I retired from NASA Ames Research Center in Jan 2018, so my NASA email address is no longer active,
and my NASA wepage and publications page have not been updated since then.
I have scaled back on my professional activities, but am still doing some consulting work with NASA, and
with Arizona State University (ASU). I am also remaining active with AAAI and ICAPS for the forseeable future.
You can contact me at the following email address:
