Jan Roelof Polling graduated as an orthoptist from Hogeschool Utrecht in 1998. After his bachelor degree, he worked as a research assistant at Erasmus MC on a randomized study into the effect of the choice of surgery in infantile esotropia. In addition, he was also involved studies in adherence to therapy in the treatment for amblyopia (lazy eye). From 2009, Jan Roelof works at the HU as a lecturer at the full-time bachelor's program in orthoptics and optometry. Because in his clinical work pediatric ophthalmology played an important role, Jan Roelof started his PhD research in 2012 into the development and treatment of progressive myopia in children and hopes to finalizes his PhD in 2019.

For his PhD trajectory, he uses clinical data from treatments at the outpatient clinic of Erasmus MC, but also data from the population based study: Generation R. The Generation R Study is a prospective cohort study from foetal life until young adulthood in a multi-ethnic urban population. The study is designed to identify early environmental and genetic causes of normal and abnormal growth, also covering development of the growing eyes and the influence of the environment.

Jan Roelof Hogeschool became director lecturer of the orthoptics program in 2017 and has the task to integrate research and education and to let the HU clinics play an important role.

In addition to his current clinical work as a senior orthoptist at the Erasmus MC in Rotterdam and his position within the HU, Jan Roelof is active within his international professional association. From 2007-2018 he was representative on behalf of the Netherlands in the International Orthoptic Association and organized a successful international scientific conference in Rotterdam in 2016. In 2018 Jan Roelof was elected President of the International Orthoptic Association and hopes to fulfill this position for 4 years. In addition, Jan Roelof is an active reviewer of scientific papers and literature and is currently editor of the British and Irish Journal of Orthoptics.

Within the position at the HU, Jan Roelof hopes to further study into the influence of children's environment on the development of the eyes and myopia in particular. The question of whether we can have a positive effect on our eye development and to realize a good 'Eye health in the built environment' is one of the research questions that Jan Roelof wants to work on.
