PhD Assistantships – US-Africa tick-pathogen modeling position(s) in the 
Quantitative Disease Ecology and Conservation (QDEC) Lab at UF for AY2019. 

​As part of an NIH R01 funded Ecology and Evolution of Infectious Diseases 
(EEID) grant “Spatial Eco-Epidemiology of Tick-Borne Rickettsial Pathogens”, we 
are seeking to fill 1-2 PhD track graduate positions in Medical Geography to 
conduct habitat selection modeling, niche modeling, and use other geospatial 
statistical techniques to explore questions of patterns and spread of ticks and 
pathogens of human concern in a paired system of southern Africa and the 
eastern USA. Successful applicants will join the QDEC Lab (www.sadieryan.net), 
which is jointly housed in the Department of Geography and The Emerging 
Pathogens Institute (EPI), at the University of Florida in Gainesville, FL. 
This project combines data sources at multiple scales, from coupling global 
scale remote sensing data with global vector records databases over multiple 
decades, to the fine-scale, examining intra-annual climatologies and ongoing 
records of field collected tick-pathogen samples, and understanding the 
interscalar implications of these in space and time.
 
This position offers the opportunity to work with multiple institutions on both 
continents, and truly be part of an international collaborative team in 
research, training, and capacity building. While the general research goals are 
defined, the candidate is expected to develop their own research questions and 
projects within the larger scope. Both domestic and international travel are 
anticipated as part of the project.

This position is primarily funded as a 12-month research assistantship (RA) for 
three years, with a year of TA-ship (i.e. stipend, tuition waiver, health 
benefits), annually reviewed for renewal with appropriate progress, with the 
opportunity to secure additional funding, as needed. Given the size and scope 
of the project, additional positions are expected through UF graduate school 
funding mechanisms.
 
Required:
Interest and enthusiasm for studying systems of tick-borne pathogen 
transmission as part of a collaborative research team
A masters in geography, ecology, biology, biostatistics, epidemiology, 
mathematics, or a related field, with emphasis on quantitative training (e.g. 
modeling, ecoinformatics, and/or statistics).

Desired:
Publication and/or presentation experience;
Prior experience working in a collaborative research team, knowledge of 
professional etiquette in group situations;
International experience, preferably with fieldwork;
Knowledge of R programming environment, or similar
Experience with data management, e.g. for ecoinformatics work, or GIS projects
Familiarity with niche modeling/habitat selection models/geospatial stats
 
QDEC Lab is home to multiple projects looking at the impacts and interactions 
of people, animals, and pathogens on the landscape in a changing world. We aim 
to produce both cutting-edge research, and to provide that research in useful 
formats to decision-makers, from local units (e.g. ministries of health and 
vector control units in Latin America, the Caribbean, Florida) to agencies 
making global decisions (e.g. USAID, WorldBank). We thus bridge multiple 
disciplines, and PI Sadie J. Ryan is part of many programs and centers on 
campus, including board member for the Center for African Studies, fellow of 
the Florida Climate Institute, and affiliate graduate faculty in Environmental 
and Global Health, Society for Natural Resources and Environment (SNRE) 
program, and Latin American Studies (LATAM).
