Patricia Fernández Requejo graduated in Chemical Sciences at the University of Valladolid (Spain) in 2008. She started her research career in 2008 when she joined the Molten Salts Laboratory in the area of Analytical Chemistry at the University of Valladolid, as a bachelor´s degree thesis. Her research work was focused on the electroextraction of lanthanides on inert and reactive cathodes using molten salts, characterization of the obtained intermetallic compounds as well as their oxoacidity reactions in molten chlorides.

During the period in this research group, she won the First Prize Award of the SNE (Spanish Nuclear Society) to final projects and bachelor´s degree theses 2008. In the following years (from 2009 to 2011), she studied two Master´s Degrees performing the end project in this group. During the Master´s Degree on Advanced Chemical Techniques, she enjoyed a stay in the Atomic Energy Commission and in Alternative Energies (CEA, France).

In 2011, she enjoyed 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 University of Technology of Eindhoven. The research line of the PhD was focused on the study of the extraction of aromatic compounds from alkanes using ionic liquids (ILs) and deep eutectic solvents (DESs) as extraction agents.

In 2015, she obtained her Ph.D. degree at the University of Vigo obtaining the Thesis Extraordinary Prize. After the PhD, she continued working in the application of the ILs and DESs at the University of Vigo from October to December of 2015.

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 flavonoids from agro-food products.
