Research Abstract:

Our research group develops novel technologies to understand, harness, and engineer the biochemical processing potential of microbial communities. We work at the interface of microbial genomics, quantitative ecology, synthetic biology, systems biology, and computational biology to study problems with biotechnological and biomedical relevance. Our current projects are focused on three major themes: (1) understanding the evolution and exchange of antibiotic resistance amongst diverse microbial communities, (2) engineering improved probiotics to treat gastrointestinal disorders, and (3) engineering microbial catalysts to produce value chemicals such as biofuels.

High-Throughput Functional Metagenomic Selections: Schematic representation of a culture-independent pipeline for identifying and quantifying selectable functions (e.g. antibiotic resistance) from any microbial genome or metagenome. Through a combination of recent experimental and computational innovations, the Dantas lab has decreased the cost of these methods by over 100-fold, enabling dramatic improvements in throughput for characterizing and modeling microbial community functions, dynamics, and ecology.
