Based in Stony Brook, New York, Dr. Elliott Bennett-Guerrero joined Stony Brook Medicine as a tenured professor of anesthesiology and vice chair for clinical research and innovation in the anesthesiology department in 2015.

Dr. Elliott Bennett-Guerrero's research interests include quality improvement, postoperative morbidity, surgical site infection, and the safety and effectiveness of blood transfusions. He also has an interest in the potential impact of anesthetic technique on outcomes after major cancer surgery. He led a large randomized clinical trial (GA-CARES trial), which was recently published in ANESTHESIOLOGY, the official journal of the American Society of Anesthesiologists (ASA). This trial, which enrolled over 1800 patients at 5 medical centers in New York State, found that use of propofol to maintain general anesthesia did not result in better long term survival after major cancer surgery compared with use of volatile (gas) anesthesia. Dr. Bennett-Guerrero is interviewed about this landmark trial in "Featured Author Podcast: Anesthesia Type in Cancer Surgery" produced by the ASA on December 17, 2025.

Dr. Bennett-Guerrero earned his medical degree from Harvard Medical School, followed by an anesthesiology residency and a critical care medicine fellowship at Duke University. He spent 12 years on the Duke University faculty, as a tenured professor, working clinically in the Operating Room and the Intensive Care Unit (ICU) and also as the director of perioperative clinical research with the Duke Clinical Research Institute. In addition to his medical interests, Dr. Elliott Bennett-Guerrero has completed multiple half-ironman triathlons.
