My main research interests are in injury biomechanics and crash safety and device design, and I have published the only textbook on pedestrian and cyclist impact mechanics together with Dr. Denis Wood. I have also published about 60 papers in international journals on topics varying from head injuries in sport, studies of the mechanics of passive muscle tissue in compression and tension, the influence of vehicle design on human injury, forensic Biomechanics, wound closure devices, studies on the safety of wheelchair users in transportation, the development of roadside safety barriers from natural building materials and the development of walking aids for children with physical disabilities. My principal area of interest lies in human body modeling for crash analysis and in biomechanics and device design for better and safer human interaction with the environment. This began with experimental models of the neck and jaw for my PhD thesis and has progressed to Finite Element and Multi-Body modeling through my work with the Dutch Research Corporation TNO in Delft, The Netherlands and Detroit, USA. The drive now is to create global human body models suitable for virtual crash testing, a field becoming more and more important as the biofidelity of crash test dummies becomes an increasing limitation. In addition, advances in forensic engineering have aided estimation of vehicle speed from crash data (tyre marks, residual crush, pedestrian throw distances). The application of Newtonian mechanics to the statistical data available from police reports allows Monte Carlo simulations to determine the distribution of pedestrian throw distances and energy sharing between vehicles. This was the main thrust of my research while employed with Denis Wood Associates Forensic Engineering Company. In the last 15 years as a researcher at Trinity College Dublin, a major focus has been on characterizing on modeling the mechanical behavior of passive skeletal muscle tissue as this is a crucial tissue in the fields of impact biomechanics, rehabilitation engineering and surgical simulation. My research group has published a number of well cited papers in this field and continues to focus on this topic. In the last three years, I have become active in medical device design. In collaboration with the Northern Ireland-based company moorings Mediquip, I have developed an award-winning Novel walking aid for children with physical disabilities. I also engaged with another company in developing crash resistant swivel seats for easy access to vehicles. I had two PhD students focusing on developing wound closure devices for laparoscopic surgery, with a focus on devices suitable for obese patients. I am collaborated with Dr. Bidisha Ghosh in Civil Engineering in Trinity College Dublin on a project funded by the National Roads Authority of Ireland to develop low-cost roadside barriers from natural building materials. I ma now collaborating with Leinster Rugby and others to study head injuries in rugby.
