Dr. Pories research interests have been in nutrition, pediatric and bariatric surgery. His research interests included the first report that zinc is not only an essential element for plants but also animals. He described the role of the element in wound healing, development and the growth of cancers. During these studies he participated in the fortification of animal feeds as well as the addition of trace elements to parenteral and alimentary formulations. This discovery, made as a second year medical student, was a part of the green revolution. The addition of two cents worth of Zn, added to a ton of feed, accelerated poultry egg laying by 45 days, finished broilers in six weeks instead of ten and increased feed efficiency in swine by 20%.
On graduation from medical school, he joined the USAF for twelve years of service, rendering primary care and obstetrics in France and serving as a part-time fellow in head and neck surger at the University of Nancy. Following his internship, he returned to the University of Rochester to complete is surgical training and serve a year as a biochemist in the Manhattan Project. Following his residency and certification in general and cardio-thoracic surgery, he was named Chief of Surgery at Wright Patterson AFB for five years of the Vietnam War. In 1967, after 12 years as a career military officer, he returned to Rochester as Asst. Professor in an active practice of vascular as well as head and neck cancer surgery.

In 1980, he developed the current version of the gastric bypass and was the first to document that the operation produced durable weight loss and the full remission of type 2 diabetes in 83%, even after 9.2 years with a reduction of mortality by 735. To improve the national outcomes from bariatric surgery, he founded the Surgical Review Corporation that developed the international Bariatric Surgery Centers of Excellence Program as well as developing the BOLD database that led to a reduction of the 90 day mortality in the US from about 10% to 0.3%. He was also the first to develop a postgraduate curriculum for graduate surgical education, published through four editions.
His current research interest is the molecular explanation why type 2 diabetes clears within a matter of days following bariatric surgery His group has had uninterrupted funding from the NIH for over three decades.
