My main research interests lie in medical image processing and understanding. In particular, I am interested in examining the shape of the femur and the trabecular structure on radiographs and DXA scans and seeing how they relate to bone disorders such as Osteoporosis and Osteoarthritis.

More details can be found through the research pages on this site.
