After a Master’s Degree in Chemical Engineering (Instituto Superior Técnico, Lisbon) I pursued a PhD in heterogenous catalysis developing a multi-technique approach to the characterization and rationalization of bifunctional catalysts combining, XAS (ESRF, Grenoble), STEM (IPCMS, Strasbourg), NMR (CRMN, Veilleurbanne) and DFT. Since I have joined the Catalysis by Sulphides department at IFPEN working on the development of bifunctional hydrocracking catalysts. I have recently expanded my research to chemical plastic recycling, biomass conversion and biobased product synthesis (PEPR B-BEST, project Optisfuel).
Development of new Hydrocracking catalysts
"PEPR" Bioproductions/B-Best - Project Optisfuel - co-supersivion of a PhD on higher alcohol synthesis from syngas in collaboration with IRCELYON
Supervision of a PhD on chemical recyclong of polyolefins by cracking in collaboration with CP2M
