My previous work revolves around Machine Learning, Statistical Pattern Recognition, and Information Theory.

Intelligent User Interfaces

I started the Personal Wizards Project, which investigated collaborative programming by demonstration for creating self-help procedures to address computer problems first, and "intelligent" documentation after.

Problem Prediction, Avoidance, and Diagnosis

I worked on several problems related to Software Rejuvenation and capacity management.

Digital Image Databases

During my first years at IBM, I worked on the NASA-sponsored SPIRE Project, which investigated search and retrieval from databases of scientific images. I developed algorithm for searching images by content in the compressed domain, for searching multi-modal databases, and devised high-dimensional indexing methods that support similarity search and linear search (i.e., to find objects that maximize a linear constraint on their features.)

Source Coding

Over the years, I have also conducted research in the area of source coding, in particular on wavelet-based compression, on redundancy of Lempel-Ziv-like coding, and on multiple descriptions.
