Professor Tony David, Vice-Dean Academic Psychiatry said: ‘Professor Aarsland is one of the most outstanding researchers in old age psychiatry and we are delighted that he will be joining us. He will bring with him a network of international collaborators and already has well established links with researchers here notably Clive Ballard and Ray Chaudhuri. Dag has worked in all aspects of old age psychiatry from basic science to applied health research. He is a natural team player and team-builder and will be a huge asset to the IoPPN and King’s College.'

As well as heading the Centre, Prof Aarsland contributes to several new healthy brain ageing and dementia research initiatives. He is also a clinician within South London & Maudsley NHS Trust and will help in training the next cohort of old age psychiatrists.
