He received his medical degree from the University of Utah, did internal medicine training at Barnes Hospital, Washington University in St. Louis, and GI fellowship training at the University of Utah. His career has focused on familial risk and genetics of colon cancer. He was part of the group that discovered the APC gene, the gene responsible for FAP when mutated and also the first gene mutated in over 85% of all colon cancers. Dr. Burt has been a leader in the application of genetic testing to colon cancer syndromes, syndrome phenotype description, syndrome clinical management and syndrome chemoprevention. His CV includes 112 original journal articles, 86 reviews and 49 book chapters and books and numerous abstracts.

His clinical and research interests are in the area of hereditary colorectal cancer and the polyposis syndromes in children and adolescents. He has conducted laboratory research using rodent models to understand basic processes in gastroenterology and the pathophysiology of polyposis syndromes. Polyamine metabolism has been of long-standing interest, dating back to his Fellowship at the University of Nebraska and later at The University of Arizona in Tucson. In a collaborative effort, published in Carcinogenesis in 1999, he helped provided the first evidence documenting alterations in intestinal and colonic polyamine metabolism in the ApcMin/+ mouse model of Familial Adenomatous Polyposis (FAP). This study provided early rationale for targeting polyamine metabolism in patients with FAP.
