Personal profile
Engineer from the Institut d’Optique Graduate School, Guillaume got his PhD from Ecole Polytechnique. Working at the crossroads between fundamental optics and biology, he was amongst the 2021 recipients of Institut Polytechnique de Paris’ « Best Thesis Award ».
He began his career in South Korea, where he developed new optical interferometry instruments for the study of proteins. As an Associate Professor at the Institut Polytechnique de Paris, he now combines Machine Learning and computational optics to study living organisms using light scattering.
Recent laureate of an international science communication competition organized by Nature, he actively works in science communication and the visual arts.
