Current Research:
Dr. Zemek’s research is focused on pediatric concussion and prognosticators of post-concussive syndrome following pediatric minor traumatic head injury. He is the principal investigator on multiple federal peer-reviewed grants, with expertise in pediatric concussion. He is the principal investigator for the Predicting Persistent Post-concussion Problems in Pediatrics (5P) study, the largest concussion study to-date. He is also the principal investigator for the randomized-controlled trial PedCARE (Pediatric Concussion Assessment of Rest and Exertion) to determine the optimal balance of physical activity vs. rest in children following concussion.

Biography:
Dr. Zemek is a pediatric emergency researcher with experience in multicenter studies, randomized controlled trials, and systematic reviews. He has research experience in pediatric concussion, including systematic reviews, guideline development, health administrative datasets, derivation and validation of clinical prediction rules, and interventional trials. Dr. Zemek is leading a national research program on pediatric concussion, through which he conducted the largest concussion study in the world to-date examining the predictors for Persistent Post-Concussion Symptoms in children suffering a concussion (5P study). He also led an international team for the development of guidelines for the management of pediatric concussion. Through Pediatric Emergency Research Canada (PERC), Dr. Zemek is also an investigator on multiple asthma studies and mental health studies of children presenting to the Emergency Department.
Achievements:
Recipient of the Dr. Jane Gillett Research Award, from the Brain Injury Association of Canada, "granted to an individual or organization for their outstanding contribution to advance the cause of acquired brain injury in Canada". He also received the Terry Klassen Young Investigator Award. This national award, presented annually at the national Pediatric Emergency Research Canada (PERC) meeting, is given to the young researcher whose research is novel, original and of the highest caliber and who embodies the spirit of interpersonal and interdisciplinary collaboration as envisioned by Dr. Terry Klassen and PERC.

He also led an international team of experts to create the world's first comprehensive pediatric concussion guidelines.
