About Us


Congratulations to Dr. Bernstein!
by stohrgroup, May 16, 2012
David defended his thesis this spring with aplomb. We think it was the tastiest defense yet, with homemade treats made by Nicole! David is moving on this summer to become a patent agent at a bay area firm - we better keep his email handy...

Congratulations to Dr. Burkhardt!

Mid summer party at Jo's house
by stohrgroup, Aug. 15, 2009
For the past three years, Dave have been hosting our group summer parties with the theme of "good food, good life". We enjoy greens from his backyard and the happy cow delivered from the Morris farm. This time, Jo is taking us 40 years back, when he first travelled across the atlantic, to see how 3 days of peace and music have changed the world.

peace, particle trace, and speckle.

Concert and Remembrance in Celebration of the Life of Hans-Christoph Siegman
by stohrgroup, Jul. 29, 2009

Prof. Stöhr to become SLAC lab associate director of LCLS
by SLAC Today, Jun. 3, 2009
Effective July 1, Jo Stöhr will take over from Dale Knutson as the new director of LCLS. Jo came to SLAC in 2000 and has been director of the Stanford Synchrotron Radiation Lightsource since 2005. Jo has been co-leading the joint light source efforts with Lawrence Berkeley National Laboratory for the past year. He now will bring his experience and broad expertise in light source science to LCLS.
