– supplemental travel support for group

ending approximately $30K annually– supplemental manpower support

decreases from 2 ½ research scientist positions and ½ postdoctoral fellow to

½ research scientist position and ½ postdoctoral fellow in 2008• Recent support

– renovation / construction of GEM test lab for group at a cost ~$200K (in 2003-4)– appointed D. Kharzeev Adjunct Professor (2007)
