2020-2021 TRAINING GRANT RECIPIENTS
“Improving public health surveillance of Onchocerca lupi through increased host and vector screening”
Chandler Roe, M.S., Trainee
Chandler Roe is a Ph.D. student in informatics and computing with an emphasis on bioinformatics at Northern Arizona University. Roe’s work in Dr. Jason Sahl’s lab has focused on population genomics of infectious diseases, with particular interest regarding the genomics of the vector-borne disease, Onchocerca lupi in Northern Arizona. She hopes her research conducting targeted and controlled sampling of hosts and vectors of O. lupi will directly inform vector control units to employ black fly control efforts near high-risk areas thus breaking the transmission cycle. Once completing her Ph.D., Roe plans to establish her career as a researcher in parasite genomics in academia.
The Sahl Lab focuses on the genomics of infectious disease agents. They develop new bioinformatics approaches to answer questions on emerging antimicrobial resistance mechanisms, pathogenesis, and phylogeography. The Sahl Lab also apply these methods to biowarfare agents in order to provide optimized diagnostics for early detection and targeted interventions. Their work has application to the public health community as well as the biodefense community focused on protecting our deployed troops.
