Project Scientist, SLAC National Accelerator Laboratory
BioI am currently a Research Associate at SLAC’s LCLS SRD Chemical Science Department. My research focuses on time-resolved dynamics in the gas phase, with a particular interest employing novel experimental techniques to investigate the dynamics of molecules, radicals, and ions. These techniques include Coulomb explosion imaging, MeV electron diffraction (MeV-UED), X-ray scattering, X-ray absorption, and photoelectron spectroscopy. This work aims to improve the fundamental understanding of energy, environmental, biological, and atmospheric processes.
I am currently adapting a pyrolysis source to a time-of-flight spectrometer to perform time-resolved studies of radicals using UV, high harmonic generation (HHG), and X-rays. Additionally, I plan to integrate the pyrolysis setup with MeV-UED to investigate structural molecular dynamics through diffraction measurements. -

Accelerator Systems Operator I, SLAC National Accelerator Laboratory
BioI am a 2022 graduate with a B.S. in physics from the University of Maryland at College Park, and I currently operate the world's longest and most powerful linear particle accelerator administrated by Stanford University under the direction of the US Department of Energy. Here I interface directly with the machinery, controls, and safety systems for three linear accelerator facilities: FACET-II where electron-pair beams are shot thru hot plasma to study novel wakefield acceleration techniques, LCLS where coherent x-rays of very high energy (and inversely low wavelength) probe deep into matter for imaging at atomic scales, and LCLS-II where commissioning is underway to produce a much more powerful megahertz rep rate superconducting beam that can leverage the same XFEL mechanism to (instead of just taking snapshots) also resolve the dynamics of chemical reactions in situ.
