After completing his first Master degree at Ecole Polytechnique, Cyril Crawford decided to specialize in Civil & Environmental Engineering at Imperial College London in 2019. When the COVID-19 pandemic broke out, he volunteered to help in several hospitals from AP-HP in Paris, where he led a research consortium on aerosol contamination risks in an ICU (Bichat Hospital, Polytechnique & Dassault Systèmes). After graduating, he joined Dassault Systèmes in 2021 in order to continue modelling work on the topic of airborne contaminations in healthcare settings.
