Thomas Santarius, MD PhD FRCS(SN) is a Consultant Neurosurgeon at Cambridge University Hospitals, UK. His clinical and teaching efforts are focused on perfecting surgical techniques as well as research into the biology of brain tumours in adults and children.

Thomas Santarius grew up Czechoslovakia and there, at Universitas Palackiensis in Olomouc, he obtained his medical degree (MD). He received his neurosurgical training at the Cambridge University Hospitals, UK where he is now a Consultant Neurosurgeon.

His research focuses on fundamental biology of cancer and molecular genetics of brain tumours. He was trained at Harvard University in Boston, USA and the Sanger Institute (PhD in Natural Sciences, University of Cambridge). He described aspects of genomic amplifications at DNA sequence level, classified genomic amplifications in human cancer, described a novel human amplified cancer gene GLO1 and contributed to recent discovery of novel meningioma genes.

He also co-founded Cambridge Lectures in Neurosurgical Anatomy. This course uses 3D images and videos of cadaveric dissections and as well as neurosurgical operations to promote perfection of surgical techniques through in-depth understanding of surgical anatomy. Mr Santarius serves as a faculty on a number of national and international neurosurgical courses focused on anatomy and neurosurgical techniques.

Mr Santarius' clinical practise focuses on surgical treatment of brain tumours in children and adults, including those affecting brainstem, cerebellum, ventricular and periventricular tumours, sellar, parasellar and pineal region tumours. He has expertise in glioma surgery utilising intraoperative electrophysiological mapping and monitoring (cortical and subcortical mapping and monitoring) in awake and anaesthetised patients.
