Charlie Pritzlaff is a retired Air Force officer with over thirty-five years of experience in engineering development programs as both an engineer and program manager. His Air Force career included assignments as a satellite launch crew member (Titan IIIB/Titan IIID, four years); computer engineer for aircraft avionics development (EF-111A, three years); research and development manager for command, control, and display processing systems on headquarters staff (Strategic Air Command, three years), satellite planner and budgeter on the USAF headquarters staff (Pentagon, four years); and technical intelligence manager at Air Force Systems Command staff headquarters (Deputy Director, three years). After leaving the military, he spent three years at MILCOM Systems Corporation as program manager developing engineering models of mobile air traffic control systems for the Air Force; and thirteen years with MiTech, Incorporated as program manager for Federal Aviation Administration projects including air to ground data communications, remote maintenance monitoring systems, airport ground control radars, and electromagnetic interference detection systems. Charlie joined Georgetown University as Program Manager for the Fuel Cell Transit Bus Development Program in November 2005. He has a Master of Science Degree in Electrical Engineering (MSEE).

Don Mase is an experienced systems engineer who joined Georgetown's Advanced Vehicle program in 2000. Don provides technical oversight of all aspects of the Georgetown Fuel Cell Bus program, and he brings a strong knowledge of fuel cells, reformers, power electronics, hybrid electric vehicles, and systems engineering to the team. Prior to coming to GU, Don worked for two engineering consulting firms in the Washington, DC metro area on a variety of safety engineering projects, focusing on data acquisition and analysis as well as system design and testing. These projects included testing fire protection systems aboard Navy ships and surveying railroad tracks for freight and passenger rail systems across North America. Don also has previous hands-on experience with hybrid electric vehicles. His senior undergraduate project was the design and installation of sensors and controls for a car in the FutureCar Challenge, in which a Dodge Intrepid was converted to a series hybrid electric vehicle fueled by ethanol as part of a competition among 12 universities across the country. Don has a Bachelor of Science in Mechanical Engineering from the University of Maryland.

Sam Romano founded Georgetown University's Advanced Vehicle Development program. This program was initiated in 1983, and in 1994 produced the world's first Fuel Cell vehicle capable of operating on liquid fuel (methanol). The program has since developed two additional full size heavy-duty transit buses powered by Fuel Cells and operating on liquid fuel. The first of these vehicles is powered by a Phosphoric Acid Fuel Cell, and the other by a Proton Exchange Membrane Fuel Cell. These Fuel Cells have a net power output of 100 kW.

Sam has been involved in transportation, specifically electric vehicle research and development, for more than 30 years. His career and involvement with electric vehicles began in the 1960s with General Motors. There, in addition to developing advanced electric drives for the military and transit applications, he managed the Lunar Roving Program which produced the three electric vehicles used by Apollo 15, 16, and 17 astronauts for exploring extended areas of the moon. His efforts won him the NASA Public Service Medal in 1971.

After leaving General Motors, he became Vice President of MCR Technology where he was responsible for the design, development and production of battery-powered Mall buses for the city of Denver, CO. These buses have been in service since 1981. Following MCR, he was president of Technology Management, Inc. The company functioned as consultant to the transportation industry performing studies and analyses of new technologies for transit operations. He officially joined Georgetown University in 1987, having previously done consulting work.

Sam received his undergraduate degree in engineering and did graduate work at the New Jersey Institute of Technology.

Jim Larkins is a retired Air Force officer with over twenty-five years experience managing engineering development programs. His Air Force career included assignments ranging from crew member (B-52 bombardier, ten years), student (Air Force Institute of Technology, three years), Research and Development (Branch Chief, High Energy Laser Weapons, four years), and Headquarters staff (Strategic Air Command, Chief, Space Systems Division, two years). After leaving the military, he spent four years at Gould Ocean Systems Division developing electric propulsion systems for underwater vehicles, two years at Life Systems as Business Development Manager for Regenerative Fuel Cells for space applications, and seven years at Sundstrand Corporation in research activities for advanced power management and distribution technology for aircraft. He joined the Georgetown University Fuel Cell Transit Bus Development Program in March 1994. Jim has a Master of Science Degree in Electrical Engineering (MSEE) and a Master of Arts Degree in Business Administration.
