Surjendu Bhattacharyya
Research Assoc-Experimental, 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. -

Accel System 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.

Olivier N. Bonin
Digital Media Specialist, SLAC National Accelerator Laboratory
BioBorn in the French Alps, I did a Master in Electrical and Micro-Electronic Engineering. I was an engineer in the Silicon Valley for 10 years developing semiconductor libraries of components for use on chips by many of the big names in the industry. After the last company I worked with was sold in parts, I left the industry to work on a full feature documentary about Burning Man. The film, Dust & Illusions, focused on a 30-year history that surprisingly nobody ever explored before. That lead me to develop video content for various companies, such as Whole Foods, Samsung, Stanford until I joined WildAid for a year producing videos to help stop the illegal wildlife trade (that potentially led to the covid-19 pandemic). Finally today I am the video and multimedia producer for SLAC National Accelerator Laboratory with the goal of bringing attention to the fundamental research in physics and biology that the Lab focuses on.

Sebastien Boutet
Senior Scientist, SLAC National Accelerator Laboratory
BioI am currently a Senior Staff Scientist at the Linac Coherent Light Source (LCLS), part of SLAC National Accelerator Laboratory. I also serve the role of LCLS Director of Experimental Operations since 2020.
I joined SLAC in 2007 working on the Coherent X-ray Imaging (CXI) instrument as part of the LCLS Ultrafast Science Instrument (LUSI) project. This project delivered one of the first operating LCLS instruments in 2011, available to the user community for cutting edge ultrafast x-ray science. After a few years of working with LCLS staff and a broad user community on many experiments, I also worked on the design and deployment of a new LCLS x-ray instrument, the Macromolecular Femtosecond Crystallography (MFX) instrument. From there, I became the Department Head for the LCLS Hard X-ray Department, charged with the operations of the XPP, XCS, MFX and CXI instruments. I worked in this role until 2020 when I become LCLS Director of Experimental Operations.
During my undergraduate studies in Physics at McGill University, I spent a summer at TRIUMF at the University of British Columbia working on heavy ion cooling trap simulations. After graduating with Honours in 1999, I joined Ian Robinson x-ray diffraction group at the University of Illinois at Urbana-Champaign, where I learned how to perform synchrotron experiments at multiple light source including NSLS, ESRF and the APS. My primary focus during PhD work was on applying known and novel techniques of surface diffraction and coherent diffractive imaging to the study of protein crystals. After some work on large protein crystals surface diffraction at NSLS, most of my efforts shifted to a new beamline at the APS. I participated in the installation and commissioning of this beamline, sector 34ID-C, although I was far from the primary contributor. This nevertheless introduced me to the intricacies of building x-ray beamlines. I then used this beamline for a few years to study the shapes and internal defects of crystals of proteins using newly developed coherent diffractive imaging techniques applied to small crystals. While some successes were achieved, it became clear that limitations exist at synchrotrons due to sample motion and radiation damage. Luckily, as I completed my PhD work in 2005, new light sources were in construction that would remove thee limitations. FLASH in Hamburg and LCLS were soon to come online. I spent a few years at the APS trying to observe shape transforms from protein crystals, with great difficulty, something that LCLS now routinely accomplishes without much effort due to the instantaneous nature of the LCLS measurements.
After completion of my PhD work, I joined SLAC as a Research Associate, with a joint appointment with Uppsala University and Janos Hajdu but spending all my time at Lawrence Livermore National Laboratory working with the group of Henry Chapman. We spent a couple of years using FLASH to demonstrate the feasibility of using ultrashort FEL pulses for “diffraction-before-destruction” imaging and developing new tools and techniques for FEL research. -

Cameron Bravo
Casual - Nonexempt, SLAC National Accelerator Laboratory
BioBorn in Kansas City, Missouri and attended high school in Peculiar (Ray-Pec). Undergraduate studies at the University of Nebraska - Lincoln, the Paul Scherrer Institute, and the Swiss Federal Institute of Technology (ETH Zurich). Studied ASIC design after helping characterize the PSI46 pixel chip used in the CMS detector. Graduate education at UCLA searching for Electroweak Sphalerons in proton-proton collisions with the CMS experiment while working on the muon system. Wrote BaryoGEN, a new Monte Carlo generator, to study all possible B+L violating fermion configurations potentially generated via Sphalerons and/or Instantons. Interests include front-end detector electronics, DAQ systems, gas detectors, Si detectors, non-perturbative physics (especially within the Standard Model), High-Multiplicity Electroweak Boson production, and exotic dark matter models. Currently working with the Heavy Photon Search (HPS) experiment on the Silicon Vertex Tracker (SVT) sub-system and searching dark sector models with an A' lighter than the dark matter threshold, SIMPs, and true muonium.

Brendon A Bullard
Research Assoc-Experimental, SLAC National Accelerator Laboratory
BioI am a postdoc in the SLAC ATLAS group working on measurements of top quarks and searches for Di-Higgs production. I am also working on the data acquisition system for the ITk pixel detector upgrade and feasibility studies for the Cool Copper Collider concept. Aside from my research interests, I am an active member of the SLAC outreach community - please do not hesitate to get in touch by email, especially if you are a student.
