Andrew T. E. Hartwick

Andrew T. E. Hartwick studies how the eye's light-sensing cells and neural pathways work, including a special class of retinal cells that detect light directly and help regulate functions like pupil responses and circadian (daily) rhythms. More recently, his work has extended to examining how brain injuries, such as concussions in youth hockey players, affect vision and eye-related symptoms. This research combines basic neuroscience of the retina with applied clinical questions about vision after brain trauma.

Publication output has been variable but generally steady over the last decade, with a peak in 2019 and a lower but continued pace (around 1-3 papers per year) in recent years.
