His specific clinical interests include robotic rectal cancer surgery, Crohn’s/inflammatory bowel disease, sphincter sparing anal fistula surgery (LIFT) procedure and abdominopelvic reoperative surgery. He has a keen interest in research and is an author on numerous publications in peer-reviewed journals, published abstracts, oral presentations and book chapters.

In addition to focusing on clinical research, outcomes and education within the division of colorectal surgery, Dr Kiely will lead the incorporation of trans-anal procedures (Ta-TME) for the management of a variety of colorectal conditions at NewYork-Presbyterian/Columbia University Medical Center. He will also be the lead surgeon for the development of the Colorectal Program for NewYork-Presbyterian/Lawrence Hospital in Bronxville, NY offering the robotic approach to surgery for benign and malignant colorectal conditions as well as pelvic floor disorders.
