Andrea Carvajal is a Chemical Engineer and holds a Master’s Degree in Engineering Sciences from the University of Santiago, Chile. She completed her master’s and doctoral degrees in the Department of Chemical Engineering and Environmental Technology at the University of Valladolid (Spain), where she specialized in anaerobic digestion, focusing on both thermal and biological pretreatments. She is currently a professor in the Department of Chemical and Environmental Engineering at the Federico Santa María Technical University (Santiago, Chile), where she teaches and conducts research. Her primary focus is the study of biochemical processes for the recovery of urban and agro-industrial residues to produce high-value compounds, thereby developing the concept of biorefinery. Specifically, her latest projects have focused on the development of a methane-arrested anaerobic digestion process in leaching bed reactors for producing short-chain organic acids and their application in the production of polyhydroxyalkanoates.
