Director: Steven J. Schwartz, PhD
Associate Director: Ken M. Riedl, PhD

Steven J. Schwartz, PhD, is the director of the Nutrient and Phytochemical Analytic Shared Resource (NAPSR) as well as a member of the Molecular Carcinogenesis and Chemoprevention Group within the OSUCCC – James. Dr. Schwartz is a Professor and Carl E. Haas Endowed Chair in the College of Food, Agriculture & Environmental Science, Department of Food Science and Technology. He also serves as the director of the Center for Advanced Functional Foods Research and Entrepreneurship (CAFFRE) and a faculty member, Interdisciplinary PhD Program in Nutrition (OSUN) in the College of Education and Human Ecology, Department of Human Nutrition.

Dr. Schwartz’s academic specialty centers on bioavailability, metabolism and physiological significance of phytochemicals, with particular emphasis on nutrients, phytochemicals and bioactive components in foods related to chronic disease, oxidative stress and cancer prevention and control. Other interests include chemistry of plant secondary metabolites, particularly chlorophylls, carotenoids and provitamin A nutrients. 

Dr. Schwartz received his undergraduate degree in Chemistry at SUNY – Stony Brook and doctoral degree in Environmental Toxicology and Food Science from the University of Wisconsin – Madison.

Ken M. Riedl, PhD, is the associate director of NPASR. Dr. Riedl’s expertise lies in the field of analytical chemistry where he develops and applies HPLC-tandem mass spectrometry toward an understanding of dietary food components in disease prevention and control. Currently he functions as a research scientist operating three different HPLC-MS platforms, each with unique capabilities for identifying and quantifying phytochemicals and their metabolites. A broad background in food science, biochemistry and analytical chemistry facilitates his role in collaborative efforts spanning disciplines from horticulture to nutrition and clinical research.

Dr. Riedl studied Food Science at the University of Guelph in Ontario, Canada where he earned both his bachelor’s and master’s degrees. He earned his PhD in Biochemistry from Miami University in Oxford, Ohio, investigating polyphenol-protein complexes as antioxidants. As a postdoctoral associate he trained with Dr. Schwartz to develop HPLC-MS/MS skills toward quantitative phytochemical and metabolite analysis.
