Bio

Rabi earned his Ph.D. in Microbiology/Cell and Molecular Biology from Oklahoma State University under the supervision of Dr. Matthew Cabeen. He continued as a postdoctoral researcher in the same lab, where he investigated the stress sensing mechanisms in Bacillus subtilis, focusing on the regulation of the alternative sigma factor SigB and the functions of its associated signaling components. To further deepen his expertise in microbial genetics and molecular biology, Rabi joined Dr. Ann Stock’s lab as a Postdoctoral Fellow. His current research focuses on understanding how Hybrid Two-Component System (HTCS) transcription factors regulate the utilization of dietary fibers and host glycans in the gut bacterium Bacteroides thetaiotaomicron (B. theta), providing insights into bacterial gene regulation within the gut microbiome.
