Matthew T. Hatem

My name is Matthew Hatem.  I am a graduate student at the University of New Hampshire and a Senior Software Engineer at IBM.  I am a member of the UNH Artificial Intelligence Group.  I am currently working with Professor Wheeler Ruml in the area of heuristic search.  I am interested in parallel, distributed and external memory search algorithms.

I enjoy participating in open source software projects.  In previous years I did some work with the Eclipse project and at one time I was a committer.  I spent a little time investigating enhancements to the OpenSocial 2.0 specification and implementation within Apache Shindig.  More recently I have been using Apache UIMA, Apache Lucene and Lemur Indri.
