Chiazotam Ekekezie
Clinical Assistant Professor, Medicine - Gastroenterology & Hepatology
BioPrior to Stanford, Dr Ekekezie completed internal medicine training and chief residency at Brown University. She moved to Stanford for GI and hepatology fellowship, and served as a chief fellow in her final year. After fellowship, she stayed on joining as a Clinical Assistant Professor and Associate Program Director for the GI fellowship program. She has presented nationally and internationally on topics related to medical education, psychological safety, and inclusion.
Clinically, Dr Ekekezie welcomes seeing patients with a diverse range of GI-related issues as part of Stanford’s general GI group. She is dedicated to advancing a career in academic medicine that is balanced on her “core-four” pillars: humanism-centered patient care, community-engaged advocacy, service-oriented leadership, and mentoring the next generation of clinicians. She has received numerous awards for excellence in patient care, professionalism, communication, and collaborative consultation, as well as for her skills as an effective leader, mentor, and educator. -
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. -

Samer Eldika
Clinical Professor, Medicine - Gastroenterology & Hepatology
BioDr. Eldika received his medical education at the American University of Beirut. He completed his General Gastroenterology Fellowship at the State University of New York in Buffalo and Advanced Endoscopy Fellowship at the University of Virginia. At Ohio State University, he served as the Director of Interventional Endoscopy and Endoscopic Quality. His time at Ohio State University contributed to the growth and maturity of his experience and skills in interventional endoscopy. During his tenure there, he played a major role in building the program of interventional endoscopy in general, as well as interventional endoscopy for the pediatric age group, and the endoscopic quality program. Over the years, he was involved in training several gastroenterology fellows and interventional endoscopists. He recently joined Stanford University where he continues to practice interventional endoscopy and train fellows.
He is a board-certified Gastroenterologist with clinical interests in pancreaticobiliary diseases, gastrointestinal neoplasia, and related interventional endoscopic procedures. As an endoscopist, he has extensive experience in performing a variety of interventional endoscopic procedures. These procedures include endoscopic ultrasound (EUS)-guided procedures like fine needle aspiration/biopsy, injections, fiducial placement, pseudocyst drainage/necrosectomy, biliary drainage, gastrojejunostomy, transgastric ERCP, and needle-based confocal endomicroscopy for the evaluation of pancreatic cystic lesions. He also performs endoscopic retrograde cholangiopancreatography (ERCP), endoscopic mucosal resection, enteral and stenting, enteral feeding tube placement, as well as deep enteroscopy.
His research interest evolves around interventional endoscopy, more specifically in the evaluation of pancreatic cystic lesions. Dr. Eldika has received multiple awards in his career, his most recent one being the “Reviewer Award, April 2020,” for his superior contributions to the journal of Gastrointestinal Endoscopy, both through completing high numbers of reviews and for submitting the highest quality of work.
Dr. Eldika is a fellow of the American Society of Gastrointestinal Endoscopy. He is a member of the American Gastroenterological Association, American College of Gastroenterology, and American Pancreatic Association.
When not working Dr. Eldika enjoys reading, listening to music, watching sports and walking in nature.
