Dr. St. Germain has managed and supported a wide range of space systems and architecture design activities for SpaceWorks Enterprises, Inc. (SEI) government and commercial clients. He has a strong background in aerospace systems design, with specific disciplinary expertise in space vehicle trajectory simulation, weight estimation and propulsion analysis.
As director of SpaceWorks Engineering’s Advanced Concepts Group (ACG), Dr. St. Germain is directly involved in all engineering projects conducted by the ACG. Recent activities that Dr. St. Germain has either led or supported include an AFRL study of Reusable Booster Systems (RBS), an examination and prioritization of horizontal launch system concepts, the design of a commercial nano-satellite launch platform, and a technology assessment activity for a Two Stage to Orbit (TSTO) Turbine-Based Combined Cycle (TBCC) launch vehicle. Other past work while at SEI includes the design of various lunar exploration architecture concepts, the evaluation of a small payload class Earth-to-Orbit launch vehicle, investigation of a Nuclear Electric Propulsion (NEP) powered Pluto/Kuiper Belt exploration mission, and the development of both an in-space trajectory analysis tool and a parametric space vehicle weight estimation tool. Dr. St. Germain also leads many of the technology assessment activities conducted at SEI.
While at the Space Systems Design Lab at the Georgia Institute of Technology, he developed an optimization technique for the performance and powerhead configuration of liquid rocket engines (Ph.D. Thesis), led various conceptual level launch vehicle and space systems design projects, and supported other research projects with propulsion/trajectory/weights & sizing analysis. Dr. St. Germain also has work experience obtained through positions at Pratt & Whitney Space Propulsion, NASA Marshall Space Flight Center, and NASA Langley Research Center.
Dr. St. Germain holds Doctoral and Master’s Degrees in Aerospace Engineering from the Georgia Institute of Technology, along with a minor in Mathematics. He also holds a Bachelor of Science degree in Mechanical Engineering from Louisiana State University. Dr. St. Germain is a member of the American Institute of Aeronautics and Astronautics and the AIAA Space Transportation Technical Committee (STTC).
