Turning sensor data into
evidence you can act on.

I help teams turn wearable sensor data into evidence they can act on — whether that's a validation claim, a clinical endpoint, or a product decision. My background spans clinical practice, study design, multi-sensor data collection, and building the analysis tools to make it all reproducible. I've worked across IMU, EMG, PPG, and accelerometry systems, from single-patient assessments to 10,000-participant cohorts.

Multi-Sensor Measurement Systems

IMU, EMG, PPG/ECG, and accelerometry — from single-device setups to synchronized multi-sensor protocols. Practical experience with placement, synchronization, artifacts, drift, and emerging form factors including earables and smart glasses.

Evidence Generation & Study Design

End-to-end study execution: protocols, endpoints, feasibility, adherence, and data-quality checks. Experience across observational studies, RCTs, and longitudinal designs, translating questions into testable, defensible outcomes.

Human Movement & Clinical Domain

Five years of clinical physiotherapy plus a PhD in biomedical engineering. Deep knowledge of gait, functional movement, neuromuscular physiology, and what sensor signals can (and cannot) tell you about real humans.

Real-World Data & Population Analytics

Working with large wearable datasets (10,000+ participants) to derive interpretable activity-pattern metrics — bouts, fragmentation, transitions, intensity distribution — and relate them to health outcomes.

Validation & Regulatory-Ready Measurement

Gold-standard comparisons, reliability testing, synchronization, artifact handling, and transparent error reporting. Building the evidence base so performance claims are defensible for product and regulatory decisions.

Clinical-Technical Translation

Bridging clinical needs and technical implementation. Previously embedded in a product team as clinical consultant, translating end-user requirements into engineering specifications. Comfortable in both languages.

Selected work

Spanning population health, device validation, multi-sensor fusion, and clinical measurement.

Population-scale physical activity analytics

Challenge: Large accelerometry datasets are messy, and summary metrics like "steps/day" miss meaningful behavior patterns.

What I did: Built reproducible Python workflows to quantify activity-pattern metrics (bout distributions, fragmentation, transitions, intensity distribution) from The Maastricht Study's activPAL dataset (~10,000 participants). Also built the activPAL Explorer, an interactive analysis tool for researchers to explore and QA their own activPAL data.

Output: Analysis-ready measures linked to cardiometabolic outcomes, plus a reusable open-source tool.

REALM: Real-world ecological movement with synchronized sensors

Challenge: Current wearable approaches capture the "what" of movement but not the context — you can detect slow walking, but not whether it's caused by cognitive load, stairs ahead, or another pedestrian.

What I did: Co-designed a funded multi-sensor protocol (thigh-worn IMU + ear-worn IMU + smart glasses with egocentric video) to capture movement in real-world conditions: clutter, stairs, turns, social navigation, and dual-task cognitive load.

Output: Public dataset and open-source analysis pipeline for sensor fusion benchmarking. Currently in data collection.

End-to-end wearable gait assessment after ACL reconstruction

Challenge: Lab snapshots miss day-to-day movement strategies during rehabilitation. Wearable-derived endpoints need the same rigor as lab measures.

What I did: Designed a wearable IMU workflow for multi-pace gait and stair tasks in real-world settings. Ran a randomized sham-controlled trial of vibrational stimulation post-surgery. Published the full dataset (COMPWALK-ACL) in Scientific Data for open reuse.

Output: 5 peer-reviewed papers, 1 open dataset, reusable pipeline components. Protocol to publication, end-to-end.

Portable device validation for clinical measurement

Challenge: Can accessible, portable devices produce research-grade measurements with standardized protocols?

What I did: Designed and ran inter- and intra-session reliability testing for handheld dynamometry with a custom 3D-printed fixture. Clear reporting of error, transparent constraints, and practical measurement protocols built to survive real-world clinical variability.

Output: Validated measurement approach and normative data, published and adopted for further clinical use.
