Dr. Brown is the Dean of Faculty and Academic Programs at the Eisenhower School for National Security and Resource Strategy.  Formerly the Chairman of the Department of National Security Studies at National Defense University, Ft. Lesley J. McNair, in Washington, D.C., he has also served as a visiting professor of Science and Technology Studies at the Virginia Polytechnic and State University in Falls Church, Virginia.

 In addition to dedicating much of the past decade to understanding the U.S. defense industrial base, he has also studied national security and homeland security policy extensively. He has taught courses to senior military officers and civilians from across the U.S. Government on the defense industrial base, national security policy, and a variety of technology issues, to include the linkages between technology and infrastructure.

Dr. Brown received his Doctorate of Philosophy in History from the University of California at Santa Cruz in 2000. His doctoral dissertation, Annihilating Time and Space: The Electrification of the United States Army, 1875-1920, was the first such study of early twentieth-century military infrastructure development (with attention given both to systems and the institutional changes that took place as new technologies were introduced into the force structure of the U.S. Army). More recently, he has published on defense acquisition history and policy; edited volumes on the subject of nation-building; and contributed to the publication of a widely-used handbook on the U.S. Government interagency process. 

Dr. Brown served on the Board of Directors of the U.S. Border Patrol Foundation from 2009 to 2013.
