Scientific Advisory Committee

The Scientific Advisory Committee (SAC) guides the scientific and technical content, and priorities for the consortium’s activities such as the annual Symposium. The SAC is composed of the Scientific Advisory Committee Chair and at least five other representatives from the scientific community. 

J. Bruce German, Ph.D.
Director, Foods for Health Institute
Professor, Department of Food Science & Technology
University of California Davis, Davis, CA, USA

Dr. German, is the current Chair of the IMGC’s Scientific Advisory Committee. He established the IMGC in 2003 and organized the IMGC Symposia, first in Napa California, and then at various sites around the international scientific community. He has co-directed the IMGC programs and Symposia through the present. He has engaged in active collaborations with IMGC scientists around the world published over 100 publications with IMGC colleagues and launched products and technologies into the commercial marketplace. Dr. German is a Professor in the Department of Food Science and Technology and Director of the Foods for Health Institute at the University of California Davis. He holds a Ph.D. degree in Food Chemistry from Cornell University. He has studied milk and lactation for over 30 years to understand how milk nourishes, protects and assists in the development of mammalian infants.  Dr. German has used mammalian milk as a scientific and strategic model to understand the potential for diet to act on many aspects of human health. To that goal, he has championed the development of genomics, proteomics and metabolomics tools to the explicit objective of understanding milk. Among the themes that have emerged from that research is the conspicuously personal aspect of milk in guiding the development of each infant. That theme has been the basis of long term research into the precision of nutrition and the importance of a more personalized approach to diet and health both scientifically and through public policy. The research group that Dr. German leads has published over 450 articles, which have been cited over 38,000 times. Dr. German led the large team of faculty who made the mechanistic, clinical and regulatory discoveries that Bifidobacterium longum subspecies infantis is the ancestral bacterium in breastfed infants. The implications of those discoveries led the faculty to co-found a company to provide this bacterium to recolonize babies born by cesarean section or maternal lineages exposed to antibiotics. Dr. German has given over 250 lectures on the science of milk. His bibliography is publicly available here.

Nurit Argov-Argaman, Ph.D.
Assistant Professor, Department of Animal sciences
The Robert H Smith Faculty of Agriculture, Food and Environment
The Hebrew University of Jerusalem, Israel

Dr. Nurit Argov-Argaman joined the IMGC Scientific Advisory Committee in 2020 and has participated in IMGC Symposia for more than a decade. She trained at The Hebrew University of Jerusalem in nutrition and lipid metabolism. After completing her post-doctoral fellowship at the University of California Davis, she returned to the Hebrew University of Jerusalem in Israel and created her lactation and metabolism research group. Her research focus is lactation physiology and its metabolic regulation. The objective of her research group is to obtain knowledge on the nutritional and metabolic regulation of milk fat composition, concentration, and structure. Her research group discovered the role of the mitochondria in regulating the milk fat globule structure and hence the composition of milk fat. Since the mitochondria is susceptible to bioitic and abiotic stressors, her studies have been focusing on the effect of environmental stress on the milk composition and lactation traits of dairy animals and finding nutritional strategies to mitigate these environmental detrimental effects. In her studies, she found strong associations between the milk fat structure and milk composition and hence focuses on the effect of the milk fat structure, e.g. the milk fat globule, on product quality. This association is studied under two aspects: 1) product stability and quality in terms of the content of bioactive constituents, and 2) the effect on the health of the consumer in terms of the digestion and absorption, physiological, immune and metabolic response to milk with varying milk fat globule sizes. Besides this research, Dr. Argov-Argaman develops, and teaches multiple rigorous courses in the BSc and MSc programs in The Animal Science Department of the Hebrew University of Jerusalem, with an emphasis on lactation physiology, animal nutrition and lipid metabolism. Her bibliography is publicly available here.
