biography

Ran Brosh earned his BSc from the Tel Aviv University and his MSc and PhD from the Weizmann Institute of Science (Rehovot, Israel). During this time his research focused on the molecular biology of the p53 tumor suppressor and its roles in cancer, development and somatic cell reprogramming. For his postdoctoral training, Ran joined the lab of Dr. Ihor R. Lemischka at the Black Family Stem Cell Institute in the Icahn School of Medicine at Mount Sinai (New York, USA). During his postdoctoral training Ran has gained expertise and knowledge in the fields of Stem Cells, Regeneration and Development and has developed a unique and novel molecular methodology to study protein function in mammalian stem cells.
