Professional Biography

Dr. Michael Haller is a pediatric endocrinologist with a passion for patient care, teaching, and research. Dr. Haller’s research focuses on predicting, preventing, and reversing type 1 diabetes through a team approach that emphasizes translating findings from the laboratory bench to the patient’s bedside in a timely manner. Dr. Haller is an active investigator in the NIH funded Type 1 Diabetes TrialNet and The Environmental Determinants of Diabetes in Youth (TEDDY) study. Dr. Haller currently serves as the Principal Investigator (PI) for the TrialNet ATG/GCSF study funded collaboratively by the NIH, the Helmsley Trust, and Sanofi. He also serves as a co-investigator for all other TrialNet studies at the University of Florida, and as the Chair of the Clinical Implementation Committee for the international TEDDY study. Dr. Haller also helps to direct the University of Florida Type 1 Diabetes Extension for Community Healthcare Outcomes (ECHO) program. This program, funded by The Helmsley Charitable Trust, uses tele-education to provide primary care providers with improved skills to manage their type 1 diabetes patients who lack access to subspecialty care.

In 2008, Dr. Haller, and his colleagues Dr. Desmond Schatz and Dr. Mark Atkinson received the JDRF’s highest award, the Mary Tyler Moore and S.Robert Levine Excellence in Clinical Research Award, for their team approach to developing therapies for type 1 diabetes. In 2009, Dr. Haller and his colleagues received the ADA Cure Award and in 2010 Dr. Haller received the ISPAD Young Investigator Award. In 2016, Dr. Haller took over as the Division Chief from his longtime mentor and friend, Dr. Janet Silverstein. In 2017, Dr. Haller received the prestigious University of Florida Research Professorship.
