About

My research develops digital biomarkers of movement-related health from wearable sensor data, using interpretable artificial intelligence, with a particular focus on healthy ageing. I work with free-living data recorded continuously as people go about daily life, rather than short laboratory tests, and use interpretable machine learning for early detection of frailty, mobility decline and fall risk in older adults. A central concern is that model output should be examinable and clinically usable, so that it supports decision-making instead of asking clinicians to trust a black box.

Before CUHK I completed a PhD in Human Movement Sciences at University of Groningen, University Medical Center Groningen, supervised by Prof. Dr. Claudine Lamoth, Prof. Dr. Michiel Reneman, Prof. Dr. Bert Otten.
