Dr. Kaja is a trained Molecular Biologist and experienced neuroscientist with a long-standing research interest in neurological, neurodegenerative and visual disorders. His expertise lies in the disease areas of migraine, cerebellar ataxia, glaucoma, dry-eye disease, and inflammation.
Following his graduation in Molecular Biology and Biochemistry from the University of Durham (UK), Dr. Kaja completed his doctoral studies in the Neurology department at the Leiden University Medical Center, under the guidance of Prof. Michel Ferrari and Prof. Rune Frants. Subsequently, he followed his interest in calcium signaling and calcium channelopathies and spent two years in the laboratory of Prof. Terrance Snutch at the University of British Columbia in Vancouver, BC. After short stays at the University of North Texas Health Science Center and NeuroSearch A/S, Dr. Kaja moved in 2009 as Research Asssistant Professor to the University of Missouri - Kansas City to continue his research on aspects on calcium signaling in neurological, neurodegenerative and ophthalmic diseases.
In the summer of 2015, Dr. Kaja accepted a position at Loyola University Chicago, Stritch School of Medicine, where he serves as the Dr. John P. and Therese E. Mulcahy Professor in Ophthalmology at the rank of Assistant Professor. Furthermore, Dr. Kaja holds appointments in the Department of Molecular Pharmacology and Therapeutics and at the Edwards Hines Jr. VA Hospital.
Dr. Kaja's laboratory studies the pathophysiology of neurological, neurodegenerative and ophthalmic diseases utilizing a broad experimental approach, ranging from molecular biology to electrophysiology and high resolution imaging.
