Elizabeth Carlton is an associate professor in the Department of Environmental & Occupational Health at the Colorado School of Public Health. She is an environmental epidemiologist who studies the ways in which social and environmental conditions—from climate change to urbanization—impact infectious diseases. She is interested in improving surveillance tools for infectious diseases and identifying vulnerable populations and high-risk environments. Her research over the past decade has helped to clarify the impacts of climate change on water-borne diseases.

Dr. Carlton leads a research program using next generation genomics and field epidemiology to understand barriers to schistosomiasis elimination in residual transmission hotspots. She is currently working with investigators from the University of Colorado’s Anschutz Medical Campus, CU Denver and CU Boulder to develop mathematical models to estimate the trajectory of COVID-19 in Colorado and the potential impacts of transmission control strategies. 

Professor Carlton teaches courses on environmental epidemiology, the health impacts of climate change, and global health. She received her PhD in Environmental Health Sciences from the University of California Berkeley, her MPH from the Mailman School of Public Health at Columbia University, and her BS in biology from Yale University. Prior to graduate school, she was a Peace Corps Volunteer in Honduras.

Elise Grover, MSPH, DrPH Candidate

Elise began her DrPH in Environmental & Occupational Health in 2017 with an interest in studying the impacts of climate change on infectious diseases and human health. She received her MSPH in International Health in 2015 from Johns Hopkins Bloomberg School of Public Health. She is currently assisting with research on the roles of climate and behavior in COVID-19 transmission, and research examining potential environmental predictors of Schistosoma japonicum infection in rural areas of Sichuan, China.

Dave Johnson, MS Student

Dave is pursuing a Master of Science in Epidemiology. He attended Harvard as an undergrad, and previously explored finance, app development, and copywriting before attending the Colorado School of Public Health. He is currently assisting with modeling projects around the COVID-19 outbreak in Colorado.

Irina Kararskis headshot

Irina Kasarskis, MPH, DrPH Student

Irina is a DrPH student in the Department of Epidemiology. She received her MPH in Biostatistics and Epidemiology from Boston University School of Public Health. She previously worked as an epidemiologist for the State of Oregon and has an interest in infectious diseases. In the Carlton Lab, she works on regional models with the COVID-19 modeling team.

Andrea Lund headshot

Andrea Lund, MPH, PhD

Dr. Lund is a health and environmental scientist interested in how social factors interact with environmental drivers of infectious disease transmission. As a postdoctoral fellow, she is integrating genomic and epidemiologic data to understand schistosome transmission in Sichuan, China. She received her PhD from the Emmett Interdisciplinary Program in Environment and Resources at Stanford University, where her dissertation research focused on human ecology of schistosomiasis in Senegal, West Africa. Previously, she studied the ecology of mosquito-borne disease in urban Atlanta and the role of social factors in explaining environmental risk for cholera in the Dominican Republic. In addition to the PhD, she holds an MPH in global epidemiology from the Rollins School of Public Health at Emory University and a bachelor of arts in biology and Spanish from the University of Minnesota, Morris.

Olivia Zarella headshot

Olivia Zarella, MPH, DrPH Student

Olivia is an Environmental & Occupational Health DrPH student in Dr. Carlton’s research group. She received her MPH in Global Environmental Health at Emory University where she became interested in the control of arboviruses and the influence of climate change on vector distribution. To support future Aedes-borne disease risk-mapping, Olivia is assisting with projects focused on the surveillance of Aedes mosquitoes in Ghana. She is currently employed as an Infection Disease Specialist for the Environmental Health and Safety Office on the CU Anschutz campus. In this role, Olivia manages the campus COVID-19 contact tracing program, oversees BSL-3 laboratory safety protocols, and provides recommendations to campus leadership related to infectious disease preparedness and response policies.
