Dr. Tiziana Cogliati obtained her doctoral degree in Medicinal Chemistry from the University of Milan in Italy and her Ph.D. degree in Cell and Molecular Biology from Leiden University in the Netherlands. She completed her postdoctoral training at the University of Milan, School of Medicine and at the National Cancer Institute, NIH.

From 2003-2008, Dr. Cogliati was a faculty member in the School of Medicine and Biomedical Sciences at Queen’s University Belfast (QUB) in Northern Ireland, UK. In the Center for Vision Science of QUB, she pursued her research interest in retinal neurobiology and development. Her research group studied the cell biology of adult retinal stem cells and the transcriptional regulatory mechanisms which specify cell fate in the retina.

Dr. Cogliati returned to the NIH in 2009 and joined the National Eye Institute. She worked first as a staff scientist with Dr. Anand Swaroop in the Neurobiology, Neurodegeneration & Repair Laboratory where she participated in research on molecular determinants of retinal development, aging and disease, and on the application of stem cells for disease modeling and therapy. She is currently deputy chief of the Ophthalmic Genetics and Visual Function Branch, directed by Dr. Brian Brooks. Dr. Cogliati is involved in research projects aimed at understanding the biology and genetics underlying congenital eye diseases such as coloboma and albinism and in testing therapeutic approaches.
