I turn raw, messy wearable and health data into clear, validated insight at scale — combining statistics and modern machine learning to understand how people move.

Yong Kuk Kim

About

I'm a computational biomechanics researcher who recently completed a doctorate (Dr. Sc.) at ETH Zürich, in the Laboratory for Movement Biomechanics under Prof. William Taylor and Dr. Navrag Singh. My work sits at the intersection of engineering, biomechanics, wearable sensing, machine learning, and clinical translation — developing objective measures of human movement that work beyond specialised laboratories.

In practice, I turn raw, messy wearable and health data into clear, validated measures of movement — across small, controlled laboratory experiments, a 2,000+ participant ageing cohort, and real-world wearable studies. An engineering foundation (MEng, UCL) underpins how I move fluently between signal processing, statistics, physiology, and computation, rather than staying inside any single discipline.

I reason from first principles and pair modern tools — including AI and LLMs — with scientific judgement: I use them to accelerate exploration, analysis, and writing, while relying on domain reasoning to know when to trust a result and when not to. I'm at my most useful on open-ended, interdisciplinary problems, where the right questions emerge through building and iteration.

Ultimately, I'm motivated by problems where engineering, AI, and clinical science meet, and where rigorous analysis leads to practical improvements in how we understand human health and movement. Outside work, I enjoy skiing, wake surfing, handstand training, tennis, and travel.
