Maria Parker M.D.

  • (503) 494-4687
    • Research Assistant Professor of Ophthalmology School of Medicine
    • Casey Eye Institute School of Medicine


Dr. Parker earned her medical degree with honors in 2004 from Kirov State Medical Academy, Russia. She completed her training in ophthalmology and served as a primary care ophthalmologist in Russia before moving to the United States. She started her research career in 2010 as a post-doctoral fellow at OHSU Casey Eye Institute, where she worked under the supervision of J. Timothy Stout, M.D., and designed and managed pre-clinical trials and projects to develop lentiviral based gene therapy for prevention of corneal rejection and retinal disorders associated with retinal neovascularization. In 2014, as a senior researcher, she joined the Casey Reading Center. She is a certified reader for the reading center, and she has led and contributed to a number of research projects that have furthered understanding of how to utilize ophthalmological testing to assess safety and efficacy in gene therapy trials.

Current research

Dr. Parker's research interests include ophthalmic genetics, gene therapy for retinal and corneal pathologies, ocular imaging, and development and validation of novel parameters for use in clinical trials.
