I have retired from NASA with 36 year of service as of April 2019. Currently I'm with Booz-Allen-Hamilton supporting the NASA Gateway Program Office with early program formulation and requirement definitions.In early years, I was involved in many aspect of engineering, from designing a guidance algorithm for Shuttle to Station glideslope approach, to writing code and building sims to analyze ISS altitude maintenance and reboost strategy, to lab and field testing the NASA X38 Crew Rescue Vehicles, to name a few. In mid career, I joined the International Space Station (ISS) Program as the Element Manager for the JAXA HII-Transfer Vehicle (HTV), responsible for the integration of its first three successful flights to the ISS. The HTV continued to deliver critical supplies and payloads to the ISS today. During the later part of my career, I served as Manager of the International Partner (IP) Element and Visiting Vehicle Integration Office then as Manager of the Commercial Crew Integration Office. During my time as office manager, I also served as a key member of the NASA team that developed a new and innovative approach to procure commercial services for crew transportation to the ISS. Today, in 2018, we are on the verge of seeing test flights to the ISS for both commercial providers, Boeing and SpaceX. Currently, I serve as the Commercial Crew Program liaison to the ISSP, their IP, and the FAA. For the IP, my role is to get them comfortable that the US Commercial Vehicles will be safe for their astronauts to ride. It is a challenging endeavor, balancing between sharing information they would need to know to concur vs. limitations of data rights and export control restrictions . For my role with the FAA is to collaborate and seek commonality in requirements and process efficiencies for seamless transition from flight tests under the Government authority to commercial missions under the FAA authority for public safety.
