While pursuing joint degrees in mathematics and biostatistics at the University of North Carolina at Chapel Hill as an undergraduate, she also worked at the National Institute of Environmental Health Sciences on epidemiologic studies of ovarian cancer risk. In DCEG, Ms. Gonzalez is working with Stella Koutros, Ph.D, M.P.H., investigator, OEEB, evaluating the relationship between occupational and environmental exposures and bladder tumor characteristics and etiologic heterogeneity in bladder cancer.
Jessica Madrigal, Ph.D., M.S. – Postdoctoral Fellow
Jessica Madrigal, Ph.D., M.S., joined the Occupational and Environmental Epidemiology Branch (OEEB) as a postdoctoral fellow in March 2020. Dr. Madrigal received her Ph.D. in environmental and occupational epidemiology from the University of Illinois at Chicago, where she was a National Institute for Occupational Safety and Health (NIOSH) predoctoral fellow. Her dissertation research focused on the relationships between persistent organic pollutant exposures, endogenous pituitary, sex steroid, and thyroid hormones, and renal endpoints among Hispanic and Latino adults. During her academic training, Dr. Madrigal’s work focused on chronic disease prevention and health disparities, and she has collaborated on studies to evaluate the associations between heavy metal exposures and pulmonary function among children, in addition to descriptive studies aimed to reduce health disparities among women. In OEEB, Dr. Madrigal works with Rena Jones, Ph.D., M.S., investigator, and Mary Ward, Ph.D., senior investigator, on studies using geographic information systems (GIS) for environmental exposure assessment and to identify determinants of environmental exposures that are related to cancers, and cancer risk, in adults and children.
Cherrel K. Manley, M.S.P.H. – Postbaccalaureate Fellow
Cherrel Manley, M.S.P.H., joined the Occupational and Environmental Epidemiology Branch (OEEB) as a postbaccalaureate fellow within the Intramural Continuing Umbrella of Research Experiences (iCURE) program in August 2020. Ms. Manley earned her M.S.P.H in epidemiology from the University of North Carolina at Chapel Hill in 2020. Working with Drs. Stephanie and Lawrence Engel, her master’s research focused on prenatal exposure to organophosphorus pesticides and preschool ADHD in the Norwegian Mother, Father, and Child Cohort. Ms. Manley’s research interests include environmental and occupational exposures, as well as disparities in exposures and cancer-related health outcomes. As an iCURE Scholar, she is working with Mary Ward, Ph.D., senior investigator, OEEB and Rena Jones, Ph.D., investigator, OEEB, to investigate residential and drinking water exposures and cancer risk in the Agricultural Health Study.
Jongeun Rhee, Sc.D., M.S. – Postdoctoral Fellow
Jongeun Rhee, Sc.D., M.S., joined the Occupational and Environmental Epidemiology Branch (OEEB) in September 2019 as a postdoctoral fellow. Dr. Rhee completed her Sc.D. in environmental health with a concentration of environmental, occupational, and molecular epidemiology from the Harvard T.H. Chan School of Public Health in Boston, MA. For her dissertation research, she investigated associations between air pollution, industry, and socioeconomic status and acute respiratory distress syndrome among older adults in the United States. Dr. Rhee received her M.S. in environmental health from the Harvard T.H. Chan School of Public Health, and her B.S. in environmental health and life sciences from Korea University in Seoul, South Korea. In OEEB, Dr. Rhee will be working with Mark Purdue, Ph.D., senior investigator, on projects investigating cancer risks associated with environmental exposures to radon, solvents, and other agents, as well as molecular epidemiologic studies of kidney cancer etiology.
Jason Wong, Sc.D. - Research Fellow
Jason Wong, Sc.D., S.M., joined the Occupational and Environmental Epidemiology Branch (OEEB) in October 2015 as a postdoctoral fellow and is currently a research fellow. Dr. Wong obtained his bachelor’s degree in cell and molecular biology from Simon Fraser University and his dual-doctorate in epidemiology and environmental health from the Harvard T.H. Chan School of Public Health. For his doctoral dissertation research, he examined the detrimental effects of fine particulate matter on telomere length, DNA methylation, and inflammation. Prior to joining OEEB, Dr. Wong completed a postdoctoral fellowship at Stanford University School of Medicine where he examined the chronic health effects of secondhand smoke. Dr. Wong also has extensive experience in molecular biology honed from nearly a decade as a laboratory manager at the Brigham and Women’s Hospital – Harvard Medical School. Dr. Wong previously characterized genetic variants related to risk of endometrial cancer in the Nurses’ Health Study, and he is best known for developing a high-throughput assay to measure telomere length. In DCEG, Dr. Wong is investigating environmental, occupational, and molecular factors related to risk of cancers in various Asian and Western cohorts. He is working under the mentorship of Qing Lan, M.D., Ph.D., and Nathaniel Rothman, M.D., M.P.H., M.H.S., senior investigators in OEEB, to uncover the etiologic underpinnings of lung cancer.
