Ricardo Santos graduated in Environmental Engineering at Universidade de Aveiro in 1996 and got his PhD in Chemical Engineering from Faculty of Engineering of University of Porto (FEUP) in 2003. The PhD was made at LSRE and the research topic was: Mixing Mechanisms in Reaction Injection Moulding. After the PhD he was Post-Doc for one year, in an industrial project on the rheology of Self-Compacting Concrete. From 2004 to 2006 he was a lecturer at the Polytechnic Institute of Viana do Castelo, where he taught courses on design of water and wastewater treatment plants. Since 2006 he has been at the LSRE-LCM Associated Laboratory as Research Assistant researching on the field of mixing in chemical and biological reactors. One of his main fields of interest is the mixing in reactive polymerization reactors, a field he works on since 1997 when he first came to LSRE. In 2013 he was one of the founders of a spin-off company, MICE-molds, that is taking to industry the main findings of the research on Reaction Injection Moulding at the LSRE-LCM. Recently, he has been researching on mixing in NETmix reactors, in single-phase and multiphase flow for environmental applications. Since 2017 he is the leader of a research project funded by FCT on this topic (HXmeso).
