Foy Lab

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.

The Foy lab is hiring for a Research Associate II position

The applicant will be involved primarily in research with mosquitoes and mosquito-borne infectious pathogens. The position also requires experience in rearing arthropod vectors (mosquitoes and other vectors) in our insectaries, and the ability to conduct molecular/cellular assays and perform experiments with arthropod vectors and the pathogens they transmit (arboviruses like West Nile virus, Plasmodium, etc.). It is preferred that the applicant have work experience collecting, handling and identification of mosquitoes in the field, experience in BSL-2 and/or BSL-3 laboratories, working with infectious pathogens, and/or animal handling.

Applicants must hold a minimum of a bachelor’s degree in a health sciences-related field and have 2 or more years of laboratory experience in microbiology (or related field), with practical experience with arboviruses and/or mosquitoes. The successful candidate will possess a strong work ethic and organizational and communication skills, knowledge of standard computer applications used in laboratory and field research, and the ability to work productively and collegially as a member of a large and diverse research team.

Please contact Brian Foy via email and apply to the MIP Research Associates I, II, or III Open Pool.

research project

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.

research project

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.

research project

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.

research project

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.
