Prof. Shahragim Tajbakhsh (Stem Cells & Development Lab) obtained a Ph.D. in Biology, Carleton U., Canada on the molecular biology of viruses. Following postdoctoral research at Institut Pasteur, he established an independent group in 2001 called "Stem Cells & Development" to study how stem cells establish and regenerate organs and tissues, with a focus on skeletal muscle. The aim of his laboratory is to investigate stem cell properties during development and postnatally to understand how skeletal muscle is established, and how it regenerates during disease, and after injury. Areas of focus include quiescence, niche, self-renewal, symmetric/asymmetric cell divisions, regeneration, and aging. His lab used mouse genetics to show that muscle stem cell populations are remarkably diverse in function leading to the hypothesis that the modular design in the embryo might in part be responsible for the mosaic response in the pathology of muscles in myopathies.

ST is an EMBO member, former Head of Dept. of Developmental & Stem Cell Biology, and co-director of "Laboratory of Excellence" Consortium, REVIVE (28 labs working on stem cells; 2011-2024). He is a member of different scientific councils (e.g., French myopathy organization, vice-president), several SABs, and presides on editorial boards of 4 scientific journals. He has participated in several EU consortia (FP6, EuroStemCell; FP7, Eurosystem, Optistem, NotchIT) and received several awards including Chair of Excellence Louis Pasteur (Institut Pasteur, 2017) and the French Academy of Sciences. He received numerous competitive grants (e.g., EU, ANR, FRM, ARC, 2-time awardee of ERC Advanced Grant). In 2010, 2015, and 2020 the national HCERES ranked the ST laboratory as A+, outstanding.
