Felix Allum
Postdoctoral Scholar, Photon Science, SLAC
BioI am a Postdoctoral Scholar affiliated with the PULSE institute and the LCLS Laser Science Division. My research interests focus on the ultrafast photodynamics of isolated molecules in the gas phase, as studied by a range of techniques typically incorporating charged particle imaging, photoionization spectroscopy or diffractive imaging. I am also interested in developing new approaches to studying ultrafast photochemistry, through, for instance, the generation of broad bandwidth optical pulses and new data analysis techniques to extract additional information from rich and complex datasets.
Prior to joining SLAC in October 2021, I studied for my PhD at the University of Oxford under the supervision of Mark Brouard. My doctoral research included a range of studies into ultrafast photodissociation dynamics using velocity-map imaging, both in a laboratory setting and at international FEL facilities. -

Filippo Balzaretti
Postdoctoral Scholar, Photon Science, SLAC
BioI like to define myself as an aspiring 360° scientist. What does that mean? Well, that it is a strong wish of mine to collect as much knowledge as possible in what are (at least in my opinion) the three main fields of science: Mathematics, Physics and Chemistry.
This is why, after having received my Master in Mathematics at the University of Turin, Italy, I worked as a Ph.D. student in Physics at the University of Bremen, Germany. Recently I've been hired from the University of Stanford to proceed my academic path with a Post-doc position at the SUNCAT Center for Interface Science and Catalysis.
I will put all my efforts to provide the scientific community with important insights and discoveries. -

Postdoctoral Scholar, Photon Science, SLAC
BioRubaiat received his undergraduate degree in Applied Physics from the University of Tokyo in 2017. He then moved to the University of California San Diego where he finished his PhD in Physics under Professor Richard Averitt in 2023. During his PhD, he performed time-resolved broadband terahertz spectroscopy on excitonic insulator candidate Ta2NiSe5 where he demonstrated light-induced terahertz parametric amplification and photonic time crystal state mediated by phonon squeezing. He has also worked on the optical control of plasmonic modes in semiconducting metamaterials. Currently, Rubaiat is a postdoctoral scholar at Stanford University working with Professors Tony Heinz and Aaron Lindenberg on the strong-field lightwave-driven dynamics and nonlinear magnonics in low-dimensional materials.

Laura Pereira Sanchez
Postdoctoral Scholar, Particle Physics and Astrophysics, SLAC National Accelerator Laboratory
BioThe composition of the Universe and the interplay of its various forces and matter have always fascinated me. My journey into particle physics began when I joined the ATLAS Collaboration during master's. Since then, I have analyzed data from proton-proton collisions at the Large Hadron Collider (LHC), where I've been looking for novel particles and deviations from theoretical predictions. At Stanford, I study the shape of the Higgs potential. I apply state-of-the-art machine learning techniques to measure the production of Higgs boson pairs using data from the ongoing LHC run and study if the shape of the Higgs potential differs considerably from that predicted by the Standard Model (SM). Furthermore, I work on the upgrade of the ATLAS inner-tracking detector for the future High Luminosity LHC (HL-LHC), which will be crucial to study the Higgs potential if its shape aligns with the SM predictions.

BioMy current research focuses on the design of catalytic materials. I have studied atomistic phenomena on catalytic surfaces to develop materials with improved catalytic capability under the philosophy of rational design. To achieve this goal, I use computational approaches, e.g., first-principles calculations and artificial intelligence (AI). Applications include heterogeneous catalysis for exhaust emission control, hydrogen production, and utilization of emission gas to realize carbon neutralization.

MANUEL RAFAEL VEJAR
Postdoctoral Scholar, Photon Science, SLAC
BioManuel (Manny) Vejar is a postdoctoral scholar at SLAC National Accelerator Laboratory, specializing in synchrotron imaging and spectroscopy at the Stanford Synchrotron Radiation Lightsource.
He received his Ph.D. in the Civil & Environmental Engineering & Earth Sciences department at the University of Notre Dame in 2024. His Ph.D. work focused on the impacts of iron-oxide mineral complexity on the fate and transport in nuclear waste repository and/or legacy environmental contamination settings. Specifically, he studied the influence of Al-substitution in iron (oxyhydr)oxide minerals on the redox and speciation behavior of plutonium at the mineral-water interface, employing M4-edge HERFD-XANES to determine the oxidation state and L3-edge EXAFS to determine coordination environment of the plutonium associated with these minerals.
He has over 7 years of experience with synchrotron techniques (microXRF imaging, XANES, and EXAFS), and their applications to study contaminants in environmental systems. During his career, Manny has conducted work at the Stanford Synchrotron Radiation Lightsource, the Advanced Photon Source, and the European Synchrotron Radiation Facility, collaborating with Chapman University, and the Institute of Resource Ecology at the Helmholtz-Zentrum Dresden-Rossendorf.
