Location: University of Washington Chemistry Building, room CHB 102 (NE corner, fountain level entrance)

Abstract: Our work centers around spirochetes, an ancient and unique phylum of bacteria that are challenging to study due to their fastidious nature and the scarcity of suitable research tools. Specifically, we focus on Treponema pallidum subsp. pallidum and pathogenic Leptospira species. These organisms are the causative agents of syphilis and leptospirosis, respectively, infection diseases with a profound impact on human and animal health. We use state-of-the-art mass spectrometry approaches, including imaging mass spectrometry, proteomics, and lipidomics, to study components of spirochetal membranes and the host-pathogen interface directly within infected tissues. The overarching goal is to identify molecular targets for improved diagnostics, surveillance, and prevention of spirochetal infections. Come and learn how various Mass Spectrometry techniques help in this research.
