Michael Lexa received his B.S. degree from the University of Notre Dame in 1993, his M.S. degree from the University of Colorado at Boulder in 1996, and his Ph.D. degree from Rice University in 2008 all in electrical engineering. From 1996-1998 he served in the U.S. Air Force, Space and Missile Systems Center, Test and Evaluation Directorate, Kirkland AFB NM where he supported test flights of the National Ballistic Missile program. In 1999, he was assigned to the U.S. Air Force, National Air Intelligence Center, Wright-Patterson AFB OH. In 2003, he interned at the MIT Lincoln Laboratory in Lexington, Massachusetts to work on the some of the theoretical aspects of data fusion.
Research Interests
Michael Lexa's research interests and activities lie broadly in the areas of statistical signal processing theory and information theory.
