Dr. Erik Weiser is the acting deputy assistant administrator for NASA’s Office of Strategic Infrastructure (OSI). He supports the assistant administrator of OSI with operational management and oversight of the office, ensuring that NASA can meet mission requirements while maintaining affordability, efficiency, and sustainability.  

As part of the Mission Support Directorate, OSI includes the Environmental Management Division, the Facilities and Real Estate Division, the Logistics Management Division, and the Space Environment Testing Management Office. Each branch works together, across NASA’s centers, to manage the agency’s wide-ranging portfolio of infrastructure, assets, and capabilities.  

Weiser leads the budget formulation and execution for Infrastructure and Technical Capabilities, and Construction, Environmental Compliance, and Restoration. He assists in streamlining the office’s acquisition processes and provides objective evidence of OSI’s program performance. Weiser also continues to advance the Agency Master Plan, an initiative he led during his time as director of the Facilities and Real Estate Division. The Agency Master Plan is a cohesive, comprehensive, and integrated plan to make sure NASA’s infrastructure remains sustainable and resilient.
