Gabriele Saretzki is a cell biologist and visiting lecturer at the Newcastle University Biosciences Institute. She graduated in Genetics from Sankt Petersburg University (Russia) in 1982 and received her PhD in Molecular Biology at the Department of Genetics of Humboldt University of Berlin (Germany) in 1990. She has been involved in ageing and cancer research and has worked on telomeres, telomerase, oxidative stress, DNA damage, and cellular senescence. Since 2001, she has worked at Newcastle University (UK) where she was a lecturer in ageing research from 2002 until 2020, teaching the Biology of Ageing in undergraduate and master's courses. Her particular research interests include the functions of telomerase in cancer and stem cells, as well as the non-canonical functions of the telomerase protein TERT in mitochondria. She has extended this work to the non-canonical functions of TERT in brain and neurons with an interest in neurodegenerative diseases. Dr Saretzki has published more than 105 papers and several book chapters and has an H-index of 51. She is now in early retirement.
