Main research interests have been in the area of Environmental/Industrial BioEngineering, with special focus on the development of sustainable bioprocesses for the removal of pollutants from water and wastewater streams and for the exploitation of industrial wastes for the production of biopolymers and bulk chemicals.
Within this research area, published more than 200 papers in scientific journals with peer review. She is the co-author of 18 Book Chapters. Presented more than 200 oral presentations in International conferences. Is co-author of 4 National patents and 6 International patents. Coordinated 20 national and international projects (team leader), out of which 12 European Projects and 6 were co-funded by industrial companies, and participated as team member in 22 research projects. Co-supervised 20 PhD students and is currently co-supervisor of 11PhD students. Her scientific work has been distinguished with several awards and she was the winner of the Solvay & Hovione Ideas Challenge SHIC’08 Prize- Solvay prize in 2008. Nominated and Elected to the Portuguese Academy of Engineering in 2009 and Elected as IWA Fellow, September 2010. She is Editor of the Water Research (Elsevier).
