![]() Catherine Lippi, PhD
Postdoctoral Associate, VectorByte Research Interests: ecological and anthropogenic factors affecting transmission of vector-borne diseases. By combining geographical, ecological, and epidemiological methodologies, I explore pathogen-vector-host interactions for tick and mosquito-borne diseases. Funding: NSF VectorByte Project Personal Website Google Scholar @aedeslady ![]() Gavriella (Gavi) Hecht, MPH Epidemiology
PhD track, Medical Geography, UF Research Interests: My interests revolve around disease ecology and spatial epidemiology, particularly as it relates to vector-borne and zoonotic disease. Using epidemiological and geographical methods, I am focused on understanding health at the human-animal-environment interface. Funding: UF Geography Teaching Assistantship ![]() Affiliate Researcher
Johnny A. Uelmen, PhD Research Interests: Infectious diseases, particularly zoonoses, are fascinating to me. Driven by the forces of environmental and climatic changes, zoonoses thrive - emerging and reemerging rapidly across the globe. To understand how these diseases survive from pathogen to host(s), I pursue these research questions with a One Health focus, integrating techniques and methods across multiple scientific disciplines. My work aims to model zoonotic disease transmission, estimate risk across time and space, and target elements that will mitigate the health burdens to humans, animals (including wildlife), and our environment. I am an Epidemiologist at the core, but my background includes Ecology, Entomology, Geography (and GIS), Environmental Studies, and Biology. My work is highly collaborative and interdisciplinary, often working with individuals in Public Health, Geography, Informatics, Veterinary, and Human Medicine. Google Scholar |
![]() Shreejana (Shree) Bhattarai, MSc Geog
PhD track, Medical Geography, UF Research Interests: landscape epidemiology and spatial analysis of infectious diseases, especially vector borne diseases like malaria and control interventions for successfully eliminating those diseases. Funding: UF Graduate School Fellowship CV Google Scholar @medgeoshree ![]() Affiliate Researcher
Marta Shocket, PhD Research interests: My work combines field data, lab experiments, and mathematical modeling to answer questions about how environmental factors (especially temperature and climate change) impact infectious diseases. I draw on perspectives from disease ecology, thermal biology, and trait-based ecology. I work on vector-borne diseases, including West Nile virus, and Ross River virus, as well as Daphnia zooplankton and their fungal pathogen Metschnikowia bicuspidata Google Scholar Website |
