Patricia ChampionView profile
Professor
Patricia Champion is a Professor in the Department of Biological Sciences at the University of Notre Dame, where she holds the title of Notre Dame Collegiate Professor. Her research is centered on the molecular mechanisms of mycobacterial pathogenesis, with a focus on protein transport and virulence. She is affiliated with the Eck Institute for Global Health and the Center for Rare and Neglected Diseases. PhD in Molecular Biology, Princeton University (2003) B.S. in Biological Sciences, Carnegie Mellon University (1998) Her research interests lie in understanding how pathogenic mycobacteria, including Mycobacterium tuberculosis and M. marinum , cause disease through targeted protein secretion, particularly via the Type VII (ESX-1) secretion system. She investigates how secreted proteins function as effectors and regulate gene expression, and how post-translational modifications like acetylation influence virulence. Her lab employs an interdisciplinary approach combining genetics, molecular biology, proteomics, and transcriptomics. The recent publications highlight a strong focus on ESX-1-mediated secretion, identification of novel substrates, regulatory mechanisms (e.g., WhiB6, EspM), and post-translational modifications. The work spans fundamental bacterial physiology to host-pathogen interactions, contributing to the broader goal of identifying targets for anti-virulence therapeutics against tuberculosis. Her scientific recognition includes being named a Notre Dame Collegiate Professor, a distinguished honor reflecting her scholarly excellence. Dr. Champion leads an active research laboratory committed to fostering an inclusive and respectful environment, emphasizing core values such as integrity, teamwork, and excellence. Her lab's work is supported by ongoing research grants, though specific funding sources are not detailed in the text. The Champion Lab operates within the Department of Biological Sciences and collaborates with key institutes at Notre Dame focused on global and neglected diseases.
