Ian M. MacDonald MSc MD CM is a Professor in the Department of Ophthalmology and Visual Sciences, University of Alberta and recently stepped down after four terms as its Chair. From 2007-2008, he served as Branch Chief of Ophthalmic Genetics at the National Eye Institute of the NIH in Bethesda, MD. A McGill graduate in Medicine, Dr. MacDonald completed Ophthalmology residency training at the University of Ottawa and Clinical Genetics fellowship training at the University of Ottawa, Queen’s University, Kingston and the Hospital for Sick Children, Toronto. He was a Career Scientist of the Ontario Ministry of Health at the University of Ottawa prior to moving to Edmonton in 1992.
His main research interest is inherited retinal disorders, in particular, maculopathies and choroideremia. In 2009, in recognition of his work in Canada to foster the development of academic ophthalmology, he was elected to as a Fellow of the Canadian Academy of Health Sciences.

Matthew Benson MD is a graduate student and resident in the Department of Ophthalmology and Visual Sciences and he is completing a Master of Science degree in the MacDonald lab. He received his Medical Degree from the University of Alberta in 2015.
Matthew is particularly interested in inherited retinal dystrophies and he is currently investigating the mechanism of disease in a patient with a peroxisomal biogenesis disorder. He is the 2018 recipient of the Foundation Fighting Blindness Canada Clinician-Scientist Emerging Leader Award.
Geoff Casey BSc (EE), BSc (Mol Gen) is currently completing a Master of Science degree in Medical Genetics in the MacDonald lab. He has received Bachelor of Science degrees in Electrical Engineering/Nanotechnology and Molecular Biology from the University of Alberta.
Geoff is contributing to the development of novel viral vectors for the treatment of genetic ocular disorders. He is performing preclinical characterizations of viral vectors and evaluating novel methods of mitigating immune responses against these vectors.
Lance Doucette PhD is a Research Associate in the Department of Ophthalmology and Visual Sciences, University of Alberta under the supervision of Dr. Ian M. MacDonald since April of 2017. He completed his PhD in Human Genetics at Memorial University in 2012 where he studied the genetic cause of inherited blindness in the Newfoundland population.
In 2013, he moved to the University of Alberta as a Postdoctoral Fellow in the Department of Medical Genetics under the supervision of Dr. Michael Walter where he studied the role of a developmental gene, FOXC1 and its role in the molecular biology of glaucoma.
In Dr. MacDonald’s Laboratory, Dr. Doucette’s interest is understanding the genetics and molecular biology behind inherited ocular disorders, particularly macular and retinal dystrophies. His expertise is in identifying disease genes through next generation sequencing, and using molecular biology techniques to understand how these genes are involved in eye disease.

Manlong Xu MD PhD is a clinical research fellow in the Department of Ophthalmology and Visual Sciences at the University of Alberta under the supervision of Dr. Ian M. MacDonald since December 2015. She completed her PhD in Vision Science and Biology (joint degree) at University of Waterloo in 2015, where she studied the individual and combined toxicity of UV radiation and chemicals on the eye.
Previously, Dr. Xu was a physician specialized in internal medicine (with special training in rheumatology) in China, where she did clinical studies on ankylosing spondylitis and systemic lupus erythematosus (SLE).
In Dr. MacDonald’s laboratory, Dr. Xu engages in clinical research on the natural history and gene therapy for retinal degeneration (especially choroideremia). Her research interest is visual field progression in inherited eye disorders.
