Research Area and Interests:

My research examines the effects of acute and chronic exercise on the production of circulating microparticles, a potential novel marker of cardiovascular disease. Microparticles are reported to be elevated in numerous disease states, however, the effects of exercise on the production of microparticles is currently unclear.  Microparticles may play a role in disease prevention and exercise could advance this role.

Another element of my research has examined the role high-intensity interval training plays in improving aerobic fitness in both clinical and sporting populations compared to traditional low volume endurance training.  High-intensity interval training is a time efficient method of improving aerobic fitness in team sports, while maintaining speed and power, leaving more time for technical and tactical development.

I have been involved in research using technologies such as heart rate systems, metabolic systems, GPS, accelerometers, and Dartfish to analyze the physiological demands and movement patterns in Gaelic Games. The results are then used to inform best practice for training.

I have worked in a sport science support role for various individuals, teams and governing bodies including athletics, soccer and Gaelic Games.
