François Perrin


François Perrin has been teaching physics and chemistry for more than 15 years before joining the firm in 2005. He works with the lawyers to help them understand and dig deeper into the technical aspects of the cases.

He creates visual aids (diagrams, models, side shows) which are inserted into the submissions and communicated as exhibits in the proceedings to help the judges grasp even the most complex technical aspects of the cases.
