Dr. Imel’s clinical and research focus is on bone and mineral disorders, especially rare bone disorders, including X-linked hypophosphatemia (XLH), other hypophosphatemic disorders and rare metabolic bone disorders. His unique background includes dual training and certification in both Adult Endocrinology and Pediatric Endocrinology at Indiana University School of Medicine and Riley Hospital for Children. Dr. Imel is also an Affiliate Scientist of the Regenstrief Institute’s Center for Biomedical Informatics, and Core Director for the Musculoskeletal Informatics Methodology Core of the Indiana Center for Musculoskeletal Health-Clinical Research Core, conducting health informatics studies of clinical musculoskeletal outcomes. He conducts clinical and translational research in both rare and common musculoskeletal diseases, including clinical trials in X-linked hypophosphatemia (XLH), autosomal dominant hypophosphatemic rickets (ADHR), autosomal dominant osteopetrosis (ADO2), as well as osteoporosis, and studies of musculoskeletal complications of chronic conditions.  Dr. Imel also conducts research in congenital adrenal hyperplasia and musculoskeletal complications of cystic fibrosis.

His clinical practice includes care of adult and pediatric patients with metabolic bone disorders, including a large population of children and adults with XLH. He also sees young adult patients that have transitioned from pediatric to adult care with conditions such as Turner syndrome and classic congenital adrenal hyperplasia.
