Justin Pontius, Research Specialist

Justin Pontius, Research Specialist, joined the NMR team at Notre Dame in 2011. His major responsibilities include maintenance of all NMR systems, user familiarization and training. He has a wide range of experience in communication systems that utilize radar and digital radio technology.

Justin joined the US Navy in 2000 and was trained as an Electronics Technician, specializing in radar and communications at the Great Lakes Naval Training Center.  After graduation in 2001, he was assigned to the guided missile destroyer USS John S. McCain (DDG-56), where he maintained all shipboard external communication systems, radars, and TV/radio systems.  In 2005, Justin was reassigned to Tactical Training Group Pacific in San Diego, Calif., and led a team of nine personnel installing and maintaining analog and digital radio systems that linked San Diego, Washington, Hawaii, and Japan.  In 2007, he was sent to a forward operation base in Ethiopia to provide communications for a remote Seabee team building schools and digging wells during Operation Enduring Freedom.  He also provided onboard satellite communications for the Marine Heavy Helicopter Squadron 461, flying in CH-53E Super Stallion helicopters.  In early 2008, Justin left the navy to start a career with JEOL USA Inc.  There he installed, maintained and troubleshot all variants JEOL NMR systems.
