Biography:

Kristin Jacob is a Ph.D. candidate in the lab of Dr. Gemma Reguera whose research interests are focused in microbial pathogenesis, molecular microbiology, natural products and the microbiome. Her current research focuses on studying the microbiome of the middle ear. As part of a larger DoD funded project, she aims to identify the native community of the middle ear microbiome, with special interest in exploring the community differences between divers and non-divers and identify those with highest potential for development of bacterial replacement therapies targeting the prevention/treatment of barotrauma in divers. Presentation of her research at the 2019 SIMB Annual Meeting earned the Best Student Poster award in the Natural Products division of the conference. Kristin earned her B.S. in Biology, with a concentration in microbiology, and a M.Sc. in Biology at Northern Michigan University where her research focused on studying the role a novel two-component system played in virulence of Pseudomonads and compared its role in a homologous system in Vibrio cholerae. Prior to starting her doctoral program, she continued her research focus in bacterial pathogenesis as a research technician at the University of Michigan, where she studied gene regulation in Group A Streptococcus. Outside of the lab, Kristin actively participates in outreach programs through various on campus organizations and promotes graduate student and post-doc engagement in social and professional development programs/workshops through her position in the Michigan chapter of Graduate Women in Science (GWIS).
