Katie Hixon

Assistant Professor of Engineering

Clinical Assistant Professor of Orthopaedics


Professor Hixon's research focuses on tissue engineering/regenerative medicine strategies to improve treatment and facilitate healing in patients with congenital and traumatic craniofacial anomalies, as well as those with delayed or failed musculoskeletal healing. Prior to joining the Dartmouth faculty, Hixon earned a PhD in biomedical engineering at Saint Louis University. Her research broadly included tissue engineering scaffold fabrication for the treatment of critical-size defects and craniofacial/maxillofacial congenital conditions. Following this, she completed a postdoctoral position in the Department of Orthopaedic Surgery at Washington University in St. Louis School of Medicine. Here she was awarded the NIH F32 Ruth L. Kirschstein National Research Service Award to study bone healing following fracture and develop a clinically relevant animal model to test therapeutic interventions. Hixon's work will continue to contribute cutting-edge research utilizing orthopaedic and craniofacial models to drive the development of novel tissue engineering/regenerative medicine therapies, impacting dental, oral, craniofacial, and musculoskeletal health.
