Nutrient and Phytochemical Analytics

Sign in to eRamp to place orders for the Nutrient and Phytochemical Analytics Shared Resource.


Our core brings unique expertise and world class LCMS instrumentation to analytical exploration of foods and biologics. We excel at targeted and untargeted metabolomics for biomarker identification and metabolite discovery. Metabolomics is an experimental capability providing unrivaled depth of metabolite coverage to enhance scientific rigor of investigations and competitiveness of grants. We have particular experience in metabolomics as applied to dietary interventions and support the OSU Discovery Themes in Personalized Food and Nutritional Metabolomics for Health.

NPASR goals

  • Provide investigators with bioanalytical method development and quantitative analysis of nutrients and phytochemicals in foods and their metabolites in biological samples
  • Enhance understanding of the role of dietary compounds in cancer prevention and control
  • Metabolite and biomarker discovery through untargeted LCMS metabolomics techniques 


Ken Riedl, PhD
Acting Director

Dr. Ken Riedl is an expert in analytical chemistry who develops and applies high-performance liquid chromatography (HPLC)-tandem mass spectrometry to the understanding of dietary food components in disease prevention and control. He operates three HPLC-mass spectrometry platforms, each with unique capabilities for identifying and quantifying phytochemicals and their metabolites. A broad background in food science, biochemistry and analytical chemistry strengthens his role in collaborative, multidisciplinary studies.  

Dr. Riedl studied food science at the University of Guelph in Ontario, Canada, where he received his undergraduate and master’s degrees. He earned his PhD in biochemistry from Miami University in Oxford, Ohio, investigating polyphenol-protein complexes as antioxidants. While a postdoctoral associate at Ohio State, he trained with Dr. Steven Schwartz to develop HPLC-MS skills toward quantitative phytochemical and metabolite analysis.

Morgan Cichon, PhD
Research Scientist

Dr. Morgan Cichon graduated from The Ohio State University with a Ph.D. in Food Science and expertise in untargeted metabolomics. She has an undergraduate degree in Chemistry from Emory University in Atlanta, GA. Morgan was hired as a research scientist under the Discovery Theme ‘Foods for Health’. Her thesis work focused on metabolomics experiments of both tomatoes and animal specimens from mice consuming various tomato diets. She is building LCMS platforms for physiological metabolite, lipidomics, and phytochemical and phytochemical metabolite analysis.

Steven Schwartz, PhD
Ex Officio

Steven Schwartz, PhD, was professor and holder of the Carl E. Haas Endowed Chair in Ohio State’s College of Food, Agricultural and Environmental Sciences, Department of Food Science and Technology. He also was a member of the Molecular Carcinogenesis and Chemoprevention Program at the OSUCCC – James, and directs the Center for Advanced Functional Foods Research and Entrepreneurship (CAFFRE) at Ohio State. In addition, Dr. Schwartz was a faculty member in the Interdisciplinary PhD Program in Nutrition (OSUN) in the College of Education and Human Ecology, Department of Human Nutrition.

Dr. Schwartz’s academic specialty centered 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 included chemistry of plant secondary metabolites, particularly chlorophylls, carotenoids and provitamin A nutrients. Dr. Schwartz earned his PhD in Environmental Toxicology and Food Science at the University of Wisconsin – Madison. He established NPASR in 2010 at the request of the OSUCCC.
