She led the exposure assessment research team in the Field Research Branch which conducted biological monitoring research for occupations exposed to flame retardants, PFAS, bisphenol A, bromopropane, pesticides, phthalates, etc. She chaired the NIOSH Institutional Review Board for several years and coordinated the Services Sector for the National Occupational Research Agenda. Her research projects include measuring exposure to chemicals, biological hazards, noise, and musculoskeletal disorders within many industries including construction, agriculture, beauty salons, appliances, furniture stripping, electronic waste and others.
MemberZhihua (Tina)Fan
Zhihua (Tina) Fan, PhD, is the Director of Environmental and Chemical Laboratory Services at the NJ Department of Health (NJDOH). Prior to joining the NJDOH in 2014, she was an associate professor in the Exposure Science Division of Rutgers University's Department of Environmental and Occupational Medicine. She has extensive experience in exposure science, environmental health, environmental sampling and analysis. She has published more than 40 scientific research articles, five book chapters/invited articles, more than 50 presentations at a variety of scientific conferences. Dr. Fan currently serves on the US EPA Science Advisory Board and the Editorial Review Board of the Journal of Exposure Science and Environmental Epidemiology.
Danelle Lobdell, PhD, is an epidemiologist with the EPA in the Office of Research and Development. She received her MS in Natural Sciences and her PhD in Epidemiology and Community Medicine from the University at Buffalo, The State University of New York. Dr. Lobdell’s current research involves the development of environmental public health indicators that can be tracked over time. She recently publically released the Environmental Quality Index 2000-2005 for all counties in the US. She also has several research projects funded through the Regional Applied Research Effort that focus on the EPA’s regional research needs for communities. Dr. Lobdell has a strong research interest in the area of reproductive, perinatal, and children’s health outcomes.
Dr. Marc A. Nascarella is a health scientist with broad training in public health, toxicology, epidemiology, and exposure science.  He currently serves as a full-time graduate faculty member at the Massachusetts College of Pharmacy and Health Sciences.  His professional interests are focused on applied prevention science and how to rapidly translate the best available science into practical tools that inform policy, public health practice, and healthcare delivery. He serves as an advisor to government and non-governmental agencies on approaches to reduce the contribution of environmental contamination to human disease.  He has led initiatives focused on building capacity in underserved domestic and international communities, and served as a lead investigator on multiple large-scale biomonitoring studies in the US and abroad. Efforts have largely focused on identifying individuals in residential and occupational settings with a disproportionate burden of exposure to metals.  Other efforts include establishing regionally appropriate baseline (population-level) estimates of exposure to PCBs as well as metals and metalloids.  In addition to biomonitoring of environmental contaminants, he has conducted biomonitoring studies to characterize baseline levels of marijuana and marijuana metabolites in individuals who regularly consume regulated retail marijuana products.  Dr. Nascarella is a certified public health professional (CPH) and has previously served as the State Toxicologist for the Department of Public Health in the Commonwealth of Massachusetts.
