Gilles F. Feutmba received his Bachelor of Science in Physics from the University of Buea, Cameroon in 2011. He enrolled to the European Master of science in Photonics Engineering in 2015 and joined the Photonics Research Group in September 2017. His research focus on the dense integration of Lead zirconate titanate (PZT) based nonlinear elements for on-chip second order nonlinearity.
