Our Team

Director, USF Diabetes and Endocrinology Center and the USF Health Informatics Institute 

Dr. Krischer is the study chair and director of the Data Coordinating Center for the NIH funded Network for the Identification of Environmental Triggers of Type 1 Diabetes (TEDDY) since its onset in 2004. This epidemiological study has three sites in the United States and three in Europe to study gene-environmental interactions that initiate or promote the development of autoimmunity. Although it does not involve an intervention, it is very similar to TRIGR in that 8000 newborns are enrolled and followed for up to 15 years to investigate gene, environment and gene x environment hypotheses.

In 2009, Dr. Krischer successfully competed to become the Coordinating Center for TrialNet which includes 14 clinical centers, 5 major affiliates and over 150 affiliates in a network accruing to 8 clinical trials in T1D prevention and C-peptide preservation in newly diagnosed subjects. Dr. Krischer is the Chair of the oral insulin prevention trial of multiply positive antibody subjects.

Dr. Krischer has a longstanding commitment to diabetes research and strongly committed to understanding the mechanisms of autoimmunity and disease progression. His office is an international resource to study factors associated with Type 1 Diabetes in that it contains the accumulating databases of the world experience through the DPT-1, TEDDY, TRIGR, and TrialNet databases.
