Outside of academia, River enjoys hiking, reading, thrifting, trivia nights, and exploring the outdoors with her dog Boba.
Current Postdoctoral Trainees
Brennan Baker, DEOHS
Brennan completed his PhD in Environmental Health Sciences at Columbia University in 2022. He is an environmental molecular epidemiologist investigating the links between prenatal exposures and children’s health and their underlying molecular mechanisms. His PhD work was the first to examine human functional brain phenotypes in relation to prenatal acetaminophen, showing that acetaminophen exposure measured in meconium was associated with child Attention Deficit Hyperactivity Disorder (ADHD), and that the association was mediated by functional brain connectivity measured via functional Magnetic Resonance Imaging (fMRI). Follow-up work uncovered that prenatal acetaminophen may increase risks for low birthweight and reduced gestational age, but that these adverse birth outcomes do not mediate links with child ADHD. Serving as a co-investigator on a pilot grant, Brennan conducted the first study of the effects of prenatal acetaminophen exposure on genome-wide gene expression (via RNA-sequencing) in the brain (using a mouse model). As a BEBTEH postdoctoral fellow, Brennan is working under the mentorship of Dr. Sheela Sathyanarayana. Gene expression studies are uncommon in observational epidemiology, and Brennan’s postdoctoral work is at the leading edge of methods development integrating epidemiologic and transcriptomic approaches. He developed the only existing RNA- sequencing analysis pipeline allowing for multiple imputation of missing covariate data and conducted the largest analysis of the relationship between prenatal psychological stress and the placental transcriptome to date. Spanning beyond prenatal pharmaceuticals, Brennan’s work has also examined the impact of prenatal exposures to ubiquitous environmental chemicals including phthalates, parabens, and flame retardants.
Carrie Fahey, Epidemiology
Carrie Fahey is a postdoctoral scholar in the Department of Epidemiology. Her research seeks to elucidate and address intersecting social and environmental determinants of health. She completed her MPH and PhD in Epidemiology at the University of California, Berkeley, where she used impact evaluation and implementation science to understand the effects of behavioral economic interventions on health care access, utilization, and outcomes. Carrie’s current work examines how climate and environmental exposures affect vulnerable populations, including marginalized communities, people living with HIV and other chronic conditions, older individuals, pregnant people, and children. She uses quasi-experimental and spatiotemporal methods to analyze large datasets, from collaborative consortiums to electronic medical records. She also has extensive experience designing mobile health technology (mHealth) systems and conducting primary data collection, including randomized controlled trials and longitudinal cohort studies in both the United States and global settings.
John Flunker, DEOHS
Dr. Flunker completed his PhD in environmental and occupational epidemiology at the University of Kentucky in 2021. He specializes in occupational and residential exposure assessment, exposure-outcome modeling, and promoting the health of vulnerable populations. Working in a multi-disciplinary and stakeholder-engaged context, Dr. Flunker has examined factors related to adverse health outcomes and implemented evidence-based workplace interventions among Latino thoroughbred horse farm workers, elucidated the relationship between resource extraction particulate exposures and respiratory health experienced by residents of rural Appalachia Kentucky, and co-led a Maryland casino worker occupational safety research feasibility study designed to explore under-reported industry hazards. His past research support includes two studies funded by the National Institute of Environmental Health Sciences (NIEHS) and the Centers for Disease Control and Prevention - National Institute for Occupational Safety and Health (CDC-NIOSH) where Dr. Flunker served the role of co-investigator. He was also the principal investigator of two pilot studies funded by the University of Kentucky CDC-NIOSH Educational Research Center and the Southeast Center for Agricultural Health and Injury Prevention. As a BEBTEH post-doctoral fellow Dr. Flunker continues his research in occupational and environmental epidemiology, focusing primarily on agricultural worker heat and particulate exposures, yet broadens his research diversity, expertise, and impact via academic and industry stakeholder collaborations, policy-informing research, and small-scale region-specific occupational epidemiology studies. Dr. Flunker serves as a mentor for the Supporting Undergraduate Research Experiences in Environmental Health (SURE-EH) program and collaborates with the Pacific Northwest Agricultural Safety and Health Center.
Emilia Vignola, Epidemiology
Emilia (Emma) Vignola completed her PhD in Community Health and Health Policy at the City University of New York School of Public Health in 2023. Her multi-methods dissertation drawing on both primary and secondary data focused on understanding and mitigating the health influences of precarious employment among food chain workers. She is interested broadly in how work and employment quality influence health and health equity, as a way of incorporating questions of power into her public health research and practice. While pursuing her doctorate she worked as a fellow at the CUNY Urban Food Policy Institute on research and advocacy related to food labor and food justice. She also collaborated on a multi-country qualitative study on non-standard employment and health as part of the Precarious Work Research consortium. As a BEBTEH postdoctoral trainee, she will work with Dr. Anjum Hajat on research projects related to measuring precarious employment and its health impacts, and with Dr. Marissa Baker on an evaluation of a mentorship program for women in construction.
