Alexis Souchet



I am a Researcher in cognitive ergonomics. I work on virtual reality, Human-AI collaboration for decision making, human factors, psychophysiological measures and detection of cognitive load, acute stress and VR side effects. I'm also trying to raise awareness of immersive technologies' ecological impacts.
