Maria A. Ciemerych is a developmental and cell biologist focusing on mammalian development, stem cells, and regenerative medicine. She completed her MSc and PhD at the Department of Embryology, Faculty of Biology, University of Warsaw, studying the initial stages and cell cycle regulation during preimplantation mammalian development. She continued to analyse early mouse embryo during her pre- and postdoctoral trainings at Manchester University, Welcome/CRC - University of Cambridge and Jacques Monod Institute - University Paris 7. Finally she moved for 3 years to Dana Farber Cancer Institute – Harvard Medical School, where she was focusing on cell cycle regulation not only in mouse embryos but also in stem cells. After her return to Warsaw, she got involved in the studies on skeletal muscle regeneration and myogenic differentiation of various stem cells, including embryonic stem cells and mesenchymal stem cells. In 2006 she became a head of the Department of Cytology, Faculty of Biology, University of Warsaw. For the last 4 years she has served as a dean for research at the Faculty of Biology, University of Warsaw. Being a scientist, she also actively popularises science during various outreach activities.
