As a member of the Center for Vector-Borne Infectious Diseases (CVID) at Colorado State University, the Foy laboratory focuses on the interactions of vectors with their hosts and with vector pathogens. The goal is to link research employing molecular, proteomic and genomic techniques to practical applications for controlling arthropod-borne diseases. A main research component in the Foy lab is to interrupt the intense transmission of malaria and arboviruses by targeting the vector through their bloodmeals using drugs that attack vector physiology and that inhibit pathogen development or using anti-vector immunity driven by vaccination. The Foy lab is also developing mosquitoes and other vectors as biosurveillance tools, studying unique aspects of arbovirus transmission and arbovirus survival in vectors, and studying poorly understood mosquito pathogens for their prospects to become vector-borne disease control tools.
Repeat Ivermectin Mass Drug Administrations for Malaria control II (RIMDAMAL II)
This is a cluster randomized clinical trial in Burkina Faso to test whether repeated ivermectin mass drug administrations, integrated into a monthly delivery platform with standard malaria control measures of seasonal malaria chemoprevention and insecticide-treated bed net distribution, will reduce childhood malaria incidence and limit resistance development in mosquitoes and parasites.
TRANSMIT: Tracking Antimalarial Resistance in Mosquito Populations
This project is designed to compare malaria parasite drug resistance tracking techniques using human blood samples versus using captured blood fed mosquito samples.
Comparison of mosquito age-grading measures in the RIMDAMAL II randomized, double-blind clinical trial
This project is comparing new and old mosquito age grading techniques within the context of our RIMDAMAL II clinical trial to best determine how different vector-control measures mosquito population age structure.
Aedes-borne arbovirus transmission
We are studying humans and animal models to characterize the viral dynamics, host responses and disease outcomes resulting from Aedes-borne arbovirus transmission. We are especially interested in understanding these outcomes from Zika virus transmission by the sexual and mosquito-borne routes. Our human studies partners are researchers at FIOCRUZ, Aggeu Magalhaes Institute, Recife, PE, Brazil.
Endectocides for West Nile virus control
This project designed to develop and test endectocide-treated bird feed for efficacy in controlling West Nile virus transmission. Our partners are colleagues at UC-Davis, CDC-DVBD, and TDA Research, Inc.

Brian Foyand his colleagues may have hit upon a way to dramatically reduce the spread of West Nile virus by using ivermectin to turn hungry birds into passive assassins.
Researchers at the University of California, Davis and Colorado State University have found evidence that adding ivermectin to backyard bird feeders has potential to reduce local transmission of West Nile virus in the U.S.
Brian Foy has been studying ivermectin for nearly a decade, long before it became a hot topic in the United States.
