Joseph Williams - Team Project Manager

Joseph WilliamsI am Joseph Melvin Williams, born and raised in New Orleans, Louisiana. After high school in New Orleans I attend undergrad at Texas A&M University from 1998-2003, where I received a Bachelor’s of Science in Bioenvironmental Science. After graduation I decided to enter the Navy to help pay off the huge amount of student loans I had to take out to attend Texas A&M. I enlisted in March of 2004 as an Information System Technician and started my journey to learn about computers since my background was in biology.

I had a great opportunity to travel the world in the Navy and work with a lot of great leaders and peers. I started taken classes towards my Master’s in Education at Old Dominion University in Virginia in the spring of 2009; I have transferred to taking the classes online since moving to Vermont. After little over seven years of active duty serves in the Navy I decided to try my luck in the civilian world. I started looking for jobs in the Burlington area early this year and applied for the Team Leader position at C3DI. As luck would have it I was offered the position. I completed my move from the D.C. area to Burlington, VT last weekend and I am looking forward to a new chapter of my life at Champlain College


W. N. (Bill) Crane

Bill CraneIn 1971, after 4 years in the Marines, I began a law enforcement career with the U.S. Immigration Service.  I served in the Border Patrol on the Mexican border and as a Special Agent in several U.S. locations.  While based in Washington, D.C. I was selected as the first Special Agent to serve in the Nazi War Crimes Unit in the U.S. Department of Justice and served in that capacity for 3 years.

I subsequently held a number of increasingly responsible positions within the Federal Inspector General community, retiring in 1997 as the Deputy Assistant Inspector General for Investigations at the U.S. Department of State.   I then joined the National White Collar Crime Center in West Virginia as an Assistant Director and also served as Operations Director of the National Cybercrime Training Partnership comprised of law enforcement, academia, and private sector in the development of high-technology training.

In 2005, I accepted a three-year assignment at the Police College in England, heading the High Tech Crime Training unit.  This led, in 2008, to another three-year assignment in New Zealand where I served as Operations Manager for the NZ Police Electronic Crime Lab program with facilities in Auckland, Dunedin and Wellington.  That assignment was completed and I returned to the U.S.  After a bit of eDiscovery work in Florida and some teaching at the Defense Cyber Crime Center in Maryland, I entered my current position at Champlain College, in Burlington, VT, as Associate Professor and Program Director of the Digital Forensics Graduate Program.

My digital forensics experience began while working as a Federal Agent specializing in major frauds.  It became obvious that evidentiary documentation, books, records and other data were being stored on computer systems and that a forensic acquisition and examination of that data would take special skills.  I sought out and acquired training in these skills and upon Federal retirement, I became very active in sharing and teaching these skills to law enforcement.  I have been a frequent lecturer at the Federal Law Enforcement Training Center, the FBI Academy and various police training facilities around the world.  I hold several certifications in the field of digital forensics, represented the U.S. Department of State at a number of domestic and international conferences on computer crime and served on a number of National Institute of Justice Technical Working Groups involved in the Forensic Sciences and Digital Evidence.  While residing in West Virginia, I was an Adjunct Professor at Fairmont State College.  While in England, I received my Master’s Diploma in Cybercrime Forensics from Canterbury Christ Church University in Canterbury, England.   More recently, I have served as an adjunct On-Line professor for the University of California at Irvine, and am still on faculty there.
