Dr Nikolaos Dikaios

PhD

Introduction

Nikolaos Dikaios joined Surrey in 2016, prior to his appointment at Surrey he was a Research Associate in the Medical Physics department at University College London. Dr Dikaios received his PhD (2011) in Medical Physics from the University of Cambridge, Wolfson Brain Imaging Centre. Before his PhD he obtained a degree in Physics (concentration in Nuclear and Particle physics) from the University of Athens in 2004, and in 2007 he completed a Postgraduate program on Biomedical Technology at the Dpt of Electrical Engineering, National Technical University of Athens, Greece. During the postgraduate program he was also employed on secondment to the UK as a physicist at Hammersmith Imanet Ltd part of GE Healthcare Biosciences.

He has published 26 peer-reviewed papers, 23 of which have a top-quartile impact factor (THOMSON REUTER Citation Reports) in their respective fields. His work in Prostate Cancer detection using multi-parametric MRI has been awarded twice with the Summa Cum Laude (top 5%) and once with Magna Cum Laude (top 15%) from the flagship conference in MRI (ISMRM) with more than 6000 attendees every year. He is also one of the developers of a popular open-source software for tomographic image reconstruction, STIR. STIR has been awarded the Rotblat Medal for the most cited research paper published by Physics in Medicine & Biology out of more than 3,000 articles since 2012.

Dr Dikaios was recently awarded the First Grant of the UK's Engineering and Physical Sciences Research Council to work on novel image reconstruction techniques with application to proton radiotherapy for optimisation of cancer treatment.
