Research Assistant Professor, Department of Microbiology & Immunology
My research is focused on the metabolic plasticity of Mycobacterium, a fascinating genus that spans the most successful human pathogen Mycobacterium tuberculosis as well as important soil organisms like Mycobacterium smegmatis. By means of genetic engineering, metabolomics (UPLC-MS), transcriptomics, chemostat cultivation (using fully automated mini-bioreactors) and animal experiments I am studying the bioenergetics and metabolic pathways that allow these aerobic bacteria to adapt to adverse conditions in the host and the environment. My research has elucidated molecular mechanisms that are important for global hydrogen cycling as well as keeping the mycobacterial cell energized and metabolically active during host infection.
