Lucian John-Ross Bezuidenhout
About me
I am an Assistant Professor at the Division of Physiotherapy, Karolinska Institutet. I obtained my Bachelor’s degree in Physics and Applied Mathematics in 2010, followed by an Honours degree in Physics in 2011 and a Master’s degree in Applied Physics in 2014 from Nelson Mandela University. I completed my PhD in Geophysics at the same institution in 2018.
Following my doctoral studies, I undertook postdoctoral research at the African Observatory Network (2018–2020) in South Africa and later at the Department of Neurobiology, Care Sciences and Society at Karolinska Institutet (2021–2024).
My academic background in physics and geophysics has provided a strong foundation in quantitative analysis, signal processing, and data modelling, which I have since applied to health research.
Research
My research focuses on promoting physical activity and reducing sedentary behaviour in people with neurological conditions. I investigate how behavioural and environmental factors influences activity patterns and recovery in everyday life, using objective measurement methods to capture real-world behaviours.
I also develop and evaluate digital health solutions, including mHealth and AI-based interventions, to support long-term self-management of physical activity. In addition, I use functional near-infrared spectroscopy (fNIRS) to study brain activity during ecologically valid tasks in both healthy older adults and individuals with neurological conditions.

- Mind in Motion: Exploring Motor-Cognitive Interference while performing complex walking and dual-task in people post stroke.Promobilia Foundation1 January 2025 - 31 December 2027The overarching purpose of this project is to clinically assess motor cognitive performance during complex walking and dual-tasking conditions by integrating a non-invasive measure of brain activity i.e. fNIRS and objective assessments of motor behavior in people post stroke. The goals of this project are to 1) validate complex walking protocols developed previously for people with neurological diseases for evaluating motor-cognitive performance and assessing brain activity using fNIRS in individual’s post-stroke. 2) investigate differences in cortical activity with walking performance during complex walking tasks and compare it to healthy adults, people with Parkinson’s disease and multiple sclerosis3) establish correlations between fNIRS-derived cortical activity and walking performance metrics (i.e., gait speed and stride length) to gain insight into the relationship between brain activity, cognitive performance, disease severity and functional outcomes in people post stroke.
