Catherine Signoretty

Research Scientist

Catherine got her degree in Chemistry at the University of Jussieu, Paris, France. Yes, France is her native country and she still has the accent and a bizarre attitude that she cannot lose. She worked in the environmental field with multiple commercial companies for a few years before joining EHL/TOAC in 2013. Catherine loves to be outside hiking, camping, skiing, canoeing, you name it. She is also very fond of the 3 F's (family, friends, and food...especially wine).
