Mara Freire

Mara G. Freire graduated in Chemistry - Analytical Chemistry in 2003 by University of Aveiro, Portugal, and received the "Best Chemistry Student Award" from Dow Portugal. By the end of 2007 she completed her PhD in Chemical Engineering by University of Aveiro, having during her PhD studies trainees at Federal University of Rio de Janeiro, Brazil, and Claude Bernard University, Lyon, France. From the beginning of 2008 to the middle of 2013 she was a post-doctoral researcher at Instituto de TecnologiaQuímica e Biológica, ITQB2, New University of Lisbon, Portugal. Since June of 2013, Freire is an Assistant Researcher at CICECO, University of Aveiro, Portugal (

Scientific Interests:
From 2004-2007 and during her PhD investigations, Freire has been dedicated to the study of perfluorocarbons to be used in blood substitute formulations or in biological reactors. In this field, Freire has addressed gas-liquid and liquid-liquid equilibrium measurements and the study of their emulsions stability. In the past 5 years, Freire has been working with a new class of ubiquitous compounds – ionic liquids. The scientific interest devoted to these fluids includes their thermophysical characterization, the understanding of their solubilities in aqueous salt solutions and their use as extractive solvents for value-added compounds. In particular, ionic-liquid-based aqueous biphasic systems have been investigated for the extraction, concentration and purification of alkaloids, antioxidants, endocrine disruptors, pharmaceuticals, among others. Besides their study as potential extractive platforms, the molecular-level mechanisms responsible for their two-phase formation have been deeply investigated. In addition to the participation as a team member in 7 other finished/on-going research projects, Freire is an actual principal investigator in a FCT funded project and in an European Research Council (ERC) Starting Grant (IgY Technology: A Purification Platform using Ionic-Liquid-Based Aqueous Biphasic Systems, 1.4 M€).
