Roi Cohen Kadosh (
Hebrew: רועי כהן קדוש, born 1976) is an Israeli-British cognitive neuroscientist notable for his work on numerical and mathematical cognition and learning and
cognitive enhancement. He is a professor of Cognitive Neuroscience and the head of the School of Psychology at
the University of Surrey.
In 2009 he received a
Wellcome Trust Career Development Fellowship to move to the University of Oxford where he established his lab. In 2021, he moved to the
University of Surrey to take headship of the School of Psychology.[1] In 2021 he also founded Cognite Neurotechnology Ltd,[2] a start-up company that uses the findings from his studies to combine
AI and
neuromodulation to provide personalised, safe, and painless technology to improve cognition and learning for therapeutic or augmentation purposes.
Research
Numerical cognition
Cohen Kadosh started to work on
numerical cognition under the supervision of
Avishai Henik. His work has focused on how humans represent numbers and the psychological and biological mechanisms that support superior,[3] typical,[4][5] and impaired numerical understanding,[6] a research with implications for a wide range of fields including
Psychology,
Education, and
Neuroscience. His work in this field has led to significant changes in several dominant theories of numerical cognition.[7][8]
Synesthesia
Cohen Kadosh has revealed some of the cognitive and perceptual principles of
synesthesia[9][10] and its neurobiological mechanisms,[11][12][13] which has implications for the field of
neuroplasticity and learning. He has also suggested that the origins of synesthesia might be due to a failure in cortical specialization during infancy and childhood.[14]
Cognitive enhancement
Cohen Kadosh has been one of the pioneers in combining cognitive training with non-invasive brain stimulation to show its impact on cognition,[15][16] learning,[17] and brain functions.[18] In the last years he has extended his work to examine the role of individual differences at the psychological[19][16][20] and biological level[11] on the impact of brain stimulation on behaviour, those allowing a better mechanistic understanding of brain stimulation and learning. In the last years he has extended his research to the field of attention by showing the ability to modulate sustained attention using non-invasive
brain stimulation and working together with
Tech Innosphere Ltd, to find a non-pharmacological, safe, and long-lasting solution for children with
Attention deficit hyperactivity disorder (
ADHD), and with
Cognite Neurotechnology Ltd to find effective and personalised solutions to improve attentional abilities in healthy adults.
Neuroethics
Cohen Kadosh has collaborated with neuroethicists to highlight the implications of brain stimulation for cognitive enhancement[21] and shape the current regulation.[22]
Select awards and honours
He has received more than 60 awards, grants, and honours which include:
In 2009 he received The Sieratzki-Korczyn Prize for Advances in the Neurosciences.[23]
In 2010 he received the Career Development Award from the Society for Neuroscience.
In 2013 he received the Paul Bertelson Award from the European Society for Cognitive Psychology.
In 2015, his book, The Stimulated Brain, was given an Honorable Mention for Biomedicine & Neuroscience at the 2015 PROSE Awards from the Association of American Publishers.[25]
In 2015 he received the Professorial Distinction Award, University of Oxford, UK.
In 2016 he received The International Mind, Brain and Education Society (IMBES) Early Career Award.
In addition, he has contributed to the wider national and international academic community's general life through various roles and activities including advising policymakers, non-governmental agencies, and commercial companies, co-founding international scientific societies, and chairing and serving as a committee member on grant panels.
