Hendrik Ohldag
http://www.stanford.edu/~hohldag, Staff Scientist of SSRL
In charge of the brand new STXM beamline at SSRL BL13-1. The instrument is currently being commissioned. Hendrik is also the daddy to two Aussie cattle dogs, JoJo and Jolanda.

Post-docs
Alexander Reid
alexhmr@slac.stanford.edu, Research Associate
Alex finished his D.Pill at University of Oxford and then spent two years as a postdoc in the Radboud University of Nijmegen before joining the Stöhr group. Alex's research is focused on measuring and controlling magnetism dynamics in oxides and metals. A native a Ireland, he enjoys a bit of craic when not at the lab...

Alexander Gray
axgray@slac.stanford.edu, Research Associate
Alex's research interests include ultrafast nanoscale electron and spin dynamics, and the development of new x-ray photoemission techniques for studies of buried layers and interfaces.

Stefano Bonetti
bonetti@slac.stanford.edu, Research Associate
Stefano got his Ph.D. with a thesis on spin waves dynamics at the KTH - Royal Institute of Technology, Stockholm, Sweden. He joined the group in March 2012 as a postdoctoral fellow, and he is currently attempting to combine time resolved measurements and direct spatial imaging of spin waves using x-rays.

Graduate Students
Roopali Kukreja
roopalik@stanford.edu, Graduate Student in Material Science and Engineering
Went to college at the renowned I.I.T. in Bombay (why is it called Mumbai now?), she joined the group in the spring of 2009. Roopali has focused on studying ultrafast electronic and lattice responses of magnetite following laser excitation.

Tianhan Wang
wangth@stanford.edu, Graduate Student in Material Science and Engineering
The second U. Mich. boy in our group, Han and Bill ceratinly team up during football season... Go Blue! Han's work now focuses on the use of coherent x-ray scattering to study the properties of next-generation granular magnetic media, while also working on different x-ray imaging techniques at LCLS and SSRL.

Cat Graves
cgraves@stanford.edu, Graduate Student in Applied Physics
Cat graduated from Georgetown University, majoring in Physics and Political Science. Once she joined the group in summer 2009, she hit the ground running with the design and building of the RCI endstation. Her main work now focuses on the use of x-rays to illuminate the nanoscale transfer of angular momentum during ultrafast processes in magnetic materials.

TianMin Liu
tianminl@stanford.edu, Graduate Student in Physics
TianMin joined the group in 2012, and is quickly becoming an expert in fourier transforms!

Patrick Granitzka
pagranit@slac.stanford.edu, Graduate Student in Physics
Joining us through the University of Amsterdam in early 2013, Patrick is our new laser expert, having spent his diploma research project with the Aeschlimann group at the University of Kaiserslautern, Germany and the Kapteyn-Murnane group at JILA, University of Colorado at Boulder.
Can you guess where Patrick is?
Markus Hantschmann
markush@slac.stanford.edu, Graduate Student in Physics
Joining us from TU Berlin in early 2013, Markus will mainly work on LCLS projects, although we hope to leverage his FIB and MFM experience for our SSRL projects when he has spare time!
Joe Chen
zchen89@gmail.com , Graduate Student in Physics
Joe is our newest graduate student who joined the group in 2013. Before coming to SLAC, he worked on various tabletop AMO projects, but he is eager to extend his experience into the exciting world of ultrafast x-rays at SSRL and LCLS!
He is also known to occasionally make corny pew pew sound effects when shooting a laser. Doctors are still searching for a cure.
Hunger strikes when not at beamtime!
Zhang Zhang
zhangzhang3x7@gmail.com , Graduate Student in Physics
Zhang is rotating with us, and has quickly learned the ins and outs of LCLS data analysis! Along with Joe, he has already participated in low alpha beamtimes galore.
Close Collaborators
Kathryn A. Moler
Research Group Website, Professor of Applied Physics, and of Physics, Stanford University
Our work with the Moler group seeks to leverage our two very different magnetic imaging schemes: SQUID and x-rays.
