Eligible to supervise Masters and PhD - email supervisor to discuss availability.

I work in the field of biomechanics (the application of mechanics to understand biological phenomena), specifically orthopaedic (our bones, muscles, tendons and ligaments) biomechanics. I am a NHMRC R.D Wright Fellow (2017-2021). I am recognised as an emerging leader in the field with awards from the International Society of Biomechanics (footwear biomechanics group), International Foot and Ankle Biomechanics community, Australian and New Zealand Orthopaedic Research Society, and the ORS (USA). I am the immediate Past-President of the Australian and New Zealand Orthopaedic Research Society, and editorial board member for the Journal of Biomechanics and Gait and Posture.

I have made significant contributions in to our understanding of how mechanical loading can influence the out come of complex orthopaedic surgeries (e.g. fracture repair, knee replacement and hip replacement) using a novel combination of experimental and computational methods to model the human musculoskeletal system.

Research experience and track record

My primary research focus is the biomechanics of orthopaedic disease and injury. This includes articular fracture management, which is known to be associated with osteoarthritis onset, and joint arthroplasty – the end point for most people with degenerative joint disease. I use an exciting combination of biomechanical modelling methods, medial imaging, physical activity monitoring and patient reported outcome measures to explore these conditions. I have a secondary interest in movement disorders and the neurological control of movement.

I have the following projects available for new students in 2021-2022.

 
Title Description Level Start Special Reqs.
Using machine learning models for gait analysis Our goal is to take the next technology leap in gait analysis. We aim to use pose estimation machine learning models to predict human motion and integrate these data with industry standard biomechanical modelling software. HDR Semester 1 and 2 None
Understanding the importance of variations of tip-apex distance following surgical repair of neck of femur fracture Neck of femur fracture is typically treated surgically with an intramedullary nail. The final position or change in position of the tip of the device in the femoral head is often used as a measure of surgical success. However, this is typically considered in 2D and therefore fails to account for the possible 3D variations that can result in similar 2D positions. This project will model the possible variations in position and explore how these are associated with clinical outcomes Honours and HDR Semester 1 and 2 None
Pilot RCT for weight bearing after tibial plateau fractur We have established strong data to show that immediate weight bearing as tolerated by pain after surgical repair of tibial plateau fracture is safe. We are now looking to establish if there is evidence for better patient reported and clinical outcomes through a pilot RCT. We will use outcomes measures such as gait analysis and radiostereometric analysis. HDR Semester 1 and 2 None
24-hour activity patterns after hip replacement through the private system We have previously published unique data showing no change in 24-hour activity patterns following hip replacement surgery through the public system. This project will use the same approach (wearable sensors) to quantify 24-hour activity patterns in a  similar group of patients from the private system. HDR Semester 1 and 2 None
The relationship between articular shape and biomechanics in the arthritic hip The project develop statistical shape models of arthritis hip from medical imaging (CT and MRI) and investigate how the modes of variation in shape relate to the biomechanics of the hip during walking.  HDR Semester 1 and 2 None
Real-time force-feedback for monitoring weight bearing after orthopaedic surgery  The RAH has recently acquired a novel treadmill with force sensors mounted under the main belt. The long term goal of this device is to guide clinical decision making through large labelled datasets. In the first instance we will develop push-button programs and establish their reliability and validity in an orthopaedic outpatient setting.  Honours and HDR Semester 1 and 2 None
Model predictive control for simulating the outcome of orthopaedic surgery The goal of this work is to predict the functional (biomechanical) outcome of surgery where the goal is to change geometry, e.g. moving the hip joint centre medially in hip replacement. We will use model predictive control for these simulations and validate against a large dataset of already captured outcomes with known changes in geometry.  HDR Semester 1 and 2 None
