She was promoted to Associate professor in Chemistry at UdG in 2008. She performs teaching and research in the area of analytical and environmental chemistry. Her research is mainly focused on the development of new separation techniques for the monitoring and availability of toxic pollutants in the environment. She is renowned for her pioneering research on polymer inclusion membranes that has allow an in-depth understanding on the processes affecting the separation system and their application in the area of environmental analysis. Recent projects have focused on contaminants such as As, Hg, Cd, pesticides and antibiotics. Claudia Fontas has published 75 refereed articles and 2 book chapters and has supervised 5 PhD thesis. She is currently co-supervising 4 PhD thesis in collaboration with the Universities of Bejaia and Tizi-Ouzou (Algeria). She has participated in several competitive research projects including national R & D & I projects as a team member researcher, and two as a First Chief Investigator (periods 2014-2016 and 2016-2019). Claudia Fontas is member of the editorial board of the journal Membranes (MDPI) and the guest editor of three special issues on liquid membranes and has recently been appointed as the Editor-in-Chief for 'Membrane Preparation and Characterization' section of this journal.
