Celestine Santosh is a Clinical Consultant Neuroradiologist working in Glasgow, which is one of the largest Neurosciences Unit within the UK. Having started in Clinical Radiology 33 years ago, he then specialised in Neuroradiology over the last 27 years. He has worked in many large specialised hospitals in India and the UK and has been in Glasgow since 2000. He conceived the Glasgow Oxygen Dependent (GOLD) techniques working as a clinician, with a special interest in stroke. This allowed him to understand the need to accurately assess the Penumbra with imaging and also the need for additional treatments for stroke. He was successful with the team, in getting grants and funding for the pre-clinical work. Dr Santosh is a co-founder of Aurum Biosciences Ltd, a practicing clinician and inventor, so in an ideal position to take the GOLD techniques into clinical practice.
