Omics Leadership

Omics Facility core co-leaders

Jon Chorover, PhD
Dr. Chorover, Professor and Department Head of Environmental Chemistry in the Department of Environmental Science, is primarily responsible for meeting with SWEHSC investigators to design experiments, interpret data, and achieve research objectives. He has over 180 publications on biogeochemical processes occurring in soil, sediment, and water and is OFC Co-Director of the Exposomics lab. Dr. Chorover’s areas of expertise include components and processes that influence the form and mobility of metals and organics in the Earth’s near-surface environment.

James Galligan, PhD
Dr. Galligan is an Assistant Professor in the Department of Pharmacology and Toxicology, where he studies the links between cellular metabolism, environmental genetics and disease etiology. His research focuses on post-translational modifications and reactive metabolites that are deleterious to cell health. Dr. Galligan provides his expertise to Center investigators in the selection of experimental approaches, methodological details, and interpretation of results.

George Watts, PhD 
Dr. Watts is an Associate Research Professor in the Department of Pharmacology and managing OFC Co-Director of the Genomics lab. Dr. Watts provides consultation with SWEHSC investigators on experimental design and technology choice, performs data analysis, and oversees new service development for investigators. He has over 20 years of experience in research on the environmental effects of epigenetics, genomics, and the microbiome. Dr. Watts has been collaborating with SWEHSC investigators for over 15 years on genomics projects resulting in over 20 collaborative authorships.
