Egan's research interests revolve around clinical pharmacology investigative methods applied to the development and understanding of novel intravenous anesthetics and opioids, optimal anesthetic drug administration regimens, and anesthetic drug interactions.[2][3]
Egan served as a board member, treasurer, and president of the International Society for Anaesthetic Pharmacology for many years.[4]
In 1978, Egan graduated from Olympus High School in Salt Lake City. Subsequently, he enrolled at Brigham Young University and completed his undergraduate studies in the humanities. He attended medical school at the University of Utah School of Medicine, graduating in 1986. After completing a preliminary residency in general surgery at the University of Utah in 1988, he pursued postgraduate training in anesthesiology, which he began at the University of Utah and completed at Stanford University in 1991. Following residency, he also completed a fellowship in clinical pharmacology at Stanford. Egan took sabbatical as a visiting scientist at the Imperial College in London, UK in 2000, studying the effects of dexmedotomidine using functional magnetic resonance techniques.[1]
Egan started his academic career as a clinical instructor and assistant professor for the department of anesthesiology at Stanford University. He relocated to the University of Utah as an assistant professor in 1993, eventually becoming professor. Since 2004, he has been a professor of anesthesiology, with adjunct positions in the departments of pharmaceutics, bioengineering, and neurosurgery. Egan served as president of the medical staff and chair of the medical board at the University of Utah Health Sciences Center from 2006 to 2008.[5]
Egan has been the chair of the department of anesthesiology since 2015, and is the holder of the K.C. Wong Presidential Endowed Chair in the department of anesthesiology at the University of Utah since 2004.[6]
His clinical practice is focused primarily on neuroanesthesia; he served as the chief of neuroanesthesia at the University of Utah for over 10 years.[5]
Egan is the principal creator of Safe Sedation Training (SST), a virtual preceptorship for training non-anesthesia professionals in procedural sedation.[7] He is a founding owner of a medical education and consulting company called Medvis.[8]
Egan served as an associate editor of the scientific journal Anesthesiology from 1999 to 2005 and has served as associate editor of the British Journal of Anaesthesia since 2013.[9]
Egan has authored over 150 publications.[2][10] A significant part of Egan's work has been focused on drug interactions and computer controlled drug delivery systems. He has worked on developing various methods of total intravenous anesthesia (TIVA),[11] has demonstrated the clinical use of the short acting opioid remifentanil,[12] and defined interactions between intravenous anesthetics i.e., propofol and opioids.[13] Much of his research focuses on the pharmacological and therapeutic principles of sedatives and analgesic drugs.[14]
Talmage married Julie Cook in 1984. They have five children. He is a member of the Church of Jesus Christ of Latter-day Saints (LDS) and served as a volunteer missionary in Sendai, Japan, from 1979 to 1981.[15] He later served as a lay pastor (bishop) of a University of Utah LDS student congregation from 2011 to 2014.[16]
