Guillaume Painchaud-April received his PhD in 2013 from the department of Physics and Physics Engineering at Université Laval, Quebec, Canada for his thesis on the use of the scattering matrix in the analysis of optical dielectric resonators. In 2012, he joined Olympus as an industrial physicist, and his current role at Evident is data scientist. His work relates to the physical modeling of wave phenomena in acoustic and electromagnetic inspection systems, on their deployment, and on the use of statistical methods and machine learning methods to improve the reliability of NDE in commercial systems.
