She is an editor-in-chief of the book Your Child with Inflammatory Bowel Disease: A Family Guide for Caregiving (JHU Press).

Her clinical practice focuses on inflammatory intestinal disorders such as IBD, autoimmune enteropathy, celiac disease and eosinophilic gastroenteritis.

She is highly respected among her peers and provides second opinions for patients referred to her from throughout the United States.
