Explore this Laboratory

The Orthopaedic Bioengineering Laboratory was established in 1998. Upon establishing the laboratory at Massachusetts General Hospital, the focus was on the novel application of robotic technology to the in-vitro motion simulation of the human joints. Using this robotic technology, the laboratory pioneered the investigation of human knee function in high flexion angles and revealed many factors that hinder deep flexion after total knee arthroplasty.

In 2003, the Orthopaedic Bioengineering Laboratory established a dual fluoroscopic image system (known currently as DFIS in the literature) that could accurately determine in-vivo six degrees of freedom (6DOF) musculoskeletal joint kinematics. This technique has since contributed to a series of pioneering research papers reporting the in-vivo function of patients with joint replacement implants during functional activities. Many of these works were the first data ever observed in patients with joint replacement implants. The laboratory continues to focus on orthopaedic translational research including developing the next generation of total hip and knee arthroplasty in order to optimize patient outcome.

Research Positions

Post-Doctoral Position at Orthopaedic Bioengineering Lab, Massachusetts General Hospital/Harvard Medical School

The Orthopaedic Bioengineering Lab at Massachusetts General Hospital/Harvard Medical School is looking to recruit an additional Postdoctoral Research Fellow to join our research team. Responsibilities will include quantitative investigation of the in vivo hip and knee biomechanics of patients with total joint replacements. The candidate will process CT and MRI images of patients to construct novel 3D anatomic models of the hip and knee and examine the optimal surgical implantation of joint replacements. This role offers the opportunity to be involved in multiple novel projects enabling the development of a wide range of research experience. Under the supervision of Professor Young-Min Kwon, the candidate will work with a multidisciplinary team of engineers, surgeons, and patients and will develop a strong network with Harvard faculty. The candidate will have the opportunity to present our work nationally and internationally.

Qualified candidates should have a PhD in biomedical, bioengineering, mechanical, or a related engineering discipline and should have graduate research experience with musculoskeletal joint biomechanics. The candidate should have experience in conducting human joint kinematics and kinetics evaluation using imaging and motion analysis techniques. Strong written and oral communication skills are necessary. Proficiency in MATLAB programming is highly desirable.

Interested applicants should submit a CV/resume and contact information for three references (full name, email, and phone). Please submit your application as an email attachment to Jillian Burns at jcburns@mgh.harvard.edu.
