Patrick M. Gillevet

Patrick M. Gillevet is a Professor and Director of the Microbiome Analysis Center at George Mason University, with a primary appointment in the Biology Department and affiliate faculty status in the School of Systems Biology. His career focuses on integrating genomics, bioinformatics, and molecular ecology to study microbiome interactions in human health and environmental systems, including the development of multitag sequencing for high-throughput microbial analysis.

• Education:
  • Ph.D., Biochemistry, University of Manitoba (1982)
  • B.S., Microbiology, University of Toronto (1976)

His research explores dysbiosis in the human microbiome (gut, mouth, urogenital, respiratory tracts) and its role in diseases, cognitive function, and social behavior. He pioneered the concept of the "metabiome" to describe host-microbiome interactions in systems biology. Key projects include analyzing multitag sequencing for evolutionary studies and microbial community characterization in ecosystems.

Recent publications highlight collaborations on gut microbiome trends in cirrhosis, alcohol use disorder, and antibiotic resistance, with a focus on cross-sectional and longitudinal analyses. His work spans clinical trials (e.g., griffithsin gel), dietary interventions, and environmental microbiome studies.
