Overview

Dr. Wren is a biomedical engineer working in clinical environment. As Director of Research for the Children’s Orthopaedic Center at Children’s Hospital Los Angeles, Dr. Wren conducts clinical and basic research in several different areas of orthopaedics. Two of the primary areas are (1) evaluation and treatment of movement abnormalities in children with neurologic deficits and (2) assessment of bone and fractures in children. This research is carried out in collaboration with colleagues in the John C. Wilson, Jr. Motion Analysis Laboratory and the Children’s Imaging Research Program.
