I am currently a member of Mathematical Sciences Department at IBM Research, working on a range of predictive modeling problems and business analytics applications.
Prior to joing Math Department I was a member of the Visual Analysis group at IBM Research. Some of the projects I have worked on are image semantic modeling, semantic based image retrieval and navigation, Bussines@Glance, and
brain tumor analysis and reconstruction.
At Bell Laboratories, I was involved in the design of an image retrieval system for electronic retailing, interior decoration, design and digital museums. I also worked on color quantization and
processing of palletized images, as well as on the color features and color matching algorithms that are better matched to human perception.
During my graduate studies I was mainly involved in the design and applications of wavelets and filterbanks for texture characterization. I also did a lot of work in medical imaging, particularly in ultrasonic tissue characterization and segmentation.
Research Interests
My research interests include multidimensional signal processing, financial modeling, patern recognition, human perception and medical imaging. I am currently a Member of the IEEE Multidimensional Signal Processign Committee and an Associate Editor for the IEEE Transactions on Image Processing
