|Peter Holt, MD
Senior Research Associate
Associate Director, Sackler Center for Biomedicine and Nutrition
Rockefeller University, USA
Dr. Peter Holt was born in Berlin, Germany, emigrated to the United Kingdom where he received his medical degree at the University of London. After a fellowship in gastroenterology at the Massachusettes General Hospital (Dr. Kurt Isselbacher) he became chief of gastroenterology at St. Luke’s Hospital, and then the combined St. Luke’s-Roosevelt Hospital Center. He rose to the rank of Professor of Medicine at Columbia University in 1975 and now is Emeritus Professor at that university. He also holds a position of Adjunct Professor at Weill Cornell Medical College.
Dr. Holt’s research interest has been centered on the function of epithelial cells of the gastrointestinal tract. His early work focused on mechanisms of lipid and bile salt absorption, and cellular metabolism and he was the first to clarify the physiology of the intestinal absorption of medium chain triglycerides and their application in the management of several gastrointestinal diseases. Later studies showing that colonic changes in aging resembled those found in the precancerous bowel led to research of biomarkers of risk and potential chemopreventive approaches for colorectal cancer risk reduction. Much of this focus was on effects of calcium and vitamin D (as well as folic acid) on the colon and their mechanism of action.
For the past decade, he has been a Senior Research Scientist at The Rockefeller University using its unique nutritional and metabolic facilities to conduct translational human studies in cancer prevention. In collaboration with investigators at Weill Cornell and Memorial Sloan Kettering Cancer Center, he has been studying how obesity increases the risk and the recurrence of colorectal and breast cancers. These studies focused on the role of inflammation and the potential preventive effects of anti-inflammatory approaches upon adipose tissues, skin, systemic metabolism and intestinal microbiota in obesity.

World-renowned pediatric gastroenterologist, research scientist, and entreprenuer Alessio Fasano, M.D. is the W. Allan Walker Chair of Pediatric Gastroenterology and Nutrition at Massachusetts General Hospital for Children and Professor of Pediatrics at Harvard Medical School. He is Division Chief of Pediatric Gastroentrology and Nutrition, Director of the Mucosal Immunology and Biology Research Center and Associate Chief for Basic, Clinical and Translational Research for the Department of Pediatrics at at the same Institution.
Trained in Naples, Italy, as a pediatric gastroenterologist, Dr. Fasano was recruited to the University of Maryland School of Medicine in 1993 and founded its Division of Pediatric Gastroenterology and Nutrition and remained at that Institution until he moved to MGHfC in January 2013. Dr. Fasano’s research expertise encompasses both basic science focused on bacterial pathogenesis, gut microbiome, regulation of gut permeability and intestinal mucosal biology and immunology, and translational science focused on the role of impaired intestinal barrier function in the pathogenesis of autoimmune and inflammatory diseases, including celiac disease and type 1 diabetes. Almost 15 years ago, Dr. Fasano’s lab discovered zonulin, a protein involved in the regulation of tight junctions and upregulated by changes in gut microbiome composition. Following this discovery, Dr. Fasano focused his major research interest in the pathophysiology of the paracellular pathway and structural changes of cell cytoskeleton and tight junctions induced by zonulin, its involvement in antigen trafficking and, ultimately development of chronic inflammatory diseases, including autoimmune, metabolic, and tumoral disorders, in genetically susceptible individuals. Dr. Fasano’s lab is currently investigating the composition and changes in the gastrointestinal microbiota to help determine why some individuals with an inherited predisposition to chronic inflammatory diseases develop clinical disease while others do not (Visit www.cdgemm.org).
Dr. Fasano is author of more than 280 peer reviewed manuscripts, he has been funded continuously by the National Institute of Health since 1996, is inventor of more than 160 patents, was co-founder of Alba Therapeutics, a company focused on developing synthetic peptides for the treatment of chronic inflammatory diseases (one of them, the zonulin inhibitor Larazotide acetate, is now entering phase III trial) and has received several awards, including the Shwachman award, the Linus Pauling Award, and the Entrepreneur of the year award and the Researcher of the year award from the University of Maryland.
Dr. Fasano has been featured in hundreds of media outlets including The New York Times, The Wall Street Journal, NPR, CNN, Bloomberg News, USA Today, Los Angeles Times, Huffington Post, Good Morning America, and Der Spiegel.
| Robert Hutkins, PhD
Professor, Department of Food Science and Technology
University of Nebraska- Lincoln, USA
Professor Bob Hutkins is the Khem Shahani Professor of Food Microbiology in the Food Science and Technology Department at the University of Nebraska-Lincoln. Before coming to UNL, he worked at Sanofi Bio Ingredients in Wisconsin and was a Postdoctoral Fellow at Boston University School of Medicine. He received his B.S. and M.S. degrees from the University of Missouri and his Ph.D. from the University of Minnesota.
The Hutkins Lab studies bacteria important in human health and in fermented foods. We are particularly interested in understanding: (1) factors affecting persistence and colonization of probiotic bacteria in the gastrointestinal tract; (2) how prebiotics shift the intestinal microbiota and metabolic activities in humans and animals; (3) how these shifts affect host health; and (4) how a combination of pro- and prebiotics (synbiotics) can enhance health outcomes. We address these questions using next generation sequencing, metagenomics, and other molecular techniques. Both clinical in vivo, as well as in vitro approaches are used. We are also interested in the specific molecular mechanisms and pathways used by probiotic lactic acid bacteria and bifidobacteria to metabolize prebiotic oligosaccharides. Finally, our group has begun to develop application strategies for incorporating prebiotics into foods.

|Jake Lusis, PhD
Professor, Departments of Microbiology Medicine
University of California- Los Angeles, USA
Aldons (Jake) Lusis is Professor of Microbiology, Human Genetics and Medicine at the University of California, Los Angeles. He obtained his Ph.D. in Biophysics from Oregon State University and did postdoctoral work in molecular genetics and mouse genetics in the laboratory of Ken Paigen at Roswell Park Memorial Institute prior to joining the faculty of UCLA.
His laboratory uses the combination of genetics, molecular biology, and informatics to investigate pathways underlying common cardiovascular and metabolic disorders. They exploit natural genetic variation among inbred strains of mice (and among human populations when possible) to identify novel targets and formulate hypotheses, and they perform validation using experimental perturbations in mice. A major focus has been the interactions of lipid metabolism and inflammation in cardiovascular disease and metabolic syndrome.
The laboratory has taken advantage of high throughput biologic technologies, such as transcriptomics, metabolomics, and proteomics, to help develop new approaches to understand complex traits. They have shown that when integrated with natural genetic variation, such multi-omics analyses can be used to model biologic pathways and uncover regulatory mechanisms, an approach known as “systems genetics”. They have recently applied this to understand host-gut microbiome interactions and how they contribute to cardio-metabolic disease.
During the past 10 years, they have developed a unique mapping approach in mice that is analogous to genome-wide association studies in humans. This approach utilizes a well-characterized population of 100 inbred strains of mice, termed the Hybrid Mouse Diversity Panel (HMDP). A major advantage of this approach is that the resolution is much better than with traditional genetic crosses. It also facilitates studies of gene-by-environment interactions, which are very difficult to address in human populations, and it has important advantages for systems-based approaches which require access to relevant tissues.

|Ian Sanderson, MD
Professor of Paediatric Gastroenterology
Queen Mary University of London, UK
Ian Sanderson first became interested in the intestine as a graduate student under Dr Dennis Parsons in Oxford where he examined the exit of absorbed amino acids from the enterocyte. After finishing his medical studies he worked as a house officer to Dr Anthony Dawson and trained as a paediatrician at the Hospitals for Sick Children, Great Ormond Street. He was the CICRA Clinical Research Fellow at St Bartholomew’s Hospital with Dr John Walker-Smith where he demonstrated that an elemental diet was as effective as high dose steroids in children with Crohn’s disease. He also showed that those taking the enteral feeds grew faster. After completing his training as a paediatrician and paediatric gastroenterologist, Professor Sanderson moved to Harvard Medical School as a Fulbright Scholar in Dr Allan Walker’s department. He became Assistant Professor of Pediatrics and Director of the Developmental Gastroenterology Laboratory at the Harvard Clinical Nutrition Research Centre. He developed the concept that luminal factors regulate genes in the epithelium that signal to the mucosal immune system. By this means, changes in diet can act through enterocytes altering inflammatory mechanisms in the intestine. Professor Sanderson was awarded the Crohn’s and Colitis Foundation of American Silver Jubilee award for his work in childhood Crohn’s disease and the Norman Kretchmer Award in Nutrition and Development for his work on the effect of diet on genes in the developing intestine. His current laboratory in London examines how diet affects the microbiota in Crohn’s disease; and how dietary factors act on genes in the epithelium both through promoter-based mechanisms and through changes in chromosomal structure.
Professor Sanderson was the first to show: (i) that the enterocyte has distinct transporters on the basolateral aspect for the exit of different amino acids (published 1980); (ii) that enteral feeds are as efficacious in treating children with Crohn’s disease as high dose steroids, while showing a significant benefit for growth (1987); (iii) that diet can regulate immune gene expression by the epithelium in vivo (1993); (iv) that short chain fatty acids (SCFA) regulate chemokine and IGF binding protein expression in enterocytes through histone acetylation (1997); (v) that breast milk contains Vascular endothelial growth factor (VEGF) in high concentrations, and that there is a VEGF receptor on the intestinal epithelial cell (1999); (vi) by epithelial cell-specific transgenic techniques, that chemokine expression by the intestinal epithelium orchestrates neutrophil and lymphocyte invasion in vivo (2001); (vii) that diet and age interact at the nuclear protein level to regulate gene expression (2004); (viii) that IL-6 mediates growth retardation in Crohn’s disease (2005); (ix) with Prof Tom MacDonald that colonic myofibroblasts enhance chemokine activity of the epithelial cell (2006); (x) that non-canonical Wnt signalling from colonic myofibroblasts enhances the repair of epithelial monolayers (2012) (xi) with Prof Petterson in Sweden, that persistent TLR signalling in the epithelial cells reduces the generation of new intestinal tumours in mice (2014). As a clinician he has also published many observations, including being the first to describe four new diseases of childhood, two of which involve inflammation in the GI tract.

|Sathish Subramanian, MD, PhD
Resident, Department of Medicine
Massachusetts General Hospital, USA
Sathish Subramanian completed his MD, PhD at Washington University in St. Louis School of Medicine under the guidance of Dr. Jeffrey I. Gordon where he, along with colleagues in Bangladesh, used high-throughput sequencing and machine-learning methods to demonstrate that healthy children share a signature of healthy gut bacteria development that appears to be conserved between different unrelated individuals and populations, despite varying physical environments, culinary traditions and ancestry. His work also revealed that gut bacterial development in undernourished children lag behind their healthy peers and are not promoted by currently available therapeutic foods.
Sathish is originally from Zambia and holds degrees from the University of Pennsylvania as a Roy and Diana Vagelos scholar and University of Cambridge as a Gates Cambridge scholar. He is currently a resident of the Stanbury Physician-Scientist Pathway in the Department of Medicine at the Massachusetts General Hospital.

|Gary Wu, MD
Ferdinand G. Weisbrod Professor in Gastroenterology
University of Pennsylvania School of Medicine, USA
Dr. Wu is the Ferdinand G. Weisbrod Professor in Gastroenterology at the Perelman School of Medicine at the University of Pennsylvania where he is the Associate Chief for Research in the Division of Gastroenterology and is also the Associate Director of the Center for Molecular Studies in Digestive and Liver Disease.
