Associate Professor


Gonzalo’s research interests are multidisciplinary and lie at the interface of ecology, spatial epidemiology, and global health. He bases his research program on the notion that disease occurrences are the result of intricate and complex interactions between hosts, pathogens, and natural or human-altered environments. He centers on vector-borne diseases such as dengue virus, West Nile virus and Chagas disease. He is motivated by the public health challenges faced by our increasingly urbanized world.


Kristina Roy

    Postdoctoral Researcher


    Oscar studied Biology, Zoology, and Botany at the National University of Northeast Argentina where his work focused on paleontology and biology of invertebrates and associated zoonotic diseases. He specialized as a medical entomologist working with parasitology of Chagas disease. Before earning his M.S. in Environmental Sciences and his Ph.D. in Biomedical Sciences from the Hebrew University of Jerusalem with work focusing on the eco-epidemiology and transmission dynamics of visceral leishmaniasis in Ethiopia. At the Prokopec Lab, he is the general coordinator of the T-IRS project and aids in undergraduate lab research.

    James Earnest, PH.D.

    Postdoctoral Researcher


    James studied Biology at Wake Forest University before obtaining a M.S. degree at the University of Georgia where he studied diagnostic and vaccination strategies for influenza infection at the population level. James went on to get a Ph.D. at Loyola University in Chicago researching how coronaviruses infect human cells and move between species. Following his Ph.D., James started a postdoc at Washington University in St. Louis studying the immune response of mice and humans to alphavirus infection. In the Prokopec lab, James is interested in applying his knowledge of viral immunology to the study of viral ecology, mapping population susceptibility to emerging arboviruses, and developing mechanisms to predict disease transmission and severity.

    Graduate Student - Population Biology, Ecology, and Evolution

    Sebastián is a Fulbright scholar and Ph.D. student from Colombia. He earned both his B.Sc. in biology and his M.S. in agricultural sciences from the National University of Colombia. While at UNC, he was involved in research on the ecology of mosquitoes. His research interests center around biology, ecology, and the control of mosquito vectors that transmit diseases to humans. His current research delves into the release of lab-reared mosquitoes containing the endosymbiont Wolbachia as a biological control mechanism against mosquito species that are invasive to Latin America. He is motivated by the real-world applications of his ecological research to help fight disease.

    Tim Walsh

    Graduate Student - Environmental Health


    Tim Walsh is a second-year MPH student studying Environmental Health. He received his B.S in Biological Sciences from DePaul University in Chicago where he worked as a research assistant in a genetics and molecular biology lab on zebrafish promoter analysis. Tim joined the lab in the spring of 2021 and is currently working on his Master’s thesis, focusing on the variation in tick population abundance and disease transmission potential during the field season. He is broadly interested in how the principles behind vector ecology can be applied to prevent disease outbreaks as well as how different environmental factors may impact the suitable habitats of disease vectors.

    Carlos Culquichicon

    Graduate Student - Environmental Health and  Epidemiology

    Carlos is currently enrolled in the MSPH of Environmental Health and Epidemiology. His current research is about the age structure of mosquito populations intervened under a targeted insecticide residual spraying in communities from Merida-Mexico.  His methodological interests rely on g-methods for time-variant treatments and other causal inference methods applied in arboviral disease trials. 



    Undergraduate Student - Biology and Psychology

    Luiza is a junior studying biology and psychology. She joined the Prokopec Lab in the spring of 2019 as a volunteer helping with mosquito trapping and data collection. She currently helps in DNA extraction and PCR procedures studying epidemiology of tick-borne diseases. She intends to attend medical school after graduating from Emory.
