John G Purdy

Assistant Professor

John Purdy earned an undergraduate degree from Pacific University and a Ph.D. from Penn State University College of Medicine. He performed his graduate studies in the biochemistry of assembly retroviral capsid in the laboratory of Drs. Rebecca Craven and John Flanagan. Afterwards he trained in metabolomics at the Lewis-Sigler Institute for Integrative Genomics, Princeton University while working in the laboratories of Drs. Joshua Rabinowitz and Thomas Shenk. He has been a member of the UA faculty since October 2015.

Research Interests: 

All viruses hijack host cell machinery to facilitate their replication. Producing infectious viral progeny relies on host cell metabolic pathways to provide energy and building blocks such as nucleotides, amino acids, and lipids. I am interested in investigating the molecular remodeling of cellular metabolic and lipid environments by viruses. The overall goal of my research in dissecting the complex virus-host metabolism interactions is to guide the development of novel antiviral therapies.
