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, bias/variance analysis of committees); opinion mining, and social media analysis and information summarization (we have a start-up, SomaTech, in this area).


Please visit the Biometrics research group and SomaTech webpages, if interested.
