Patrik Danielson is Professor of Anatomy at Umeå University and consultant/attending ophthalmologist at the Centre for Ophthalmology/Ophthalmic surgery at the University Hospital of Umeå. He is the principal investigator of the experimental tendon and cornea research projects at the Department of Integrative Medical Biology.

Professor Danielson's research revolves diseases in collagen rich tissues, with focus on muscle tendons and the cornea of the eye. The aim of this research is to unravel the possible roles of locally produced signal substances, traditionally attributed to neuronal signalling mechanisms, in the development of connective tissue pathology.
This research is performed in collaboration with the University of British Columbia, Vancouver, Canada (Assoc. Prof. Alex Scott), and the Shandong Eye Institute, Qingdao, China (Prof. Qingjun Zhou).
