  • Verawan studied Molecular Biology at University of Lyon, France. In 2009, she started her PhD work in Prof. Thomas Braun’s group at the Max-Planck-Institute of Heart and Lung Research in Bad Nauheim, Germany. Her project focused on epigenetic mechanisms regulating the quiescent state of muscle stem cells and chromatin-base mechanisms contributing to the distinct stem cell states. After obtaining her PhD at the end of 2013, she continued as a post-doctoral researcher in the same lab. In 2014, she joined the group of Prof. Reinhard Fässler at the Max-Planck-Institute for Biochemistry in Martinsried and further investigated the role of integrin-adhesome on mesenchymal tumor stem cell homing. In March 2017, she joined the Greten lab where her research focuses on the function of chromatin in driving aberrant transcription programs during metastasis of colon cancer.
