Maya Koronyo-Hamaoui, PhD   |   Research Scientist & Founder

Maya Koronyo-Hamaoui, PhD is Associate Professor in Neurosurgery & Biomedical Sciences at Cedars-Sinai Medical Center.

Dr. Koronyo-Hamaoui has previously been a researcher at the Danek Gertner Institute of Human Genetics at the Sheba Medical Center, Israel. Dr. Koronyo-Hamaoui has published as the first leading author in various important peer-reviewed journals such as Molecular Psychiatry, the Proceedings of the National Academy of Science of the United States of America, the American Journal of Medical Genetics, Neuropsychiatric Genetics, Journal of Psychiatric Research, Journal of Neurochemistry and the European Journal of Neuroscience.

Her research focuses on the genetic basis as well as on the immunological cellular and molecular mechanisms of neurological conditions, including Alzheimer’s disease, anorexia nervosa and amyotrophic lateral sclerosis. Current research developments include the identification and characterization of a retinal pathology specific to Alzheimer’s disease and its in vivo detection via high-resolution optical imaging modality. Future investigation focuses on early diagnosis and disease-modifying therapeutic intervention by understanding the underlying mechanism of repair for Alzheimer’s disease.

Another focus of the laboratory is to study the role that innate and adaptive immune cells play in the repair and regeneration of the central nervous system under chronic neurodegeneration – especially in Alzheimer’s disease. These studies utilize a systemic immune boosting vaccine to elicit local-brain immunoregulation and to help reverse the pathology of Alzheimer’s disease.

She was a member of the International Society of Psychiatric Genetics, and the Israeli Societies for Neuroscience and Biological Psychiatry, and is an active member of the Society of Neuroscience and the Alzheimer’s Association.

Dr. Koronyo-Hamaoui earned her bachelor’s degree cum laude, her master’s magna cum laude and her doctoral research work in the field of psychiatric genetics was obtained from Tel Aviv University. She then completed a fellowship in neuroimmunology at the Weizmann Institute of Science.

Yosef Koronyo, M.Sc., LL.B.   |   Inventor & Founder

Yosef is a research associate in the Department of Neurosurgery at Cedars-Sinai Medical Center working with retinal imaging studies in animal models and human cadaver eyes. He has over 15 years experience in biological research. He has been primarily focused on neuroimmunology, neurodegenerative disorders and optical retinal imaging. His work in neuroimmunology involves the role of innate immune cells and their involvement in pathological conditions in the brain and the retina, specifically in Alzheimer’s disease. He developed unique retinal optical imaging approaches ex-vivo and in-vivo for labeling amyloid-beta plaques with curcumin and examining noninvasively pathological processes and immune cell infiltration in live rodent models. His studies of innate immune cells and astroglia in the retina of MCI and Alzheimer’s patients as well as in rodent models of the disease allows for unique investigation of specific pathology occurring at early stages.
