Colleen Webb

I am broadly interested in the evolution of traits important in ecological interactions and in how evolution shapes communities and ecosystems. I also seek to do work with applied meaning. For example, I am interested in how highly virulent pathogens persist as well as understanding the drivers of spatio-temporal spread in pathogen-host systems in order to inform management decisions. I have also worked on a number of conservation issues as well as how selective processes on traits determine community and ecosystem function responses to environmental change. I work in a number of different empirical systems and use a variety of analytical and simulation methods.

I am a disease ecologist interested in how we can use pathogen surveillance data and apply tools from graph theory in a novel way, to better understand broad scale spatial transmission of multi-host disease systems. My dissertation research focuses on quantifying spatial patterns of prevalence, and modeling the international movement of avian influenza viruses via migratory waterfowl.

I work in the field of veterinary wildlife disease ecology, researching factors that drive disease spread and severity, with interests in One Health systems that integrate human, animal, and environmental health. I am interested in scaling individual health processes to predict population levels of mortality. In my thesis work I focus on how host-environment interactions influence disease outcome by using metabolic models to predict bat mortality from white nose syndrome as a function of spatiotemporal microclimate measurements in hibernation.

I am an epidemiologist and quantitative infectious disease ecologist with experience working abroad (Egypt, Zambia, Tanzania, Ethiopia) and domestically (Military Health System) on interdisciplinary teams. I am interested in emerging, infectious pathogens of humans and animals and working in multi-host disease systems. My dissertation research focused on establishing epidemiological patterns, risk factors, and parameters as well as dynamical modeling of peste des petits ruminants virus dynamics among sheep, goats, and cattle in northern Tanzania. I continued to explore the role of cattle in PPRV transmission in my first postdoc through experimental transmission trials in Ethiopia. In Webb lab, I work on developing and/or using statistical and mathematical models of domestic livestock (cattle and swine) movement networks, wildlife movement networks (avian influenza), and am a Co-Primary Investigator on collaborative vector-borne disease research of cattle fever ticks at the livestock-wildlife interface with the USDA and the Cattle Fever Tick Eradication Program. Additionally, I continue involvement in the VectorBiTE research coordination network and the FAO/OIE PPRV Global Research and Expertise Network.

I am a disease ecologist, broadly interested in understanding and forecasting infectious disease dynamics across scales. I use a variety of data-driven theoretical methods to explore questions about how certain factors (e.g. abiotic and biotic conditions, population demography and movement patterns, and interventions), operating at different spatial and temporal scales influence the population-level dynamics of infectious diseases. Currently, my primary effort is focused on several international collaborative livestock disease projects to develop ensemble forecasting methodologies, explore outbreak variability, and the effect of movement patterns, infrastructure and demography on potential outbreaks and the effectiveness of response actions in the United States. In addition, I collaborate on several smaller projects involving human vector-borne disease and the livestock-wildlife disease interface.

I am an ecology researcher interested in the many ways invasive species will interact with the effects of climate change. My previous work has looked at how environmental factors affect the microbial communities associated with various invasive species. My goals include interpreting ecological data to tell a story, for stakeholders and for the human community.

Sam Smith

I am joining the Webb Lab as plant community ecologist and an aspiring disease ecologist. My previous work aimed broadly to understand factors influencing plant community composition in a variety of ecosystems, and whether leaf, stem, and root traits could explain those community dynamics. I hope to apply my interest in traits to disease systems to assess the risk of disease outbreak and spread.
