Research Overview

Led by Dr. Nicole Buan, this project's goal is to identify molecular metabolic signals of microbial syntrophy in the human gut, with the long-term goal of developing a predictive model relating host diet to healthy gut microbiota resiliency. In collaboration with Massimiliano Pierobon (Computer Science and Engineering), Myra Cohen (Computer Science and Engineering), and Christine Kelley (Mathematics), wet-lab physiological and biochemical data will be used to evaluate and refine theory-driven computational models of microbial community metabolism.
