Dr. Park is the Director of the Biomaterials Laboratory of the JVL Orthopaedic Research Center located at the Orthopaedic Institute for Children in downtown LA. Dr. Park’s education focused in large part on implant biomaterials and degradation. In the last decade, Dr. Park has conducted extensive studies of metal-on-metal joint replacements, including comprehensive analysis of implant failure, and mechanical, biological, and corrosion analysis. These studies include detailed characterization of implant surface and structural damage to determine mechanisms of wear and failure in total hip and knee replacement components, as well as lumbar and cervical disk replacements.

In the past, Dr. Park has also conducted landmark research studies using animal models to enhance methods for treating fractures, focusing on the effects of weight bearing, electrical muscle stimulation, and lavage of an open fracture, and the effect of pneumatic compression on blood flow to the fracture and healing. Dr. Park developed a novel method for creating different types of closed fractures in animals, and evaluated these using micro CT imaging, in vivo blood flow measurement, histology, and biomechanical testing.
