My research overlaps with this clinical interest through participation in ImproveCareNow, a collaborative chronic care network that focuses on improving care and health of children with ulcerative colitis and Crohn’s disease, and in several clinical studies that will advance understanding of these complex diseases and better direct clinical care.
