Thomas Helleday – CSO

Thomas has >15 years experience as full professor, researching DNA damage response (DDR) and DNA repair at University of Oxford, Univ of Sheffield, Stockholm University and now Karolinska Institutet. He currently heads a large multidisciplinary translational research group at SciLifeLab, Helleday Laboratory, focusing on understanding DDR biology and translating the findings into novel anti-cancer treatments concepts and drugs. The group was first to demonstrate the synthetic lethality concept for treating cancer by showing homologous recombination defective cancers (e.g., BRCA) were sensitive to PARP inhibitors. Professor Helleday has been awarded numerous eminent international grants and awards in recognition of his research accomplishments including the Eppendorf-Nature Young European Investigator Award (2005) and ERC advanced grants (2010 and 2016).
