Erika Ikeda

Erika completed a Master of Health Science and PhD in Public Health at Auckland University of Technology (AUT) in New Zealand, focusing on physical activity in children and young people. She also trained in Sports Science, specialising in Exercise Physiology, and practiced as a physical education teacher at Juntendo University in Japan.

In June 2019, Erika was appointed Postdoctoral Fellow at the MRC Epidemiology Unit and the Centre for Diet and Activity Research (CEDAR) in University of Cambridge, supervised by Dr Esther van Sluijs. She teaches in the Department of Public Health and Primary Care, and supervises MPhil and PhD students.

Erika is a member of the International Society for Physical Activity and Health, the Society for Social Medicine & Population Health, and the Cambridge Metabolic Network. She reviews manuscripts for several journals including International Journal of Behavioral Nutrition and Physical Activity, Travel Behaviour and Society, and BMC Public Health.

For health benefits, it is recommended that children and young people engage in at least an average of 60 minutes per day of moderate- to vigorous-intensity physical activity across the week. However, the majority of children and young people do not meet this recommendation. Erika’s current research aims to understand how different forms of physical activity such as active travel (e.g., walking, cycling, wheeling), organised sports (i.e., sport organised by a club) and physical education (i.e., game and sport played at school classes) contribute to moderate- to vigorous-intensity physical activity in children and young people. This research can inform and direct government policy and investment into initiatives that effectively increase physical activity in children and young people.

Erika is also involved in the Clean Air Zones project which is a feasibility study of policies and interventions to (i) reduce vehicular traffic around schools and (ii) promote active travel to and from school in children and young people in Cambridgeshire. The project explores the acceptability of the policies and interventions to the schools, parents, local residents and businesses, as well as the potential for unintended consequences and various impacts on different contexts.

Erika also organises external seminar series for the MRC Epidemiology Unit since December 2019 (
