Matthew T. Hatem

Welcome! I recently graduated from the University of New Hampshire with a Ph.D. in Computer Science. While at UNH, I was a member of the UNH AI Group, where I worked with Professor Wheeler Ruml in the area of Combinatorial Search. I am interested in problems where advanced algorithmic ideas can contribute to bringing previously intractable problems within reach. My research focus was in scaling combinatorial search algorithms with parallel processing, external memory, and techniques that achieve linear space complexity. I am currently a Senior Software Engineer at IBM where I work on adapting IBM's Watson technology to new domains.
