Lars Hanssen is a Clinical Lecturer in Haematology at Imperial College London, with a clinical interest in paediatric haematology. He completed his DPhil at the University of Oxford in the laboratory of Professor Doug Higgs FRS, where his research focused on the regulation of the α-globin locus and the role of chromatin architecture in regulating tissue-specific gene expression during erythropoiesis. He is currently based in the group of Dr Deena Iskander at Imperial College London, where his work centres on the molecular basis underlying the erythropoietic defects observed in Diamond-Blackfan Anaemia Syndrome.​​​​​​​​​​​​​​​​
