Elena Gómez Costas graduated in Chemical Sciences at the University of Vigo (Spain) in 2001. She started her research career in 2004 when she joined the Advanced Separation Processes Group in the area of Chemical Engineering of the University of Vigo, as a Ph.D. student and she enjoyed of a pre-doctoral stay at the Federal University of Rio de Janeiro. In 2008 she obtained her Ph.D. degree at the University of Vigo obtaining the Thesis Extraordinary Prize. After the Ph.D. degree, she was selected by FCT for a post-doctoral grant, under the supervision of Professor, Maria Eugénia Rebello de Almeida Macedo (LSRE) from January 2009 to October 2010 with a new line of research focused on the study of separation of aromatics from alkanes with ILs. After this, she continued to develop her research career at the University of Vigo (Ángeles Alvariño Program, Xunta de Galicia, Spain) and she expanded her research experience in the separation of mixtures with ILs through liquid-liquid equilibrium. During these years she maintained a close contact with the group of Professor Eugénia Macedo, and she carried out stays at LSRE from October 2010 to January 2011 and from October 2011 to December 2011. Currently, she is a post-doctoral researcher at LSRE-LCM under the guidance of Professor Eugénia Macedo on the field: study new choline and amino acids- based ionic liquids (CAAILs) or Deep Eutectic Solvents -based aqueous two-phase systems (ATPS) for separation of biomass-derived building blocks and other biomolecules.
