We study the atmospheric boundary layer using observational data to determine how contact with the ground influences atmospheric processes. This includes wind shear, turbulence, vertical mixing, and rapid heating or cooling. Using real-time and archived data we can understand the impacts of weather events on our local community and look at long-term trends of these impacts.

The ecology and epidemiology of enteric pathogens in wildlife, people, and livestock; Gates Foundation, Jim and Robin Herrnstein Foundation, Morris Animal Foundation, CDC

Effects of anthropogenic disturbance on patterns of parasitism in wildlife; US Fish & Wildlife, Maggioncalda Foundation, National Geographic, Wildlife Conservation Society

Wildlife vector-pathogen dynamics; NSF, NIH, European Union, CDC 

Goal of the Gillespie Lab

To determine how and why anthropogenic changes to tropical forests place people and wildlife in such ecosystems at increased risk of pathogen exchange. The central hypothesis of this work is that key human behaviors, wildlife behaviors, ecological conditions, and landscape features increase the risks of interspecific disease transmission. This effort entails a combination of epidemiology, molecular ecology, behavioral ecology, social and clinical survey, and spatially explicit modeling. The ultimate products are implementable plans for protecting human and wildlife health, while simultaneously ensuring the sustainability of the ecosystems within which they live.

Sponsored Research

An Integrated Assessment of Emissions, Air Quality, Economic, and Health Impacts of Transport Policies in China, sponsored by the Energy Foundation

Evaluating the relative importance of direct and indirect agricultural N2O emissions over the United States using forward modeling and atmospheric N2O and river nutrient data, sponsored by the National Oceanic and Atmospheric Administration

Additional Research

We conduct research related to the source, magnitude, and the impacts of emissions linked to air pollution, ozone depletion and climate change, as well as policy measures to reduce these emissions. Our current projects are:

Estimating past, present, and future global soil nitrous oxide emissions

Comparing various emissions inventories in Asia

Assessing what drives the seasonal and inter-annual variability of nitrous oxide emissions/mixing ratio

Quantifying the impacts of different emission sources on Asian air quality and health

analyzing indoor air quality in Tibet.

The eco-evolutionary dynamics of insecticide resistance in Aedes aegypti mosquitoes. Ministry of Education of Mexico and Emory Global Health Institute.

Macro-ecology of Infectious Diseases. NSF and NIH

Goal of theVazquez-Prokopec Lab

Our research focuses on four major vector-borne diseases of global health importance (Chagas disease, West Nile virus, dengue virus and malaria) and aims to answer the following questions:

How spatial heterogeneity and land-use patterns in urban and rural ecosystems determine patterns of vector distribution and pathogen transmission?

What is the contribution of host and vector movement to the dynamics of pathogen transmission?  

By identifying how vector borne diseases are distributed and maintained, how can we develop improved vector control and surveillance strategies?
