I will be on sabbatical from Aug/2016 to July/2017 at U. of Michigan, USA.











Research Areas:


I work in the general area of Pattern Recognition & Computer Vision, in particular biometrics (signature, fingerprint, voice, biometric privacy and security); document analysis and retrieval (OCR, online and offline handwriting recognition, mathematical expression recognition); machine learning (ECOC); opinion mining, and social media analysis and information summarization (we have a start-up, SomaTech, in this area).
