Dr. Vanderloo’s area of research focuses on the objective measurement of young children’s physical activity levels and sedentary time. Dr. Vanderloo has published some of the first national and international papers examining the variability in young children’s activity levels across various early learning environments as well as exploring approaches for improving objective measurement in this population. Her research interests also extend to knowledge translation and implementation science. Currently, Dr. Vanderloo is working as the Scientific Director at ParticipACTION and recently completed her Research Fellowship at SickKids Hospital in Toronto, where her research examined the association between physical activity and screen use and various health outcomes in young children (namely, mental health, school readiness, and cardiometabolic risk). When she’s not working, Dr. Vanderloo loves spending time outdoors hiking, camping, and playing tennis.
