Patrick Breysse, PhD, CIH.


Joined CDC in December 2014 as the Director of NCEH/ATSDR. Dr. Breysse leads CDC’s efforts to investigate the relationship between environmental factors and health. He came to CDC from the Johns Hopkins University where he served as Associate Chair for Educational Programs within the Department of Environmental Health Sciences, Program Director for the Industrial Hygiene Training Program, and co-director of the Johns Hopkins Center for Childhood Asthma in the Urban Environment.

During his 30 years at Johns Hopkins, Dr. Breysse established a long-standing expertise in environmental health as well as a strong record as a leader in the field. He has published over 242 peer-reviewed journal articles and has presented at more than 25 scientific meetings in just the past 5 years. His research has focused on the evaluation and control of chemical, biological, and physical factors that can affect health, with a particular concentration on risk and exposure assessment.

Dr. Breysse received his PhD in Environmental Health Engineering from Johns Hopkins University in 1985 and completed postdoctoral training at the British Institute for Occupational Medicine in Edinburgh, Scotland. He is also a board certified Industrial Hygienist and an editorial review board member for the Journal of Exposure Science and Environmental Epidemiology.

Jack de Bruijn

He is a chemist by training and has a PhD in environmental toxicology.



Dr. Antonia Calafat is the Chief of the Organic Analytical Toxicology Branch, Division of Laboratory Sciences, National Center for Environmental Health, U.S. Centers for Disease Control and Prevention (CDC) in Atlanta, Georgia. She leads CDC's biomonitoring programs for assessing human exposure to pesticides; flame retardants; polycyclic aromatic hydrocarbons; chemicals added to consumer and personal-care products such as phthalates and phenols; and persistent organic pollutants including polybrominated diphenyl ethers; polychlorinated dibenzo-p-dioxins, furans, and biphenyls; and per- and polyfluoroalkyl substances (PFAS).

She has developed and maintained extensive collaborative research with leading scientists in the fields of exposure science, epidemiology, toxicology and health assessment, and has published over 460 peer-reviewed articles. Her research has made important contributions to biomonitoring science, including CDC's National Reports on Human Exposure to Environmental Chemicals.

Throughout her career, Dr. Calafat has served on numerous advisory committees and scientific panels. She was the vice-chairperson at the 2010 FAO/WHO Expert Meeting to assess the safety of bisphenol A. She serves as co-chair of the U.S. Association of Public Health Laboratories’ National Biomonitoring Network Steering Committee to establish a national network of public health laboratories for state-based environmental health surveillance. She also serves on the Advisory Board of the Human Biomonitoring for the European Union (HBM4EU, a joint effort of 28 countries, the European Environment Agency, and the European Commission). Since 2017, she is the co-Editor-in-Chief of the International Journal of Hygiene and Environmental Health.

Dr. Calafat earned her PhD in Chemistry in 1989 from the University of the Balearic Islands, Spain. She was a Fulbright Scholar at the Department of Chemistry of Emory University where she completed her postdoctoral training. She joined CDC in 1996.

Mar Gonzalez

Administrator, Environment Directorate, Organisation for Economic Cooperation and Development.

Mar Gonzalez joined the Organisation for Economic Co-operation and Development (OECD) in 2004 to work in its Environment, Health and Safety Division. Over the years, she has had a number of responsibilities under the heading of safety/ risk assessment and international harmonisation in the regulation of chemicals and products of modern biotechnology. Since she joined OECD, she has been involved in various technical programmes covering biosafety, the safety of novel foods and feeds and chemical accident prevention, preparedness and response. She was involved in the establishment of the programme on Nanosafety in 2006 and has since been responsible for the implementation of its programme of work, which includes the development of tools for assessing the hazards of nanomaterials such as the development of OECD Test Guidelines and guidance documents. In 2010, she became responsible for the outreach work on chemicals, as well as reviewing the legal frameworks of non-OECD countries seeking a partnership at OECD. Mar has a BA in Physical Anthropology, a Master degree in Biotechnology and Ethics from the University of Sheffield, UK and a Diploma on Biosafety.

Marcelo Korc, PhD.


Dr. Korc is the Unit Chief, Climate Change and Environmental Determinants of Health at Pan American Health Organization, the regional office of the World Health Organization. He has been a regional advisor with PAHO/WHO since 1998. Currently, he has the responsibility of developing the regional cooperation program on environmental determinants of health, climate change for the Region of the Americas. Prior, Dr. Korc provided policy and technical advice to senior government officials on health and human security, environmental health, social health determinants, violence prevention, and healthy settings in the U.S.-Mexico border region, Colombia, Peru, and Venezuela.

Dr. Korc received a B.Sc. in Chemical Engineering (Cum Laude) from the Technion-Israel Institute of Technology in 1987, a Ph.D. in Chemical Engineering from the University of Rochester in New York in 1992, and a master’s in public health from the University of Texas in 2011. He was an American Association for the Advancement of Science Fellow in 1994 and received the Sandy Tyler Endowed Fellowship‏ in Health Sciences in 2011.

Jeffrey T. Morris, PhD

Office of Pollution Prevention and Toxics (OPPT) Environmental Protection Agency

Jeffery Morris is Director of the United States Environmental Protection Agency’s Office of Pollution Prevention and Toxics (OPPT), which regulates industrial chemicals under the Toxic Substances Control Act as well as administers the Pollution Prevention Act and the Toxics Release Inventory. In his 27-year career at EPA, Jeff has held several positions in OPPT, the Office of Research and Development, and the Office of Pesticide Programs.

Joel Schwartz


Dr. Joel Schwartz is a Professor in the Departments of Epidemiology and Environmental Health at the Harvard School of Public Health, and in the Department of Medicine at Harvard Medical School. He is also a faculty member in the Environmental Biostatistics Program at the School of Public Health. Dr. Schwartz received his B.A. (1969) and Ph.D. (1980) from Brandeis University.

He is a member of the International Society for Environmental Epidemiology, and the American Thoracic Society. Dr. Schwartz served as a member of the Center for Disease Control’s Committee on Preventing Childhood Lead Poisoning from 1994 to 2002, and as a member of two National Research Council Committees (Committee on Assessing Lead Exposure in Critical Populations, Committee on Environmental Epidemiology).

Dr. Schwartz was a recipient of a John D. and Catherine T. MacArthur Fellowship, and a World Congress Award from the International Union of Environmental Protection Associations. His expertise is in epidemiology, biostatistics, and cost benefit analysis. Dr. Schwartz’s major subject matters include air pollution and lead. His research has involved cross-sectional, time-series, cohort and panel studies of the acute and chronic health effects of air pollution, including both respiratory and cardiovascular endpoints, and he has a particular interest in questions of susceptibility.

In the last two years, Dr. Schwartz received funding from the National Institutes for Health (NIH) for environmental biostatistics, for studies of aeroallergen exposure and asthma, for studies of lead, for a study of the association between particulate air pollution and heart attacks, and for a study of socioeconomic gradients in breast cancer. He has received funding from EPA as the PI for Epidemiology of the Harvard PM Research Center, and from the Health Effects Institute (HEI) for the APHENA project, which aims to combine North American and European time series analyses of air pollution, morbidity, and mortality.
