He had led many research projects which were subsequently published in the various peer reviewed international journals. Most of the concluded research attracted media attention due to its rapid translational effect on public life and policies. He has published extensively and is also the co-author of some modules for the Orthopaedic and Rehabilitation Technology course in the University of Dundee (UK).
