Ian Rousseau

Founder, Hexisense


Ian Rousseau is an entrepreneur and physicist working at the intersection of vacuum, semiconductor, and optical technologies.  He studied physics at the Massachusetts Institute of Technology (MIT) and was a Fulbright scholar at the University of Constance in Germany.  Ian returned to his native Vermont and caught the startup bug while working for a SME designing and fabricating bespoke diffractive and holographic optics.  The startup Hexisense was spun-out of Ian’s later Ph.D. thesis in gallium nitride semiconductors at the Swiss Federal Institute of Technology (EPFL) in Lausanne.  Ian has co-authored three patents and nine academic publications, speaks three languages, and enjoys the mountains in his free time.
