Short CV

Filipe Figueiredo (1970) graduated in Ceramics and Glass Engineering (1993) from the University of Aveiro (UA) and obtained a PhD from the same University in April 1999, with a thesis on composite mixed conducting materials for application as cathodes in solid oxide fuel cells. Six months after completing his PhD, he joined the Open University in Lisbon, where he was appointed to a Tenured Auxiliary Professor position in April 2006. Filipe was deeply involved in teaching using distance learning methodologies and the implementation of e-learning at the Open University.  He had also an active role in several bodies of the University, notably as an elected member of the Senate and of the Coordinating Commission of the Scientific Council. At the same time, he collaborates with the Aveiro Institute of Materials - CICECO of the University of Aveiro, becoming a full member in December 2004. His research interests are centred on the relationships between structure, microstructure and electrical and electrochemical properties of ionic and mixed conductors for application in electrochemical energy conversion systems such as fuel cells, electrolysers and gas separation membranes. In March 2008, after nine years in Lisbon, Filipe requests a long-term unpaid leave status to embrace a research career at CICECO under the Ciência 2007 Program, where, besides maintaining and expanding his research in ceramics, he creates a new research area and laboratory dedicated to polymer and hybrid materials for low temperature fuel cells and related applications. Filipe is since February 2014 a Principal Researcher at CICECO, where he coordinates the research group G3 - Materials for Energy and Functional Surfaces. He supervised to completion the work of 5 PhD students, 10 post-doctoral fellows and 13 MSc Students. He has coordinated or coordinates 8 projects corresponding to a total funding of 2.64 M€ , and has played important roles in more than 15 other projects (National and European). Filipe has contributed to ca 150 papers in international refereed journals, with more than 3800 citations and a corresponding h index of 35. He has presented a similar number of communications, including 8 invited lectures at international conferences, having received 4 awards. Filipe has been involved in several evaluation panels for project, PhD and postdoctoral grants. Current scientific interests are polymer electrolyte for intermediate temperature PEM fuel cells, organic-inorganic hybrids with proton conductivity, including metal-organic frameworks, bio-based polymers for PEMFCs, particularly concepts based on bacterial cellulose, and the electrical properties of graphene-based composites.
