Nicole Gonzalez, M.S., joined the Occupational and Environmental Epidemiology Branch (OEEB) as a postbaccalaureate fellow through NCI's Introduction to Cancer Research Careers (ICRC) program in July 2020. She earned her Master of Science degree in epidemiology from The George Washington University's Milken Institute of Public Health, where her thesis research was focused on healthcare utilization trends among cancer survivors. 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.

Catherine Lerro, Ph.D., M.P.H. - Research Fellow

Catherine Lerro, Ph.D., joined the Occupational and Environmental Epidemiology Branch (OEEB) in August, 2013 as a predoctoral fellow within the Yale-NCI Cooperative Graduate Training Program in cancer epidemiology. She became a postdoctoral fellow in December 2015, after successfully defending her dissertation, and was promoted to research fellow in December 2018. Dr. Lerro received her B.A. in public health studies from Johns Hopkins University in Baltimore, Maryland, her M.P.H. in chronic disease epidemiology from Yale University in New Haven, Connecticut, and her Ph.D. in environmental epidemiology from Yale. She was previously a summer fellow at NCI and wrote her master’s thesis under the mentorship of Michael B. Cook, Ph.D., and Katherine A. McGlynn, Ph.D., M.P.H. Dr. Lerro also spent two years working as an epidemiologist at the American Cancer Society in Atlanta, Georgia. She is currently working with Laura Beane Freeman, Ph.D., senior investigator, OEEB, examining agricultural exposures and cancer risk in men and women.

Jessica Madrigal, Ph.D., M.S. – Postdoctoral Fellow

Portrait of Jessica Madrigal

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.
