About Me

Dr. Patterson is the Tombros Early Career Professor, Professor of Molecular Toxicology, and Professor of Biochemistry and Molecular Biology at the Pennsylvania State University, University Park, PA and is the Scientific Director of Metabolomics. He holds joint appointments in the Department of Veterinary and Biomedical Sciences and the Department of Biochemistry and Molecular Biology. He received his BS in Microbiology from the Pennsylvania State University and his PhD from the Graduate Partnerships Program between the National Cancer Institute and George Washington University. Dr. Patterson did his postdoctoral fellowship in the Lab of Metabolism under Dr. Frank J. Gonzalez.

Research Summary

Dr. Patterson and his students, postdocs, and collaborators focus on understanding the host-metabolite-microbiota communication network—specifically how the manipulation of gut microbiota by diet and/or xenobiotics impacts host metabolites (e.g., bile acids, short chain fatty acids), their metabolism, and how these co-metabolites interact with host ligand-activated transcription factors. The lab employs a variety of tools, including NMR- and mass spectrometry-based metabolomics, genomics, and conventional and gnotobiotic transgenic mice, to facilitate its study of these pathways and understand their impact on human health and disease.  

Dr. Patterson teaches VB SC 230: The Science of Poisons which serves as the introductory course for the Toxicology major, guiding students as they examine important principles, such as dose-response and routes and sites of exposure, as well as mechanisms of toxicity, including delivery, chemical interactions, and resultant toxicities.
