Professor Frank graduated with a Diploma in Nutrition from Bonn University (2000), obtained a PhD in Food Science at the Swedish University of Agricultural Sciences (2004), and received postdoctoral training at the Universities of Kiel and Hohenheim. He was a visiting scientist at the Linus Pauling Institute (USA), the University of Reading (UK) and the University of Surrey (UK).
Dr Frank was appointed Professor of Human Metabolomics at the Institute of Nutritional and Food Sciences at the University of Bonn in 2012 and, in 2013, Full Professor and head of the division Biofunctionality and Safety of Food at the Institute of Biological Chemistry and Nutrition at the University of Hohenheim.
He is president of the Society of Nutrition and Food Science, acting president of the Gesellschaft für angewandte Vitaminforschung, and editor-in-chief of NFS Journal, regional co-editor of Nutrition, and member of the editorial boards of The Journal of Nutritional Biochemistry, BioFactors, and Plant Foods for Human Nutrition.
His research interests lie in factors that determine the absorption, metabolism, and elimination of phytochemicals and the different vitamin E congeners and in developing novel strategies to overcome the low intrinsic oral bioavailability of phytochemicals, as well as in understanding the biological activities of potentially health-beneficial bioactives.
