The gut microbiota, characterized as the microbiome, plays a pivotal role in human health, function, and disease. Our primary research focus is to characterize patterns in microbiome imbalance, called dysbioses, that affect the onset and progression of diseases. We use next-generation sequencing, metagenomics approaches, ecological principles, and translational mouse models to fully understand shifts in microbial community composition, organization, and function in the hopes of developing personalized, microbiota-based therapeutics and practices. Current areas of study include:

1. Determining the role of the microbiome in the onset and progression of obesity.

2. Assessing changes and mechanisms of the gut microbiota associated with surgery and surgical outcomes.

3. Characterizing shifts in gut microbiota related to intestinal damage during chemotherapy for acute leukemia and bone marrow transplant.

4. Evaluating the microbiome-tumor interactions in colorectal cancers.

5. Developing encapsulated microbial preparations to treat recurrent Clostridium difficile infections and other conditions.
