My current research interests are both clinical and basic science. Currently, in the Orthopaedic Research Laboratory, we are investigating the biomechanical properties of the deltoid ligament in the ankle. This is a clinically relevant problem and we will hopefully identify ways to improve the correction of the adult relaxed flat foot. We are also performing a preliminary investigation into the blood supply of the distal tibia to look for a vascularized bone transfer.

We have recently completed a biomechanical study looking at the strength of fixation for proximal metatarsal osteotomies in the correction of hallux valgus and that information has been submitted for publication.

Clinical projects have looked into nerve palsies after total elbow replacement and to reconstructive upper and lower extremity surgery.
