Tiziana Cogliati holds a doctoral degree in Medicinal Chemistry from the University of Milan in Italy and a Ph.D. degree in Cell and Molecular Biology from Leiden University in the Netherlands. Dr. Cogliati completed her postdoctoral training at the University of Milan and at the National Cancer Institute, here at the NIH. She subsequently became a faculty member in the Center for Vision Science at Queen’s University Belfast in Northern Ireland. Her research group studied the biology of adult retinal stem cells and the transcriptional regulatory networks which specify cell fate in the retina. Dr. Cogliati joined the National Eye Institute in 2009 as a Staff Scientist 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. Later, she became the Deputy Branch Chief of the Ophthalmic Genetics and Visual Function Branch directed by Dr. Brian Brooks and was involved in research projects on the biology and genetics of congenital eye diseases such as coloboma and albinism. She joined the Division of Aging Biology as a program officer in the Biological Resources Branch at NIA in December of 2021.

Research Interests/Portfolio

Lifespan Interventions Program

  • Mechanisms of action and efficacy of interventions that extend lifespan, with an emphasis on uncovering shared versus exclusive molecular mechanisms (by intervention and by tissue type).
  • Impact of husbandry on rates of aging and health outcomes in laboratory animals subject to lifespan-altering interventions (focused on laboratory rodents commonly used in biological research).
