ACKNOWLEDGMENTS
There are several people that I would like to acknowledge for their support of this
endeavor.
My wife, Rachael, who has shown me unwavering support for the 23 years that
we have been together. I could never have accomplished what I have without her. I also
want to thank my children Christina, Gwendolyn, Alannah, Joshua and Destini. Their
faith in and love for me is a constant source of strength each and every day.
My Committee Chair, Dr. Eric Dietz for his guidance and mentorship throughout
my dissertation and as my advisor while attending Purdue. My committee Dr. Yang, Dr.
Xu, and Dr. Springer for their insights and guidance throughout the dissertation process.
My thanks to Dr. Eugene "Spaf" Spafford, Director Emeritus of the CERIAS Program,
because without his urging and guidance I might not have had this opportunity in the first
place. To Mrs. Marlene Walls whose help and guidance through the administrative
aspects of graduate life at Purdue saved me many hours of work and needlessly running
around campus.
I want to acknowledge U.S. Army Cyber Command for selecting me as one of
their FY15 Army Cyber Scholars. They saw in me the potential as a Cyber leader for the
Army and demonstrated their confidence in that potential by selecting me. What I have
accomplished over the last two years demonstrates that their confidence was well
founded.
I wish to acknowledge Colonel Timothy Frambes, Lieutenant Colonel Charles D.
(Dean) Smith, and Tommie L. Walker, Lieutenant Colonel (USA Retired) whose
mentorship and leadership has been invaluable. I continually seek to emulate and
incorporate their leadership styles into my own. I also want to thank James Lerums
Colonel (USA Retired), Major Patrick Glass, and Captain Chris Baker fellow students
and colleagues in military life. You were always there willing to give me the azimuth
check as I made my way through my scholarly pursuits.
