Dr Gregory Tierney


I received my Mechanical Engineering MEng degree in 2014 from the University of Liverpool. I was the recipient of a £1500 annual scholarship for all four years of attendance and received the J.F.Norbury Medal, awarded to the top graduate of the Mechanical Engineering MEng programme. My master’s project was awarded runners up in the international CDIO Academy Cup 2014 (Advanced Projects category). 

In 2014, I was awarded the Irish Research Council’s Government of Ireland Postgraduate Scholarship to complete my PhD in Biomedical Engineering at Trinity College Dublin alongside Leinster Rugby. The aim of the project was to understand how and why concussion injuries were occurring in rugby union. Using a combination of video analysis, motion capture laboratory trials, computational forward dynamic simulations and a novel approach known as model-based image-matching, my research was the first to identify that tackling lower could reduce the risk of concussion for the tackler and the repetitive subconcussive head loading environment for the ball carrier. During my PhD, I published 12 first author peer-reviewed journal articles and co-authored 2 further articles. I received the "Early stage researcher award" at the Bioengineering in Ireland 2015 conference. 

In February 2019, I joined the School of Biomeical Sciences as a lecturer in Biomechanics, teaching on the Sport and Exercise Sciences and Sport and Exercise Medicine programme. 

Research interests

I try to understand how a mechanical blow to the head is translated into biological damage of the brain. This includes both acute concussive impacts and accumulative subconcussive loading. My main research project aims are to develop concussion prevention strategies and law changes for contact sports, objective measures for concussion evaluation and a novel technique to measure 3D head motion directly from live multiple camera view broadcast video footage. This has the potential to reduce the incidence rate of concussion in sport and revolutionise on-field concussion detection and diagnosis methods. My research allows me to work with elite level sports teams and governing bodies. I also work on validating sports wearable technologies such as GPS devices and wearable head sensors.
