The Data

Reading movement in real time

Gait analysis starts with raw inertial signals. Below is a live illustration of multi-IMU accelerometer streams — the periodic spikes mark heel-strike events my algorithms detect to estimate cadence, foot clearance, and balance.

What I Do

Research at the intersection of sensing & movement

My work integrates multiple sensing modalities into real-time systems that measure, interpret, and respond to how people move.

Wearable IMU Sensing

Multi-sensor IMU networks (Xsens DOT V2, Awinda MTw) for comprehensive, body-worn gait analysis.

Gait Analysis

Real-time obstacle detection, foot-clearance estimation, and terrain classification during walking.

Haptic Feedback

Adaptive sensory cueing for gait correction and fall prevention, driven by live sensor data.

Android Development

Mobile apps for on-device sensor acquisition, visualization, and analysis using the Movella DOT SDK.

Signal Processing

MATLAB pipelines for multi-sensor synchronization, data fusion, and biomechanical feature extraction.

Fall Prevention

Translating research into practical solutions for mobility and quality of life in elderly adults.
