Host-pathogen interactions, Lipids/Sphingolipids function in viral and bacterial infections

Advertised on 

Oregon Health & Science University (OHSU), Portland, OR, USA


A postdoctoral fellow position is available in the laboratory of Fikadu G. Tafesse in the Department of Molecular Microbiology & Immunology at Oregon Health & Science University in Portland, OR, USA.

Our laboratory studies to understand how pathogens use host factors to secure invasion, persistence, and propagation. We are especially interested in studying the roles of cellular (sphingo)lipids in bacterial and viral pathogenesis and their significance on innate and adaptive immunity. The microbes we study include the bacterium M. tuberculosis and the emerging and re-emerging viruses, including SARS-CoV-2, Zika virus, and HIV. We employ new chemical probes such as multi-functional lipid analogs to investigate the mechanisms and pathways that control infections.

The Tafesse lab is well funded and offers a scientifically inspiring environment with access to the state-of-the-art facilities in proteomics, metabolomics, lipidomics, and advanced microscopy. The candidate will have ample opportunities to acquire and develop new skills, including working with Bio-Safety Level-3 pathogens and collaborating with various national and international scientific teams.
