Dr. Chachoua obtained his Bachelor degree in biochemistry at Setif University (Algeria) in 2008, and Master’s degree at Taurida National University (Ukraine) in 2010. Between 2012 and 2017, he joined the lab of Professor Stefan Constantinescu at de Duve institute and Ludwig institute for cancer research (University Catholique de Louvain, Brussels, Belgium), where he obtained his PhD and discovered new mechanisms for STAT5 activation in myeloproliferative neoplasms (MPNs) and secondary acute myeloid leukemia (sAML). Subsequently, he worked as a postdoctoral fellow in the labs of Professors Rolf Ohlsson and Anita Gondor at Karolinska Institute (Stockholm, Sweden), where he studied the interplay between three dimensional chromatin organisation and gene expression. His postdoc work led to the discovery of the gene gating in mammalian cancer cells. Currently, he is an assistant professor at MBG department in Bilkent University, and the main focus of his lab is to study 3D chromatin organization in MPNs and sAML.
