I’m a staff scientist at Caltech, working on the focal plane of NuSTAR, a hard x-ray telescope, set to be launched in 2012. Before NuSTAR, I worked on MegaSIMS, a mass spectrometer for the Genesis Mission, at UCLA.
I started using emacs as an undergrad in 1990 or 1991. I get sucked in deeper every year. So I guess this means that “I use Emacs.”
