Biography

Irene Kotsia received the diploma and PhD in Informatics from the Aristotle University o Thessaloniki, Greece in 2002 and 2008, respectively.  From February  2008 to August 2009 she was a researcher and then a postdoctoral researcher with the Informatics and Telematics Institute, CERTH, Thessaloniki, Greece. Since September 2009 she has been a Research Associate with the Multimedia and Vision Research group (MMV) in School of Electronic Engineering and Computer Science, Queen Mary University of London. Since January 2012 she has been a part time research associate at i-bug group at Department of Computing, Imperial College London. She has also been awarded a three year Fellowship Co-Financed by the European Union and the Greek State, Operational Programme ‘Education and Lifelong Learning’, ‘Supporting Postodoctoral Researchers’.  She has coauthored many journal publications in a number of scientific journals, including IEEE Transactions on Image Processing, IEEE Transactions on Neural Networks and IEEE Transactions on Forensics and Security. Her current research interests lie in the areas of image and signal processing, statistical pattern recognition especially for human actions localization and recognition, facial expression recognition from static images and image sequences as well as in the areas of graphics and animation.
