My research focuses on the use of ambulatory sensing for human motion analysis. This involves various types of kinematic and/or dynamic sensing. My main expertise is in the field of inertial measurement units, as the versatility of these sensors help us sense/estimate most relevant outcomes of human movement.

I am involved in the following research projects:

- Estimating kinetics directly from inertial measurement units (x-double-dot).

- Measuring and providing feedback to osteoarthritis patients for better quality of life (LoaD).

- Estimating human kinetics using hybrid (data-driven and biomechanics) approaches.

- Improving rehabilitation after hip fractures (Up&Go2.0)

- Improving rehabilitation after ankle fractures (Ankle ReLoad)
