BACKGROUND:
I joined the SSG in June of 2004, and I am assigned to Beamline
8.0. I have previous work experience at LBL in the Physical
Biosciences and the Energy and Environment Divisions. Also,
in 1989, I was a visiting scientist at the Paul Scherrer Institut
in Switzerland, where we studied electrode surfaces. Much
of my previous research has involved the development of mechanical,
electronic, and optical instrumentation.
Please
email me with any comments or inquiries.
