Patient Age Group

Edit Profile


Dr. Buie's medical practice is in pediatric gastroenterology. Since 1990 he has worked in clinical medicine primarily, but his practice has evolved to include teaching and clinical research as well. From 1990 to 1998, he practiced at Pediatric Gastroenterology Associates. In 1998, he joined MGH and Harvard Medical School. A unique aspect of his practice is that a large percent of children he treats have developmental disorders, primarily autism. He has practiced the Lurie Center for the past 10 years as one of few gastroenterologists situated in a developmental clinic in the country.

He has cared for children from over 40 states in the U.S. and from all over the world. In 2009 Dr. Buie was honored by the Autism Society of America as Professional of the Year for his outstanding work.

As Dr. Buie's clinical experience grew, he has enjoyed the opportunity to become an educator as well. He has created a tangible educational program and teaching curricula presented nationally and internationally. His teaching series  includes guidelines regarding behaviors of children with autism that may represent pain or other underlying medical issues and has been presented to parents; physical, occupational, and speech therapists; and a wide range of specialists from the medical community. The usefulness and popularity of Dr. Buie's lectures is shown by the repeated requests to speak to parents (Autism Society of America and Defeat Autism Now), educators (Learning and the Brain) and physicians (pediatric and physician conferences at universities and medical centers throughout the United States).

Research & Publications

Research Summary
Dr. Buie's distinct patient population and development of collaborative initiatives with other physicians have provided a foundation for his involvement in research as well as his extensive clinical practice. He is a founding developer of the Autism Treatment Network, an organization that created a collaboration of major autism research programs to standardize the evaluation and medical care of children with autism spectrum disorders. Initially a 5- center program, ATN has grown to include 15 academic programs that participate in this program, which is now funded by AutismSpeaks. Dr. Buie's current research involves collaboration with several physicians at Massachusetts General Hospital and Harvard University as well as Columbia University, Baylor College of Medicine, USC, and Vanderbilt University.
