Adjunct Professor
Department of Ophthalmology & Visual Science


Dr. Ordan Lehmann is a professor of Ophthalmology, and Medical Genetics, at the University of Alberta. His clinical interests encompass the management of patients with glaucoma and inherited disease while his research focuses on molecular mechanisms underlying ocular and neurogenetic disorders.

Over the last 15 years, Dr. Lehmann and his laboratory have used pediatric ocular disorders as entry-points for identifying molecular pathways important to a wider range of human disease. One example has been coloboma, where causative genes have been shown to result in a wider range of pediatric disorders, including Lebers Congenital Amaurosis and vertebral fusions. A second is Axenfeld-Rieger Syndrome, and studies of this pediatric glaucoma subtype have identified novel molecular causes of CNS anomalies, corneal vascularisation as well as cerebrovascular disease.

My lab's focus is on the contribution of ciliary dysfunction to a breadth of human disease, particularly neurogenetic disorders. The lab benefits from CIHR funding until 2024, together with support from other agencies, and is recruiting exceptional trainees to accelerate research progress.

We have continuous opportunities for bright, motivated and independent individuals with interests in cell biology, genetics and or neuroscience. Applicants at either the PhD or Post-doctoral level who possess excellent writing and laboratory skills, and wish to work in a cross-disciplinary team, are encouraged to apply by submitting a cover letter outlining their interests together with their CV and 3 references olehmann@ualberta.ca.

Available projects relate to the contribution of ciliary dysfunction to a breadth of pediatric and adult disease, with a particular focus on neurogenetic and ocular disorders. The lab benefits from stable funding, and is actively looking for exceptional trainees to help accelerate research progress.
