Bio

I joined the Planning and Scheduling Group at Ames in late 2007. My current project is the Emergency Landing Planner for Damaged Aircraft, led by David Smith. Recently, I was a development manager for the SACE and ConFRM projects, two collaborations between our group and teams in the Mission Operations Directorate at JSC. I participate when possible in the EUROPA development team, and enjoyed a chance to play with footfall planning for the ATHLETE robot a few years ago.

I came to Ames from Oregon, where I had a great time at On Time Systems, Inc. (OTS) developing optimization algorithms for large industrial problems. While there, I was able to complete a Ph. D. in Computer and Information Sciences next door at the University of Oregon.

In my distant past, I graduated with a B.A. in Mathematics from Williams College in 1998 and spent the following two years teaching math at the Casablanca American School before heading to Eugene. My family and I now live in Bellingham, Washington; I telecommute from home, and travel regularly to Ames to collaborate with my teams.
