Dr. Guilherme Del Fiol earned his MD from the University of Sao Paulo, Brazil; his MS in Computer Science from the Catholic University of Parana, Brazil; and his PhD in Biomedical Informatics from the University of Utah. He is currently Associate Professor and Vice-Chair of Research in the University of Utah’s Department of Biomedical Informatics. Prior to the University of Utah, Dr. Del Fiol held positions in Clinical Knowledge Management at Intermountain Healthcare and as faculty at the Duke Community and Family Medicine Department. Since 2008, he has served as an elected co-chair of the Clinical Decision Support Work Group at Health Level International (HL7). He is also an elected Fellow of the American College of Medical Informatics (ACMI) and a member of the Comprehensive Cancer Center at Huntsman Cancer Institute.

Dr. Del Fiol's research interests are in the design, development, evaluation, and dissemination of standards-based clinical decision support interventions. He has been focusing particularly in clinical decision support for cancer prevention. He is the lead author of the HL7 Infobutton Standard and the project lead for OpenInfobutton, an open source suite of infobutton tools and Web services, which is in production use at several healthcare organizations throughout the United States, including Intermountain Healthcare, Duke University, and the Veterans Health Administration (VHA). His research has been funded by various sources including the National Library of Medicine (NLM), National Cancer Institute (NCI), AHRQ, CMS, and PCORI.

“Health informatics combines the two areas that appeal to me the most, health care and technology. I feel this combination provides me with greater potential to improve the quality of health care than through direct patient care. It is rewarding knowing that my research work has practical and direct implications in the daily routine of clinicians and ultimately in people’s health. This is a major motivation for me to come to work every day.”
