Mallory Chavannes

Mallory Chavannes is an Assistant Professor of Clinical Pediatrics at the University of Southern California (USC). Her work focuses on pediatric gastroenterology, with a strong emphasis on inflammatory bowel disease (IBD) and innovative diagnostic methods such as intestinal ultrasound. She contributes to clinical guidelines and expert consensus efforts, particularly through the International Bowel Ultrasound Group (IBUS) Pediatric Committee. Her research spans personalized nutrition therapies, artificial intelligence in medical imaging, and the integration of behavioral health into subspecialty care.

Dr. Chavannes has published extensively on IBD monitoring, including studies on bowel wall thickness assessment in remission, fecal calprotectin biomarkers, and the role of ultrasound in pediatric disease management. Her work also addresses healthcare policy and cost-effectiveness of diagnostics, as seen in her analysis of primary care IBD diagnosis strategies. She has collaborated on multi-centered cohort studies, such as investigating ustekinumab for refractory Crohn’s disease in children.

Her research highlights include advancing non-invasive imaging techniques, exploring diet’s role in IBD through N-of-1 trials, and understanding microbiome-nutrition interactions in pediatric patients. While no specific awards are listed, her contributions to clinical and translational research in IBD are notable. She advises no listed students but collaborates on grants focused on pediatric IBD and imaging technologies. No affiliated labs or teams are explicitly mentioned in the provided text.
