Dr Chan is an academic neurologist whose primary area of research is in the detection of Alzheimer's disease (AD) in its earliest stages, prior to the onset of memory problems. To this end Dr Chan is honorary associate professor at the Institute of Cognitive Neuroscience, University College London. His research has been published in the top academic journals including Nature and The Lancet. In particular his work focuses on three themes, namely
- science that translates discoveries made in the fields of cellular and systems neuroscience to early AD diagnosis (example publication: Wood et al. (2018) The Honeycomb Maze: a new behavioral test for hippocampal-dependent spatial navigation and memory. Nature 554, 102-105. View Paper)
- the application of novel technologies to the detection and monitoring of AD (example publication: Howett et al. (2019) Differentiation of mild cognitive impairment using an entorhinal cortex-based test of VR navigation. Brain 142, 1751-1766. View Paper)
- reducing risk of future dementia via engagement in lifestyle activities that boost cognitive reserve and maintain brain health in later life (example publication: Chan et al. (2018) Lifestyle activities in mid-life contribute to cognitive reserve in late-life, independent of education, occupation and late-life activities. Neurobiology of Aging 70, 180-183. View Paper).
Translational research is undertaken in collaboration with Nobel Laureate John O'Keefe at UCL (for a review of the science underlying this approach please see Professor O'Keefe's notes on the Nobel Prize webpages.
Dr Chan's tech-based diagnostic research includes the pioneering use of app- and virtual reality-based tests to identify early AD with greater diagnostic accuracy than the memory tests used currently in clinic. Extending this work, Dr Chan collaborates with computer scientists based at the University of Cambridge and the Alan Turing Institute on the development of wearables-based approaches for detecting early AD. To this end, he is co-lead for a new flagship Alzheimer's Research UK national programme aimed at developing a new "digital diagnostic toolkit" for detecting early stage neurodegenerative disease.
Examples of Dr Chan's research using VR to detect early Alzheimer's disease
Dr Chan has received research grant funding from the Medical Research Council, Wellcome Trust, Alzheimer's Research UK, Alzheimer's Society, Innovate UK and the Alan Turing Institute. His research has been extensively covered by the national and international news media (pls see the Media interviews and news articles page for some examples of media coverage).
