My research interests are primarily focused on long-term outcomes of patients born with Hirschsprung disease, imperforate anus, cloaca anomaly, idiopathic constipation, and colorectal problems. The surgical reconstruction and associated malformations. I also believe in education and helping other countries to achieve excellence upon treatment of these conditions.

Clinical Interests
My many clinical interests include congenital colorectal problems such as Anorectal and Urogenital malformation (imperforate anus, cloaca, cloacal exstrophy, vaginal agenesis); Hirschsprung Disease; Total Colonic Aganglionosis; Bowel Management (fecal incontinence and idiopathic constipation).
Care Philosophy
I strive to provide the best surgical and clinical care for my patients. I believe in devoting time to patients and family explaining and discussing prognosis, long-term expectations as well as surgical reconstruction and possible future implications. I also believe in following our patients throughout life.
Personal Interests
In my spare time, I enjoy spending time with family, watching good movies, and practicing outside sports (running, biking, swimming). I also enjoy traveling the world to try to improve colorectal care for children everywhere.
Volunteer Activities
Traveling the world to try to improve colorectal care everywhere. I have traveled to more than 30 different countries to give lectures and live surgical demonstrations on how to treat congenital colorectal problems.
Public Speaking Yes
Surgical Treatment of Colorectal Problems in Children. From prenatal to long-term outcomes. 3-day intensive workshop with live surgical demonstrations.
