Biography

Rachel Kopec joined Ohio State as an assistant professor in Autumn 2016 under the Discovery Themes Initiative “Foods for Health and Metabolomics.” Her lab uses model systems (foods and food processing, Caco-2 intestinal cells, animals) and actual humans in combination with analytical chemistry tools (LC-PDA, LC-MS/MS, untargeted metabolomics) to decipher nutrient/nutrient and nutrient-bioactive interactions. Her group focuses on the interactions that occur with fat-soluble vitamins and phytochemicals (i.e. omega-3 fatty acids, carotenoids, chlorophylls). 

Because the currently available metabolomics tools provide a lot of data with limited interpretability (i.e. limited ability to “make meaning” from the data), her group also collaborates to develop new tools to aid in the identification of unknown metabolites, and to integrate multi “omic” platforms (to leverage knowledge about genes and microorganisms growing in/on human bodies with known shifts in metabolism inside the body).
