Orthopaedic research in my laboratory is focused on developing cartilage and bone regenerative techniques with tissue engineering approaches using synthetic scaffolds and adult stem cells extracted from fat tissue. The range of research projects related to this work includes biomaterials studies to develop a variety of scaffolds prepared on a 3D printing system from microCT images of bone tissue, biomechanics studies to evaluate strength and stiffness characteristics of implantable scaffolds, computer based finite element modeling of scaffolds and tissues, software development for implantable transmitters, physiological test development to test scaffolds under physiological loading conditions, cell studies involving development of extraction, sorting , conversion and cell alignment techniques.
The overall goal of all these projects is development of clinically viable tissue engineering techniques that include monitoring of healing using sensors and implantable transmitters.
My involvement in the Orthopaedic residency program includes instructing residents in orthopedic biomaterials and biomechanics, providing laboratory support for students and surgical faculty to carry out bench top research projects, participating in radiology teaching conference to provide biomaterials and biomechanics expertise applied to surgical procedures. Student opportunities include learning about implant development and design, biomaterials and biomechanics research in orthopedics as well as tissue engineering strategies to regenerate bone and cartilage.
