After that, he worked as a scientist in the Clinical Chemistry and Haematology Laboratory of Gelderse Vallei Hospital, where he headed the clinical mass spectrometry laboratory and developed a dietary advice tool to improve micronutrient intake for use in healthcare settings.
His current work focuses on developing and applying new analytical methods to study nutrient absorption, metabolism and excretion, with particular interest in micronutrient status. This includes studying micronutrient status and malnutrition in patients that are at risk of deficiencies. Michiel teaches about nutritional biomarkers in the BSc, MSc and post-graduate education programs of Wageningen University, and coordinates a course in Pharmacology and Nutrition. He has published research papers, reviews and book chapters on nutritional biochemistry, biomarkers and vitamins, and is a member of the Dutch Association of Clinical Chemistry (NVKC).

Susanne Bügel. MSc, PhD
Professor, Deputy Head of Department
Department of Nutrition, Exercise and Sports. University of Copenhagen, Denmark.
Susanne Bügel graduated from University of southern Denmark in 1990 and got her Phd from the same university in 1994. SB is today professor in Human Nutrition at the Department of Nutrition, Exercise and Sports at University of Copenhagen. She works with nutrition in human health, primarily performing randomized controlled human interventions. The areas of expertise include micronutrients; vitamins and minerals for optimal health, primary food production and effects of processing. Currently SB focus on projects about health aspects of sustainable food systems and diets.

Isis Trujillo-Gonzalez, PhD
Assistant Professor
Dr. Isis Trujillo-Gonzalez is a Research Assistant Professor at the Nutrition Research Institute, UNC-Chapel Hill. Her research focuses on the critical role of choline, employing cutting-edge molecular and neuroscience methodologies to explore its impact on brain development, particularly during the prenatal period.
Her lab investigates how maternal choline intake influences typical and atypical brain development, with implications for neurodevelopmental disorders. Additionally, she is interested in choline’s broader effects on metabolic health and its potential links to neurodegenerative diseases. Dr. Trujillo-Gonzalez holds a PhD in Biomedical Science from the National University of Mexico.

Jens Lykkesfeldt
Dr. Lykkesfeldt holds a MSc degree in organic chemistry (1989), a PhD degree in biochemistry (1992) and a DSc degree in medicine in 2005 for his dissertation on the effect of smoking on vitamin C status. He spent two 3-yr postdocs at University of Copenhagen and UC Berkeley, respectively, the latter with Professor Bruce N. Ames. In 1998, he became PI and in 2008, he was appointed professor and chair in pharmacology and toxicology at the Faculty of Health and Medical Sciences, University of Copenhagen, which is his current position. Dr. Lykkesfeldt’s research interests include the roles of oxidative stress and antioxidants in early development, chronic diseases and aging, in particular that of vitamin C, and has resulted in >100 articles on vitamin C alone.
In 2008, he received the Catherine Pasquiere award from the Society for Free Radical Research, Europe, and was newly appointed inaugural Excellence in Nutrition Fellow of the American Society of Nutrition for his work on vitamin C. Dr. Lykkesfeldt has been lead author on several influential papers on vitamin C pharmacokinetics and its role in health and disease and engaged in advising authorities on vitamin C recommendations for optimal health.

Gregory J Brewer, UC Irvine, California
Brewer is Professor of Neuroengineering at University of California Irvine since 2013. Before that, he was Professor of Cell Biology and Neurology at Southern Illinois University School of Medicine for 33 years. He trained at Caltech, UC San Diego and MIT.
He has advanced the field of aging neurobiology with primary neuron cell culture in serum-free defined medium that enables extraction, regeneration and maturation of neurons from any age rodent or human. This technology has enabled age-related comparisons across the age-span and between different mouse genotypes in constant culture conditions. His research has led him to detect age-related bioenergetic deficits and excess ROS, which he plans to treat with nicotinamide.
