Leon Schurgers is professor of biochemistry of vascular calcification and vice chair of the department of biochemistry, which is part of the Cardiovascular Research Institute CARIM, Maastricht University. He also is chair of the Stem Cell Reseach University Maastricht (SCRUM). His work includes molecular biology, biochemistry, experimental animal, pharmacology, and clinical studies in the fields of cardiovascular disease. He is leading the scientific part on vascular smooth muscle cells and iPSCs, as well as the role of vitamin K-metabolism in health and vascular disease.

His project line aims to elucidate the molecular mechanisms of vascular smooth muscle cells (SMCs) by which vascular calcification is initiated and propagated: key cellular events include phenotypic switching and formation of extracellular vesicles contributing to the initiation and progression of calcification. The regulation of vitamin K-dependent protein biosynthesis, its sites of action and its putative relationship with calcification is insufficient to understand the pathogenesis of vascular calcification at a level that allows the development of novel diagnostic tools and therapeutic strategies.

Importantly, these findings will help to understand the paradoxal observation that patients with low vitamin K-status during oral anticoagulant treatment develop extensive vascular calcification and might provide new insights in prognostic and preventive measures.

Michael Green received a B.A. in Physiology (1967) and a Ph.D. in Nutritional Sciences (1973) from the University of California, Berkeley, before doing post-doctoral research at Cornell University.  In 1975, he joined the faculty in nutrition at Penn State University, spending the next 42 years teaching at the undergraduate and graduate level; doing research and mentoring students and junior colleagues; and serving several times as department chair.  He retired in 2017 but, as professor emeritus, has maintained an active and productive research program.


Following an early interest in kinetics, Green has become one of a small group of nutrition scientists who have been trained in and extensively use the Simulation, Analysis and Modeling software (WinSAAM) to describe and quantitate the kinetics and metabolism of biologically interesting substances.  At Penn State, his research focused on applying model-based compartmental analysis to advance knowledge related to vitamin A status and metabolism in various nutritional and physiological states in both animal models and humans, and he has collaborated with others to apply modeling to other systems.  During his academic career, he was a visiting scientist/scholar at several other institutions including NIH’s Laboratory for Mathematical Biology, University of Oslo’s Institute for Nutrition Research (Fulbright Research Scholar), University of Pennsylvania’s School of Veterinary Medicine, Karolinska Institutet’s Institute for Environmental Medicine, and Newcastle University’s School of Agriculture, Food and Rural Development.  Currently, he is collaborating with colleagues at the University of California, Davis; Universidad de Sonora, Sonora, Mexico; and Wageningen University & Research, Division of Human Nutrition and Health, Wageningen, Netherlands, and he has been/is involved in multi-site international studies on vitamin A status funded by the Gates Foundation and the International Atomic Energy Agency.  Over the course of his career, Green was invited to make presentations at numerous national and international conferences and was honored to present the James Allen Olson memorial lecture for the American Society for Nutrition’s Carotenoids and Retinoids Interactive Group in 2022.  Green is lead- or co-author on >100 peer-reviewed publications, more than 30 of which were published after his formal retirement and including one non-modeling article which argued that, contrary to conventional wisdom, fatty acids are indeed a gluconeogenic precursor.  He continues to share his modeling expertise with younger colleagues and students through a weekly online “modeling club.”


Dr. Green’s presentation at IVC will focus on how model-based compartmental analysis is being used to study the movement (kinetics) of vitamin A and provitamin A-carotenoids in real and theoretical humans.

Nanna Roos

Nanna Roos is Associated Professor in human nutrition at University of Copenhagen, with a long-term research focus on the role of animal-source foods for enhancing dietary quality - including as sources of micronutrients - in diets in populations vulnerable to undernutrition in Asia and Africa.

The early research documented that certain small indigenous fish in Bangladesh were particularly rich in vitamin A, which could enrich the nutritional outputs of local fish farms. In Cambodia, NR investigated the use of locally processed small fish for developing processed food products for the prevention and treatment of undernutrition in infants and young children. Currently, NR is leading research in Bangladesh focusing on understanding the linkages between the health and nutrition of young women - including micronutrient status - and a complex coastal aquatic food environment formed around the production of high-value shrimp for export. NR is engaged in the agenda about dietary transition to more sustainable diets by focusing research on edible insects as alternative animal protein sources.

Yasmine J. Liu, Ph.D.

Dr. Liu is a postdoctoral fellow in the group of Prof. Johan Auwerx at École polytechnique fédérale de Lausanne (EPFL, Switzerland). Dr. Liu received a M.S. in Beijing Normal University, China in Biological Sciences, and a Ph.D. in University of Amsterdam (UvA), Amsterdam in Biomedical Sciences.

The Auwerx lab has been focused on the mapping of signaling networks and pathways that govern mitochondrial function and as such regulate organismal metabolism and aging. Particularly, the work from Auwerx team contributed to transforming NAD+ from its classic function as a cofactor for redox reactions into active signaling molecule that regulate mitochondrial function and metabolism. These studies also indicated that replenishing cellular NAD+ stores is an effective strategy to treat diseases that are characterized by defective NAD+ homeostasis and to enhance health- and lifespan. After joining the Auwerx team in 2021, Dr. Liu led the NAD+ research effort to compare the therapeutic efficacy of various NAD+ boosters in NAFLD/NASH. In a mouse model with high relevance to human NAFLD/NASH, she applied a robust clinical phenotyping scheme and a multi-layered omics approach. By leveraging the background of her and Auwerx lab in molecular biology, physiology, and bioinformatics, she aims to reveal the metabolic significance of various NAD+ boosters that engage different molecular targets and importantly to identify and prioritize the effective NAD+ therapy for human NAFLD/NASH.
