For individuals who know that they want to obtain the training that would best prepare them for a career in academic endocrinology, the University of Colorado can provide a 3 year research intensive training experience supported by our institutional training grant. For fellows who select a research track, 75% of the time during the second and 3rd years of training is primarily focused on research with some continued clinical training. A majority of the trainee's time is spent in a mentored research experience. One half day per week is spent in his/her continuity clinic, and two half days per month are devoted to specialized training in lipid disorders, pediatric endocrinology, high risk obstetrics, reproductive endocrine and osteoporosis/metabolic bone clinics. Basic and clinical research experiences in a wide range of fields relevant to endocrinology are available. The world renowned Barbara Davis Center has a number of investigators who study the immunopathogensis of type 1 diabetes as well as innovative therapies for this condition. The Anschutz Health and Wellness Center and associated NIH funded Nutrition Obesity Research Center has more than 100 researchers studying obesity and related metabolic disorders from the molecular/cellular level all the way to the public health interventions. The Hormones and Cancer group has a number of investigators studying relationships between hormone signaling and breast and thyroid cancer to name just a few. Fellows will learn about potential research opportunities during their first year of training and select a lab/mentor to begin the research focused period of training in July of their second year. Fellows will have the opportunity to present their work at national meetings and many have succeeded in obtaining training awards to continue their development into independent scientists.
