Sebastien Ourselin

Head of the Translational Imaging Group, UCL

Sebastien Ourselin is Head of the Translational Imaging Group (TIG) within CMIC, Director of the EPSRC Centre for Doctoral Training in Medical Imaging, CMIC Deputy Director, Head of Image Analysis at the Dementia Research Centre, and Professor of Medical Image Computing. He obtained his PhD in Computer Science from INRIA (France) in the field of medical image analysis under the supervision of Prof. Nicholas Ayache. He has published over 200 journal and conference articles. He is an associate editor of IEEE Transactions on Medical Imaging and a member of the Editorial Board of Medical Image Analysis. He is a MICCAI Board Member since 2008, and was elected Executive Secretary of the MICCAI Society (2009-2012).

Prof. Ourselin is leading the translational imaging research program between CMIC and the Institute of Neurology, and has established in collaboration with Prof Nick Fox a new imaging unit at Queen Square to deliver novel imaging biomarkers for clinical trials.

His main research interests include image registration, segmentation, molecular imaging, atlas conception, statistical shape modeling, surgical simulation, image-guided therapy and minimally invasive surgery. He has been involved in a broad range of clinical projects, including neuroimaging, neurosurgery, computer-assisted cardiovascular surgery, radiotherapy treatment, colonoscopy, and orthopaedic imaging. His research is often collaborative, involving clinical and commercial partners.

Before joining UCL, he founded and led the CSIRO BioMedIA Lab (2003-2007), Australia. He headed a 17-strong government funded research group in biomedical image analysis and surgical simulation. He led the development of the MILX platform, now distributed to Australian hospital partners. He also established and led the image analysis research program of the AIBL study, and the development of a successfully commercialized surgical simulator for colonoscopy. In less than 4 years, his laboratory became the research leader in medical image analysis and surgical simulation in Australia. BioMedIA Lab is still existing and thriving (see: In Australia, he is still currently adjunct A/Prof at the University of Queensland (joint appointment Faculty of Health Sciences and School of Information Technology and Electrical Engineering), adjunct A/Prof at the University of New South Wales, Graduate School of Biomedical Engineering. He is also Honorary Medical Physicist at Westmead Hospital (Sydney, Australia), Department of Radiology. Until December 2007, he was President of the Australian Pattern Recognition Society (

He has been actively involved in conference organization nationally and internationally. He is chair of the Image Processing conference of SPIE Medical Imaging (2012-2015). He has been part of the MICCAI Program Committee since 2005, and was Program co-chair of MICCAI 2007. He was co-chair of MMBIA 2012 in Breckenridge (USA) and FIMH 2013 (London), and is currently General Chair of WBIR 2014, IPMI 2015 and MICCAI 2016.
