Kathryn Hughes Barry, Ph.D. - Postdoctoral Fellow

Kathryn Hughes Barry

Kathryn Hughes Barry, Ph.D., joined the Occupational and Environmental Epidemiology Branch (OEEB) in 2009 as a predoctoral fellow through the Yale/NCI Partnership Training program. Dr. Barry received a B.S. from Tufts University in 2003, and her M.P.H. from Yale University in 2005. Prior to beginning her doctoral program, she spent two years as a CDC/CSTE Applied Epidemiology Fellow at the Washington State Department of Health, where she engaged in cluster investigations of non-infectious conditions, including childhood and breast cancers and aplastic anemia. In her dissertation research in OEEB, Dr. Barry investigated cancer risk associated with pesticide exposures and the modifying role of inherited genetic variation in DNA repair genes in the Agricultural Health Study (AHS). After receiving her Ph.D. from Yale in 2011, Dr. Barry was promoted to postdoctoral fellow. She is working with Michael C. R. Alavanja, Dr.P.H, senior investigator, OEEB, to continue her research on pesticides and their interactions with genetic factors with respect to cancer risk in the AHS . In addition, Dr. Barry is working with Sonja Berndt, Pharm.D., Ph.D., investigator, OEEB, to study the relationship between epigenetic variation, genetic variation, and cancer risk, as well as epigenetic variation associated with occupational/environmental exposures, in various studies. She is a member of the American Association for Cancer Research and the Society for Epidemiologic Research.

Dr. Dai is a professor in the Institute of Occupational Health and Poison Control, China CDC. Her research is focused on the harmful effects of environmental and occupational chemicals, particularly on the immunological biomarkers and pathogenesis of hypersensitivity dermatitis induced by occupational exposure to trichloroethylene. Dr. Dai is conducting research in OEEB on the molecular epidemiology study of workers exposed to diesel exhaust and carbon black in China. Her primary mentors are Qing Lan, M.D., Ph.D., M.P.H., and Nathaniel Rothman, M.D., M.P.H., M.H.S., both senior investigators, OEEB.

Maki Inoue-Choi, Ph.D., M.S. - Postdoctoral Fellow

Maki Inoue-Choi, Ph.D., M.S., joined the Occupational and Environmental Epidemiology Branch (OEEB) as a postdoctoral fellow in October 2013.  She has a joint appointment with the National Institute on Minority Health and Health Disparities. Dr. Inoue-Choi received her M.S. in nutritional sciences from the University of Washington in 2006 and Ph.D. in epidemiology from the University of Minnesota in 2012.  After completing her doctoral degree, Dr. Inoue-Choi joined the Division of Epidemiology and Community Health of the University of Minnesota as a research associate. Working with her primary mentor, Mary Ward, Ph.D., senior investigator, OEEB, Dr. Inoue-Choi is evaluating the extent to which chronic exposures to environmental toxicants from drinking water are associated with the risk of cancers, especially in rural and agricultural areas. She is particularly interested in whether nutrients and environmental toxicant residues in food and water interact in the risk of cancer, and how diet can be used to mitigate the harmful effects of environmental toxicants.

Rena Jones, Ph.D. - Research Fellow

Rena Jones, Ph.D., joined the Occupational and Environmental Epidemiology Branch (OEEB) as a postdoctoral fellow in September 2012, and was promoted to a Research Fellow in early 2014. Dr. Jones’ research focuses on environmental exposures and the application and validation of spatial-analytical approaches for epidemiologic studies. She received a B.S. in biology from the University of Massachusetts and M.S. and Ph.D. degrees in epidemiology from the University at Albany, SUNY School of Public Health. Her doctoral dissertation investigated health risks associated with ambient outdoor particulate matter and the validity of spatial imputation methods for GIS-based exposure assessment.  She is currently involved in several OEEB projects and DCEG collaborations. Under the mentorship of OEEB senior investigator Dr.Mary Ward, and the direction of OEEB investigator Dr. Laura Beane Freeman, she is conducting research on multiple environmental exposures and cancer risk. Working with OEEB Chief Dr. Debra Silverman, Dr. Jones is also co-principal investigator of a study of outdoor particulate air pollution and lung cancer risk.
