My recent focus has been on developing new, efficient mathematical algorithms for information retrieval and data mining applications. I was at IBM Almaden from November 1997 - August 1999, where I got interested in pattern recognition in large data sets. I briefly worked as a PostDoc in the Computer Science Dept from May 1997 - November 1997 before moving on to IBM's Almaden Research Center. I finished my PhD in Computer Science from UC Berkeley on May 23, 1997. Class Visualization of High-Dimensional Data with Applications.
