Academic Supervisor: Bernhard Müller
Co-supervisor: Sverre Gullikstad Johnsen

Objective:
Provide experimental support to validate a CFD model.

Main project:
Modeling of obstructive sleep apnea by fluid-structure interaction in the upper airways
Develop mathematical model to predict the response to OSAS treatment.
sleep related breathing disorder
caused by collapses of the
pharyngeal walls
cardiovascular diseases
up to 40% of the patient unchanged
after surgery
