Jodie Ouahed

Jodie Ouahed is an Assistant Professor at Harvard Medical School and an attending physician at the Inflammatory Bowel Disease (IBD) Center at Boston Children's Hospital. She serves as Director of the VEOIBD (Very Early Onset IBD) Clinic and is a member of the Precision Medicine Service at Boston Children's Hospital. Her clinical focus includes complex pediatric gastrointestinal conditions such as IBD, immune dysregulation disorders, and gastrointestinal motility disorders like gastroparesis.

Education:

• Bachelor's from McGill University (2003)
• MD from McGill University (2008)
• Pediatric Residency at McMaster Children’s Hospital (2011)
• Fellowship in Pediatric Gastroenterology at McMaster Children’s Hospital (2012)
• Advanced IBD Fellowship and Research Training at Boston Children's Hospital (2014–2015)
• Scholars in Clinical Sciences Program at Harvard Medical School (2014)

Research Interests: Dr. Ouahed's research explores the genetic and immunological mechanisms underlying early-onset IBD, particularly monogenic forms. She investigates epithelial barrier dysfunction, immune dysregulation pathways, and microbiome interactions in pediatric IBD. Her work bridges clinical care and precision medicine to tailor therapies for genetically defined IBD subtypes.

Publications Overview: Her recent work focuses on anti-TNF therapy efficacy in very early-onset IBD, epithelial contributions to monogenic IBD, and the role of bacterial sphingolipids in colitis pathogenesis. Her studies also address intestinal failure-associated inflammation and genetic immunodeficiencies linked to IBD.

Certifications:

• American Board of Pediatrics (General Pediatrics)
• American Board of Pediatrics (Pediatric Gastroenterology)

Labs/Teams: Active contributor to Boston Children’s Hospital’s IBD Center and Precision Medicine Service, collaborating on translational research and genomic medicine initiatives.
