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.


If you want to see me, please look at my schedule on the top part of this page and check any available slot between 9:30 and 4pm and email me if you want to make sure I am here; otherwise just stop by (preferred).  I usually go to lunch at 12 and I may not be in school Friday afternoons.
