Shoji F. Nakayama, MD, PhD

Dr Shoji Nakayama is an MD and holds PhD in public health. His expertise is in exposure science, especially in children’s exposure. He is certified as a Public Health Specialist/Supervisor by Japan Board of Public Health and Social Medicine. He is an associate editor of the Journal of Exposure Science and Environmental Epidemiology.

In 2005, Dr Nakayama was invited to the U.S. EPA and worked on exposure research on perfluorinated substances. In 2009, he moved to EPA’s engineering laboratory to help risk management of the emerging contaminants. Then in 2011, Dr Nakayama joined the National Institute for Environmental Studies in Japan. Currently he is Head of the Exposure Dynamic Research Section as well as Adjunct Professor of the University of Tsukuba, Japan and Mahidol University, Thailand.

Dr Nakayama is a lead exposure scientist for the Japan Environment and Children’s Study (JECS), which is a longitudinal birth cohort study involving 100,000 mothers and children. He is devoted to human biomonitoring research including method development for contaminants of emerging concern. He collaborates with US, Canada, EU and Asian researchers to advance and promote children’s environmental health research.


Pertti (Bert) Hakkinen, Ph.D.

I joined ISEA almost as soon as it started in the 1980’s and have continued to have a strong interest in exposure science as my career has progressed. This includes working at the Oak Ridge National Laboratory in the U.S., at the Procter & Gamble Company in the U.S. and Japan, at the European Commission in Italy, and now at the U.S. National Institutes of Health. Exposure assessors and others internationally need to be able to find, access, learn how to use, and communicate exposure-related information. I keep this in mind during my involvement in enhancing and developing databases, co-authoring publications such as recent ones on a) Exploring Global Exposure Factors Resources for Use in Consumer Exposure Assessmentsand b) New Studies About Everyday Types of Chemical Exposures: What Readers Should Consider, and in my teaching efforts. As a Councilor, I will seek to enhance the efforts of this Society to have its members be able to find, access, learn how to use, and communicate exposure-related information. I am the Acting Head of the Office of Clinical Toxicology in the Division of Specialized Information Services of the National Institutes of Health’s National Library of Medicine. My job includes providing leadership in the development of new resources in exposure science, toxicology, risk assessment, and risk communication, and enhancements to existing resources in these fields. In addition, I am the project leader for the Chemical Hazards Emergency Medical Management (CHEMM) tool. Also, I am an Adjunct Associate Professor in Preventive Medicine & Biostatistics in the F. Edward Hébert School of Medicine at the Uniformed Services University of the Health Sciences (USU) in Bethesda and a co-leader of the Environmental Health Sciences graduate level course offered by the Foundation for Advanced Education in the Sciences (FAES) at the NIH. I earned a B.A. in Biochemistry and Molecular Biology from the University of California, Santa Barbara, and received a Ph.D. in Comparative Pharmacology and Toxicology from the University of California, San Francisco. I am also a member of the Society of Toxicology and a Fellow of the Society for Risk Analysis.


Marsha Morgan, Ph.D.

Dr. Morgan is currently a Research Environmental Health Scientist in the US EPA’s National Exposure Research Laboratory in RTP, NC. She earned her Ph.D. in Animal Science-Environmental Toxicology (dual degree) from Michigan State University in 1998 and a M.S. in Environmental Health Sciences, specializing in solid and hazardous waste management, from East Tennessee State University in 1994. Her primary research focus has been quantitatively assessing children’s and adults’ exposures to pesticides and to other chemicals (e.g., bisphenol A) in their everyday environments such as homes and/or child care centers.
