In 2008 I was fortunate enough to be invited to be part of a research team on a large population based project focusing on the incidence and outcome of traumatic brain injury (TBI) in New Zealand (led by Professor Valery Feigin National Institute of Stroke and Applied Neurosciences, AUT University). At the time I knew little about TBI or population based research, but the last five years have changed that. My involvement in the project has led to on-going collaborations and friendships, and continues to provide me with on-going challenges as a researcher. More importantly, however, thanks to those who participated in our research, it has given me an enormous appreciation of the daily challenges faced by those affected by TBI and the desire to do research that ultimately will make a difference for them and other TBI survivors.
