Ash Kolstad completed his Bachelor of Science (Honours) degree (2019) and Master of Science degree (Specialization: Sport Medicine, 2021) in the Faculty of Kinesiology at the ��ݮ����Ƶ����. He is currently completing a PhD degree (Specialization: Sport Injury Epidemiology) within the Sport Injury Prevention Research Centre at the ��ݮ����Ƶ���� with a focus on personal protective equipment including mouthguards and helmet fit as potential concussion prevention avenues across multiple youth sports. 

In his youth years, Ash sustained multiple concussions from body checking in youth ice hockey which resulted in his inability to continue playing ice hockey and other collision sports, and resulting in his suffering from daily post-concussion symptoms for the past 14 years. It was through suffering these concussions that Ash found a passion for learning more about the different components of concussion and injury prevention  research. Ash started in the Sport Injury Prevention Research Centre in his grade 11 high school year under the supervision of Dr. Carolyn Emery. Ash’s research experience and training includes being an intern at the Patient and Community Engagement Research (PaCER) program to understand the experiences adolescents have while recovering from concussion (supervised by: Dr. Romita Chodhury & Dr. Nancy Marlett), using the KINARM Robotic platform to understand the influence of concussion on sensorimotor function and visuomotor adaption of upper limb movements (supervised by: Dr. Tyler Cluff & Dr. Carolyn Emery), and examining symptom and performance validity testing in youth suffering mild traumatic brain injury (supervised by: Dr. Keith Yeates). Ash's undergraduate honours project assessed if a relationship existed between baseline psychosocial (e.g., anxiety) and physiological (e.g., headache) factors for predicting time to recovery in youth suffering concussion (supervised by: Dr. Keith Yeates & Dr. Kathryn Schneider). Through his MSc research, Ash examined mouthguard use and the risk of concussion in youth ice hockey players, which showed a 28% lower rate of concussion when a mouthguard was worn (both dentist-fit and store bought types showed consistent protection), which he hopes will inform policy to mandate mouthguard use across youth ice hockey leagues internationally.

As a current PhD Candidate within the Sport Injury Prevention Research Centre (Supervisors: Dr. Carolyn Emery & Dr. Brent Hagel), Ash has been a student-mentor for over 10 students in completing their undergraduate, MSc, and PhD work across different areas of injury prevention and video analysis methods with a leading or contributing author to 15 peer-reviewed manuscripts. He is continuing his own evaluation of personal protective equipment for the prevention of concussion across multiple collision-based sports, including evaluation of coach helmet fit training practices on the risk of concussion in youth tackle football. Ash’s PhD work is part of the SHRed Concussions pan-Canadian longitudinal research study (supported by the NFL Play Smart, Play Safe grant) and he receives funding (and is grateful for this funding) for his PhD work from the Izaak Walton Killam Memorial Scholarship, CIHR Frederick Banting and Charles Best Doctoral Award, and the ��ݮ����Ƶ���� Eyes High Doctoral Recruitment Scholarship. Ash strongly believes that injury prevention starts with partnerships with research institutions and sport organizations to co-lead strategies to maximize benefits to the sport and promote player safety.
