Your backgrounds?

[bluesbassman]

I have B.S. and M.S. degrees from Virginia Tech, and a Ph.D. from The University of Texas at Austin, all in aerospace engineering. The general research area for my Ph.D. was control theory.

These days I work for an aerospace company designing attitude control systems for spacecraft.

Yes, as my 2p2 name suggests, I also play bass guitar in local blues bands.
