Department of Biomechanics

Christina Esposito, PhD

Dr. Esposito joined the Center for Biomechanical Engineering as a postdoctoral fellow in 2013 after completing her doctoral studies at the University of New South Wales in Sydney, Australia.  She specializes in implant retrieval analysis of joint replacements and periprosthetic tissue reactions to wear debris.  Prior to HSS, she focused on the mechanisms and implications of wear in ceramic-on-ceramic and metal-on-metal hip replacements.   Currently, she continues to do implant retrieval research, with the long term goals of understanding how devices function and developing better devices to improve patient outcomes.  She is learning more about orthopaedic biomechanics, under the supervision of Dr. Timothy Wright, and is working with surgeons to develop patient specific plans for hip component placement, using new imaging and navigation technologies.
