BiographyDr. Dey is the founding director of molecular nutrition and nutrigenomics research at SDSU and teaches related courses in undergraduate and graduate-level nutrition-dietetics classes. The increasing burden of chronic diseases creates a more significant gap between health span and lifespan which has many negative socioeconomic implications. Food provides our body with the instructions that it needs to function. With uninterrupted competitive funding and leading multi-disciplinary research as a principal investigator for over two decades, Dr. Dey's research has focused on understanding how responses to dietary factors link across levels of human systems biology i.e., studying physical, biochemical, physiological, and multi-omics-based endpoints across the lifecycle. Dr. Dey has served on journal editorial boards, and on many internal and external advisory and grant review panels (e.g. NIH, USDA, FFAR, DoD, etc.). Some 40 researchers, including graduate (Ph.D. and MS) and undergraduate students as well as postdoctoral scholars, have received funding, research training at the interface of nutrition and biomedical sciences, and mentoring toward professional development in Dr. Dey’s lab. In Dey-lab, researchers learn how to perform as high-functioning, collaborative team members, acquire critical and analytical skills, problem-solving proficiency, and an ability to learn quickly and function independently. Mentored research in Dey-lab has resulted in nine coveted recognitions between 2014-2022, including some of the most prestigious awards in the nutrition science field from the American Society for Nutrition.

Food can be the most powerful medicine, especially for the mitigation of chronic disease burdens. However, knowledge gaps in understanding optimal dietary patterns for different life stages can create confusion and consumer misperceptions. We combine cell and animal model research for mechanistic discoveries with clinical research (registered trials) for addressing translational challenges to help advance the next generation of nutritional health knowledge. Our five key scientific areas of contribution are:
-- Five human subject studies related to healthspan promotion using high-quality or habitual diets under controlled intervention conditions to generate definitive outcomes related to metabolic phenotypes of diet and gut microbiota interactions in adults and older adults in South Dakota.
-- A role of maternal diet in shaping offspring cardiometabolic health in-utero through epigenetically regulated cardiac gene expression.
-- Elucidation of biological activities and underlying molecular mechanisms of anti-inflammatory and chemo-preventive dietary compounds in rodent models for human diseases.
-- Designed a cell-based high-content platform for screening biologically active nutraceuticals.
-- As part of the Comparative Genomics Consortium, developed genotype to phenotype discovery tools and value-added agricultural products (doctoral & postdoc training).
