Past Member
Lecturer at Lincoln University, UK
Biography
I received the diploma degree in electrical and computer engineering from Aristotle University of Thessaloniki, Greece, in 2004 and the M.Sc. and Ph.D. degrees in signal processing and computer vision from Imperial College London, U.K., in 2005 and 2009, respectively. After the completion of my Ph.D., I was working as a Research and Development engineer with Imperial College/Selex Galileo. Since June 2010, I am a Research Associate in the Department of Computing at Imperial College working with Prof. Maja Pantic on face analysis.
Face analysis:
Facial point tracking,
Face registration
Biometrics & Behaviometrics:
Subspace learning for face recognition
