has developed and evaluated approaches for estimating exposure to air pollution for epidemiological studies at the local, city, and national level. She has also investigated the role of exposure error in both single pollutant and multipollutant settings.

Brian Curwin has worked in the field of exposure assessment for over 20 years. Currently he is a Senior Research Fellow and Deputy Branch Chief of the Industrywide Studies Branch, Division of Surveillance, Hazard Evaluations, and Field Studies, in the National Institute for Occupational Safety and Health. He has conducted several studies assessing occupational exposure to pesticides, including investigations of take-home pesticide exposure among farmers and their families, and pesticide exposure among tobacco harvesters; to nano-sized metal oxide particles in manufacturing; and to diacetyl and other chemicals in the flavoring and food production industries. Currently, he is the principle investigator of a study assessing exposure to pesticides among sugarcane workers in Central America. Prior to coming to NIOSH in April 2000, Dr. Curwin worked as a regulatory scientist for 5 years conducting occupational pesticide exposure assessments for the Pest Management Regulatory Agency of Health Canada.

Dr. Curwin received a Master of Science degree in occupational health from McGill University, Montreal, Canada in 1994 and his Doctorate degree in exposure assessment from Utrecht University, Utrecht, Netherlands in 2006. He has presented at numerous ISES conferences, and has published numerous papers in peer reviewed journals including the Journal of Exposure Science and Environmental Epidemiology.  Mr. Curwin has received the U.S. Civil Service Special Act Award (2002), the U.S. Department of Health and Human Services Secretary’s Award for Distinguished Service (2002), the Treasury Board of Canada Award of Excellence (1999) and the Health Canada Departmental Award of Merit (1998).  He has also been nominated for the Charles C. Sheppard Science Award for Outstanding Peer Reviewed Research Papers (2003) and received an Alice Hamilton Award honorable mention for Excellence in Occupational Safety and Health (2007), and a Bullard-Sherwood Award for Research to Practice, Knowledge Category (2011).

Dr. Curwin has been an active member of ISES since 1997. He was a councillor representing the government sector on the ISES board 2009-2011, was the chair of the ISES board Nominations Committee from 2010-2015, was on the technical organizing committee for ISES 2011, 2014, 2015 annual meetings, and was the co-chair of ISES 2012 annual meeting.
Dan_ValleroDaniel Vallero, Ph.D.
For nearly four decades, Daniel Vallero has conducted research, advised regulators and policy makers, and worked to advance the state-of-the-science of human and ecosystem exposures, including both measurement and modeling. Since 1976, he has worked in some of the most important U.S. Environmental Protection Agency programs, including global scale atmospheric problems, ecosystem response to climate change and acid rain, and human exposure to manufactured chemicals.

As adjunct professor at Duke University, he has led the Engineering Ethics program, a popular and innovative program that introduces students to the complex relationships between professional, scientific, technological and societal demands on the engineer. He teaches courses in air pollution, sustainable design and green engineering, and ethics. In addition to ISES’s Government Councilor, Dr, Vallero sits on the editorial board of the journal, Process Safety and Environmental Protection, is a consulting editor for environmental engineering to the McGrawHill Yearbook of Science and Technology and the Encyclopedia of Science and Technology, is a referee for numerous scientific and engineering journals, and is guest editor of Ethics in Biology, Engineering and Medicine. He was nominated for the 2014 World Technology Award (Ethics), has been an advisor to the National Academy of Engineering's Online Ethics Committee, and was elected to the Executive Board of the National Institute of Engineering Ethics. His articles appear in encyclopedias, handbooks and engineering manuals. His most recent of twelve books is the fifth edition of Fundamentals of Air Pollution. His books address pollution engineering, environmental disasters, biotechnology, green engineering, life cycle analysis and waste management. His research appears in the Journal of Exposure Science and Environmental Epidemiology and other major, peer-reviewed journals.

Dr. Vallero holds a Ph.D. in Civil and Environmental Engineering from Duke University, Masters in Environmental Health Sciences (Civil and Environmental Engineering) from the University of Kansas, Masters in City and Regional Planning from Southern Illinois University, and a Bachelors Degree in Earth Sciences and Psychology from Southern Illinois University.
