Elise Grover headshot

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.

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.

Elizabeth Morris, MPH Student

Elizabeth is a second year Master of Public Health Student concentrating in Epidemiology. She is currently working on a project modeling Aedes distribution in West Africa utilizing citizen science and helping to create a curriculum to engage Ghanaian students in Aedes larvae surveillance. She is additionally examining distribution and human exposure to Dermacentor ticks in Colorado in a project outside of the Carlton Lab.

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.
