I work for NASA at the Marshall Spaceflight Center in Huntsville, Alabama.  Currently the big project is Ares I, where we're quantifying and qualifying all failure modes, big and small.  By understanding how complex systems malfunction, we can design smarter sensors and react and recover from failures more effectively.  It also means, in the event of a catastrophic failure, being able to detect the problem before it's too late.

Before the Constellation program, I worked at Penn State as a grad student doing similar things, plus astrodynamics, autonomous robotics and machine learning and AI type stuff. Even farther back in ancient history, I did systems engineering at Johnson Space Center, where I worked X-38 and Shuttle flights to ISS.
