About me

I'm a physicist with a real passion for x-ray FELs. I earned my PhD from Northern Illinois University (NIU). My research has covered x-ray optics, FELs, nonlinear physics, beam dynamics, and computational physics.

Right now I'm a scientist at SLAC National Accelerator Laboratory and Stanford University, where I work on developing new cavity-based x-ray sources. Outside of physics, I enjoy stargazing, XC skiing and sim racing.
