Greg Allen's Home Page

I am a Senior Engineering Scientist in the Enabling Capabilities Division of the Advanced Technology Laboratory at Applied Research Laboratories, The University of Texas at Austin. I have previously been a member of both the Special Warfare Division and the Sonar Development Division. I received my Ph.D. in the UT Electrical and Computer Engineering Department under the supervision of Professor Brian Evans.
