Grégoire Stik obtained a MSc degree in Cellular and Molecular Biology at the University of Tours (France) in 2008. He started to be interested in the mechanisms of gene regulation in disease and obtained a PhD in Life Sciences in 2012 at the University of Tours (France). His works showed how oncogenic herpesvirus uses cellular transcription factors to express microRNAs essential to induce lymphoma (Stik et al., 2010 RNA; Stik et al., 2013 Journal of Virology). He moved then to the Developmental Biology Laboratory in Paris (CNRS, UMR7622, Paris) as a postdoctoral fellow where he focused on studying the mechanisms controlling the hematopoietic stem cell fate (Stik et al., 2017 Journal of Cell Biology). In fall 2016, he joined the Centre for Genomic Regulatin in Barcelona. As a Marie Skłodowska-Curie fellow first and then as Staff Scientist, he started to create the ground for an independent career and developed new research lines to explore the role of 3D genome organization on gene regulation during differentiation, oncogenesis and inflammation (Stik et al., 2020 Nature Genetics, co-corresponding; Soochit et al., 2021 Nature Cell Biology, Cuartero et al., 2022, Nature Reviews Immunology). In 2022, he started as Junior Group Leader of the “Nuclear Architecture in Leukemia” laboratory at the Josep Carreras Leukaemia Research Institute.
