Rachel Bleich

Rachel Bleich is an Assistant Professor in the Department of Biology at Appalachian State University, where she has conducted research on gut microbiome dynamics in inflammatory bowel disease (IBD) since 2020. Her work focuses on Crohn's-associated $$E. coli$$ strains and their impact on host-microbe interactions using molecular barcoding technology.

Education:

• Ph.D. in Pharmaceutical Sciences, University of North Carolina at Chapel Hill (2017)
• B.S. in Chemistry, Western Carolina University (2012)

Dr. Bleich's research investigates how strain-specific bacterial features and specialized metabolites shape microbial community structure and influence host health in IBD. Her laboratory employs molecular barcoding to overcome limitations of traditional 16S rRNA sequencing, enabling precise identification of functionally distinct $$E. coli$$ strains within complex microbiota. Key questions explore bacterial communication mechanisms, metabolite-mediated interactions, and their downstream effects on inflammatory pathways.

Her publication record shows a clear trajectory from bacterial physiology studies (2015-2017) toward microbiome-disease connections, with recent high-impact contributions examining microbiome roles in cancer development and IBD pathogenesis. The 2021 $$Annual Review of Medicine$$ article synthesizes evidence for microbiota involvement across all carcinogenesis stages, while her $$Science$$ perspective highlights emerging microbial carcinogen research.

Dr. Bleich actively mentors undergraduate and graduate students in laboratory research, providing hands-on training in microbiological and molecular techniques. Her work receives institutional support through Appalachian State University resources, though specific grant details aren't provided in source materials.

She maintains an active research laboratory in Rankin Science West, where her team investigates host-microbe dynamics with potential therapeutic applications for IBD treatment.
