Dr. Cohen was the founding Director of the P30 Cincinnati Digestive Health Center: Bench to Bedside Research in Pediatric Digestive Diseases His research focused on the mechanism of action of E. coli heat stable enterotoxin, a worldwide cause of infant diarrhea. His laboratory identified that increased guanylyl cyclase (GC-C) receptors for this toxin contributed to the increased susceptibility and severity of diarrhea seen in infants. Identification of the endogenous ligands for GC-C, guanylin and uroguanylin, led to development of knockout mice and an evolving understanding of intestinal secretion and pharmacologic treatment through this ligand-receptor family. Dr. Cohen had a long-standing NIH-supported program of vaccine trials for enteric infection, including a validated human cholera challenge model which resulted in licensure of a cholera vaccine.
Dr. Cohen has held leadership positions in several professional capacities. He served as the only pediatrician on the NIH Commission on Digestive Diseases; he was chair of the Section on Growth, Development and Nutrition of the American Gastroenterological Association (AGA) and the Section on Gastroenterology, Hepatology and Nutrition (SOGHN) of the American Academy of Pediatrics; he was President of NASPGHAN, the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition. Dr. Cohen was elected to membership in the Association of American Physicians and has received several lifetime achievement awards, including the Shwachman Award from NASPGHAN, the Saul Horowitz Jr. Award from Mt.

Vanessa El Kamari
Instructor, Medicine - Infectious Diseases
BioVanessa El Kamari, MD, is a physician-scientist in the Division of Infectious Diseases and Geographic Medicine at Stanford University and a member of the David Relman Laboratory. Her research investigates how host–microbe interactions in the small intestine regulate mucosal immunity, barrier integrity, and systemic inflammation in autoimmune and inflammatory diseases.
Her current studies use non-invasive sampling of the small intestine in conditions such as celiac disease, multiple sclerosis, and environmental enteropathy. She applies an integrative, multi-omic approach—combining microbiology, immunology, molecular biology, and computational biology—to define spatial immune–microbial networks along the human gut.
Before joining Stanford, Dr. El Kamari’s research focused on inflammation and immune activation in chronic HIV infection, where she identified gut barrier dysfunction as a key driver of systemic inflammation and cardiometabolic complications. She also led intervention studies targeting immune activation and endothelial dysfunction in HIV, work that laid the foundation for her current efforts to apply similar mechanistic approaches to autoimmune and inflammatory disorders. -

Current Research and Scholarly InterestsThe microbiome carries out extraordinary feats of biology: it produces hundreds of molecules, many of which impact host physiology; modulates immune function potently and specifically; self-organizes biogeographically; and exhibits profound stability in the face of perturbations. Our lab studies the mechanisms of microbiome-host interactions. Our approach is based on two technologies we recently developed: a complex (119-member) defined gut community that serves as an analytically manageable but biologically relevant system for experimentation, and new genetic systems for common species from the microbiome. Using these systems, we investigate mechanisms at the community level and the strain level.
1) Community-level mechanisms. A typical gut microbiome consists of 200-250 bacterial species that span >6 orders of magnitude in relative abundance. As a system, these bacteria carry out extraordinary feats of metabolite consumption and production, elicit a variety of specific immune cell populations, self-organize geographically and metabolically, and exhibit profound resilience against a wide range of perturbations. Yet remarkably little is known about how the community functions as a system. We are exploring this by asking two broad questions: How do groups of organisms work together to influence immune function? What are the mechanisms that govern metabolism and ecology at the 100+ strain scale? Our goal is to learn rules that will enable us to design communities that solve specific therapeutic problems.
2) Strain-level mechanisms. Even though gut and skin colonists live in communities, individual strains can have an extraordinary impact on host biology. We focus on two broad (and partially overlapping) categories:
Immune modulation: Can we redirect colonist-specific T cells against an antigen of interest by expressing it on the surface of a bacterium? How do skin colonists induce high levels of Staphylococcus-specific antibodies in mice and humans?
Abundant microbiome-derived molecules: By constructing single-strain/single-gene knockouts in a complex defined community, we will ask: What are the effects of bacterially produced molecules on host metabolism and immunology? Can the molecular output of low-abundance organisms impact host physiology?
3) Cell and gene therapy. We have begun two new efforts in mammalian cell and gene therapies. First, we are developing methods that enable cell-type specific delivery of genome editing payloads in vivo. We are especially interested in delivery vehicles that are customizable and easy to manufacture. Second, we have begun a comprehensive genome mining effort with an emphasis on understudied or entirely novel enzyme systems with utility in mammalian genome editing.
