Javier Tejero holds a Ph.D. from the University of Barcelona (UB, Spain) and is currently Professor of Chemical Engineering at that University, where he teaches courses on Catalysis and Chemical Reaction Engineering. He has coordinated the Bachelor in Chemical Engineering, and actually coordinates the Master in Chemical Engineering at UB. He coordinates the research group “Catalysis and Applied Kinetics Group” at the Faculty of Chemistry, UB. His research interest have been focused on the acid catalysis by ion-exchange resins on reactions such as etherification of alcohols with olefins, dehydration of linear alcohols, oligomerization of linear and branched olefins, that is compounds able for fuels reformulation. Recently, his research is focused on the transformation of biomass into biofuels and bio-compounds able to substitute the oil-derived counterparts, as well as on the use of metal-supported ion exchange resins. He has published about 120 research papers, three books on Chemical Engineering and several works on teaching innovation in Chemical Engineering.
