Experience

• NASA Glenn Research Center

  Aerospace Engineer/Research Scientist

  Specific research; microgravity capillary phenomena: capillary flows induced by discontinuously wetted surfaces, interface (static free surface) uniqueness and stability, interface dynamics and damping, moving contact line, wetting, spreading, and contact angle measurement, capillary driven flows due to container geometry. Experimental research conducted in NASA drop towers, low-g aircraft, and aboard Space Shuttles (ICE-1, ICE-2, DYLCO) and the Russian Mir Space Station (ICE-Mir, ALB).

• Portland State University

  Professor

  Department of Mechanical and Materials Engineering: research interests include macroscale and microscale capillary-driven flows in complex geometries, passive cooling systems, microscale thermal devices, and microgravity fluid mechanics with experimental verification using drop towers and the International Space Station (CFE-1, CFE-2, CCF). Teaching emphasis centers on thermal/fluids sciences and often contains a public interest or k-12 educational aspect, including low-g aircraft, drop tower, and high altitude ‘BalloonSat’ student teams.

• TDA Research

  Sr. Aerospace Engineer

  Conducted applied research in aerospace technologies relating to fuels and coolant management in spacecraft, passive thermal transport systems including the non-capillary Pulse Thermal Loop (PTL), lightweight freeze tolerant, MMOD safe, carbon composite radiators, ejector systems.
