Ana Fred received the M.S. and Ph.D. degrees in Electrical and Computer Engineering, in 1989 and1994, respectively, both from Instituto Superior Técnico (IST), Technical University of Lisbon, Portugal. She is a Faculty Member of IST since 1986, where she is currently a professor with the Department of Biomedical Engineering, and previously with the Department of Electrical and Computer Engineering. She is a senior researcher at the Pattern and Image Analysis Group of the Instituto de Telecomunicações. Her main research areas are on pattern recognition, both structural and statistical approaches, with application to data mining, learning systems, behavioural biometrics, and biomedical applications. She has done pioneering work on clustering, namely on cluster ensemble approaches. Recent work on biosensors hardware (including BITalino – www.bitalino.com) and ECG-based biometrics (Vitalidi project) has been object of several national and international awards, as well as wide dissemination on international media, constituting a success story of knowledge transfer from research to market. She has published over 160 papers in international refereed conferences, peer-reviewed journals, and book chapters. She received the "Best paper award in Pattern Recognition and Basic Technologies", awarded by the IAPR, for the paper “Learning pairwise similarity for data clustering”. She is the editor of over 40 books with the proceedings of international workshops that she organized or co-chaired, including S+SSPR 2004 (Lisbon), S+SSPR 2006 (Hong Kong), ICPRAM, ICAART, KDIR, and BIOSTEC. She is the editor of 39 Springer books of selected papers. She has been Associate Editor-in-Chief of the journal Pattern Recognition.
