ISES Distinguished Lecturer Program

The ISES Distinguished Lecturer program provided outstanding speakers to promote exposure science to diverse scientific and policy audiences. The program aimed to 1) stimulate interest and recognition of exposure science in academia, industry, and government; 2) attract students to academic programs in exposure science; 3) motivate consensus and encourage dialogue among exposure scientists on the fundamental principles of exposure science; and 4) promote membership and participation in ISES.

Lectures took place in South America, North America, and Europe.

ISES’ Distinguished Lecturers included Dr. Larry L. Needham, Prof. Matti J. Jantunen, Prof. Dr. Cornelius Johannes van Leeuwen, Dr. Paul J. Lioy, and Dr. Jack Spengler.

Dr. Jack Spengler (Term 2009-2011)
Dr. Jack Spengler has been a leading scholar in the field of exposure science for decades, with focus on indoor air quality. He was a founding member of ISES (originally known as ISEA), a Wesolowski Award recipient, served on numerous 
national and international committees addressing indoor air pollution, and one of the most consistent and active voices both exposure assessment and public health implications. More recently, Jack has focused on topics of sustainability and urban design, and continues to address these significant environmental problems with an eye toward minimizing personal exposures to contaminants. Beyond his reputation as a scholar, Jack is involved with teaching and other outreach efforts. He instructs graduate students at the Harvard School of Public Health and directs a highly subscribed continuing education master’s program through the Harvard University Extension School. The latter program includes an active distance learning module, which is one of Jack’s passions.

Dr. Paul J. Lioy (Term 2008-2010)
Dr. Paul J. Lioy was a Professor and Vice Chair, Department of Environmental and Occupational Medicine at UMDNJ-Robert Wood Johnson Medical School, Piscataway, New Jersey, USA. He was Deputy Director for Government Relations at the Environmental and Occupational Health Sciences Institute and was the Director of the Institute's program in Exposure Science. He co-directed the Center for Exposure and Risk Modeling. Dr. Lioy was a member of the U.S. Environmental Protection Agency Science Advisory Board and a member of the Homeland Security Advisory Committee and the asbestos committee. He was a founding member of ISES, served as President, and a Wesolowski Award recipient. He was chair of the NRC's first committee on exposure assessment that published the "White Book" in 1991. He and a team of colleagues completed research projects on the exposure and health effects caused by the World Trade Center aftermath, and he studied biological and chemical agent acute exposure reduction strategies for homeland security and natural disasters. Dr. Lioy was also a part of the National Children's Study Queens Vanguard Center. Paul passed away unexpectedly on July 8, 2015.

Prof. Dr. Cornelius Johannes (Kees) van Leeuwen (Term 2007-2009)
Kees van Leeuwen (1955) is a Principal Scientist at TNO Quality of Life, The Netherlands, and a retired Director of the Institute for Health and Consumer Protection from the European Commission. He started his environmental research career at the University of Utrecht, The Netherlands, and gradually developed into science-policy advice and management of chemicals, health and environment. He has been a member of ISES, the OECD Management Board, the Dutch Health Council and the external science advisory panel of the European and American chemical industry. As education and capacity builder, he has been a prominent speaker during risk assessment courses and is best qualified to speak on risk assessment and management of chemicals, REACH, intelligent testing strategies and quantitative structure activity relationships. He has served as an expert by the OECD, European Union, U.S. Environmental Protection Agency, European Chemical Industry Organization and the Society of Environmental Toxicology and Chemistry. He gave keynote lectures and published over 160 reports and publications and a book on risk assessment of chemicals. 

Prof. Matti J. Jantunen (Term 2006-2008)
Prof. Jantunen, research professor at the Finnish National Public Health Institute – KTL – Department of Environmental Health in Kuopio, Finland, received his MSME in 1972 at the Tampere University of Technology in Finland, MSEE in 1976 and Ph.D. in 1978 at the University of North Carolina/Chapel Hill in the U.S. He is a founding member of the International Society for Indoor Air Quality (ISIAQ) and an active member and former president (2000-2001) of ISES. Prof. Jantunen’s main interests focus on exposures derived from indoor and traffic sources, and exposures and related health risks from fine particulate matter. Prof. Jantunen has served as an expert to the WHO, the EU and the U.S. EPA, and he has been invited to give plenary lectures and keynote talks at numerous conferences. Dr. Jantunen has authored or co-authored more than 400 scientific publications.

Dr. Larry L. Needham (Term 2005-2007)
Dr. Larry Needham was Chief of the Organic Analytical Toxicology Branch in the National Center for Environmental Health of the Centers for Disease Control and Prevention (CDC). His work involved developing and applying analytical methods for assessing human exposures via biomonitoring to environmental chemicals, including persistent organic pollutants (POPs), perfluorinated chemicals, non-persistent organic chemicals (e.g., pesticides, phthalates, alkylphenols, polycyclic aromatic hydrocarbons, phytoestrogens, volatile organic chemicals, chemicals of mass destruction), and heavy metals. His former group was responsible for almost all of the analytical data in CDC’ biannual National Report on Human Exposure to Environmental Chemicals ( In addition, they collaborated with investigators, both domestically and internationally, on epidemiological studies involving the relations between human exposures to environmental chemicals and potential adverse health outcomes. Dr. Needham authored or co-authored more than 400 scientific publications. Dr. Needham was an active member of ISES, former President (2003-2004), and a Wesolowski Award recipient (2006). In addition to ISES, he was a permanent member of the annual Dioxin meeting’s international advisory Board and editor of Chemosphere: Persistent Organic Pollutants and Dioxins. He consulted with many groups, including the National Academy of Sciences, U.S. EPA, and Health Effects Research Institute. Dr. Needham received his BS from Middle Tennessee State University in 1968 and his Ph.D. from the University of Georgia in 1972. Larry passed away on October 23, 2010.
