Haico van Attikum received his PhD in Molecular Genetics from the Leiden University in 2003. During his PhD research he studied how DNA repair pathways integrate foreign DNA into the genome of yeast and plant cells (group of Prof. Paul Hooykaas). He became a postdoctoral fellow in the group of Prof. Susan Gasser at the University of Geneva (Switzerland) in 2003 and accompanied the group when it moved to the Friedrich Miescher Institute in Basel (Switzerland) in 2004. His postdoctoral research focused on elucidating the role of chromatin remodeling during DNA damage repair in yeast, for which he received long-term fellowships from the European Molecular Biology Organization (EMBO) and Human Frontier Science Program (HFSP). In the summer of 2007 he moved back to the Netherlands, where he was appointed as junior group leader at the Department of Toxicogenetics of the Leiden University Medical Center, and currently holds a position as Associate professor at the Department of Human Genetics. His group employs a cross-disciplinary systems biology-based approach that encompasses genetics, proteomics, microscopy and bioinformatics in yeast, mouse and human/patient cells to identify the proteins that constitute DNA damage response pathways, and study their impact on genome stability maintenance and human disease. For his work he receives funding from different agencies, including the Netherlands Organization for Scientific Research (NWO-VIDI, TOP-GO), Human Frontier Science Program (HFSP-CDA), Dutch Cancer Society (KWF) and the European Research Council (ERC-Consolidator). For his achievements so far he was awarded the Young Scientist Award 2009 by the European Environmental Mutagens Society (EEMS) and C.J. Kok price by the Leiden University Medical Center (2012). He is regularly invited as a speaker at (inter)national conferences and serving as a member of (inter)national granting committees and reviewer for peer-reviewed scientific journals.
