Dr. Robert Chapkin is a member of the Program in Integrative Nutrition & Complex Diseases, and Deputy Director of the NIEHS Center for Translational Environmental Health Research at Texas A&M University. He received his BS in Nutrition and Biochemistry from the University of Guelph, Ontario, Canada; an MS in Nutrition from the University of Guelph, 1983, and a PhD in Nutrition and Physiology Chemistry from the University of California-Davis in 1986. After completing a postdoctoral fellowship in Cancer Biology in the School of Medicine at the University of California-Davis in 1988, he joined the faculty at Texas A&M University.
Dr. Chapkin is currently a Distinguished Professor, Regents Professor and University Faculty Fellow and during the past 26 years has published over 220 peer-reviewed articles in nutrition, membrane biology, cancer biology, non-invasive biomarkers and immunology. He holds appointments in the Departments of Nutrition & Food Science, Biochemistry & Biophysics, Veterinary Integrated Biosciences, and Molecular Pathogenesis & Immunology.
Dr. Chapkin is an expert in environmental modulators related to chemoprevention of colon cancer and chronic inflammatory diseases, e.g., inflammatory bowel disease. He has been continuously funded by NIH/NCI for the past 25 years and has made highly significant contributions to T cell/inflammation biology and cancer chemoprevention in five specific areas: (i) membrane biology and nutritional modulation of epithelia/immune cell membrane structure and function, (ii) establishment of models for chronic inflammation and cancer prevention studies, (iii) elucidation of signal transduction processes in intestinal stem cells, (iv) investigation of the role of inflammation as a critical factor in cancer development, and its modulation by diet, and (v) development of novel noninvasive Systems Biology-based methodologies to assess crosstalk between the gut microbiome and the host transcriptome and its application to translational research. He serves as the Deputy Director of the P30 NIEHS sponsored Texas A&M Center for Translational Environmental Health Research (CTEHR) and coordinates the Quantitative Biology Core.
