Biography
Stefanos Zafeiriou was born in Thessaloniki, Greece in 1981. He received the B.Sc, degree in Informatics with highest honors in 2003 and the Ph.D degree in Informatics in 2007, both from the Aristotle University of Thessaloniki, Greece. Currently, he is a Research Fellow with the department of Computing, Imperial College London, UK. He has received various scholarships and awards during his undergraduate, Ph.D. and postdoctoral studies and has participated in more than 10 European, British and Greek research projects. From 2003 to 2007 he was a research and teaching assistant in the department of Informatics at Aristotle University of Thessaloniki. During 2007-2008 he was a senior researcher in the same department. During 2008-2009 he was a research associate in the department of Electrical and Electronic Engineering, Imperial College London, UK and a postdoctoral scholar of the State Scholarship Foundation of Greece. During 2009 he also served as a Visiting Researcher at the University of Houston, Texas, USA. He has co-authored more than 20 journal papers in face recognition/verification/alignment/tracking and facial expression recognition, 14 of which in the most prestigious journals in his field like IEEE Transactions on Pattern Analysis and Machine Intelligence, IEEE Transactions on Image Processing, IEEE Transaction on Visualization and Computer Graphics, IEEE Transactions on Neural Networks, Data Mining and Knowledge Discovery etc..
