Marwa Atwa
Postdoctoral Scholar, Photon Science, SLAC
BioMarwa Atwa is a postdoctoral scholar at Nanoscale Prototyping Laboratory (NPL), focusing on developing durable electrodes for hydrogen fuel cells. She got her Ph.D. in Chemistry from the University of Calgary in 2021 under the supervision of Professor Viola Birss, where she mastered different skills in both material science and electrochemistry fields. During her Ph.D. studies, she developed and tested highly active cathodes for hydrogen fuel cells based on novel nanoporous carbon films made from uniform and bimodal porous structures. Before joining the University of Calgary, Marwa received her M. Sc. And B. Sc. degrees in Chemistry from Suez Canal University, where her research focused on protecting low-carbon steel from corrosion in an acidic medium by applying various nanoengineered metal and alloys coatings using electroplating technique.

Igor Daniel de Araujo Evangelista
Postdoctoral Scholar, Photon Science, SLAC
BioDr. Evangelista's primary research focus lies in computational modeling and theoretical analysis of semiconductor materials using advanced quantum mechanical methods, including Density Functional Theory, Quantum Monte Carlo, and ab-initio Molecular Dynamics. Evangelista investigates the electronic, structural, and mechanical properties of materials, collaborating closely with experimental groups to bridge theoretical predictions with empirical results. He is also interested in the development of empirical potentials and enhancing materials modeling through the application of machine learning techniques.
Evangelista entered the Department of Materials Science and Engineering at the University of Delaware as a Ph.D. candidate in 2018, after completing an master degree in Physics 2016-2018 at Federal Fluminense University (Brazil). Recent work includes collaborations with experimental groups to bridge theoretical predictions with empirical results, as well as applying machine learning to creating of empirical potentials to accelerate materials modeling. Evangelista has also contributed to understanding electron mobility in metal-oxide semiconductors and strain effects in two-dimensional materials. These studies showcase his expertise in electronic structure and materials design for next-generation semiconductor technologies. -
Maitrayee Ghosh
Postdoctoral Scholar, Photon Science, SLAC
BioI am a postdoctoral scholar at the High Energy Density Sciences Division in the SLAC National Accelerator Laboratory in the Stanford University. I have received my PhD from the University of Rochester in 2023 in high-pressure chemistry. My research interests include theoretical and computational investigations of materials in both ambient and high-pressure regimes, that can be relevant for planetary sciences and inertial confinement fusion. I hail from Kolkata, India, and enjoy reading fictions and traveling in my leisure.

Sheikh Rubaiat Ul Haque
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 discovered light-induced terahertz parametric amplification and photonic time crystal state in excitonic insulator candidate Ta2NiSe5. He has also demonstrated efficient nonresonant nonlinear magnon generation in a Mott insulating Heisenberg antiferromagnet Sr2IrO4 as well as broadband optical control of plasmonic modes in semiconducting metamaterials.
Currently, Rubaiat is a postdoctoral scholar at Stanford University working on terahertz field-induced ultrafast dynamics in van der Waals antiferromagnets under the guidance of Professors Tony Heinz and Aaron Lindenberg. His research interests also broadly include cavity control and Floquet/Kapitza engineering of quantum materials. -
Sathya Narayanan Jagadeesan
Postdoctoral Scholar, Photon Science, SLAC
BioSathya Narayanan Jagadeesan is a postdoctoral scholar at the SLAC-Stanford Battery Center, with joint appointments in the Applied Energy Division at SLAC National Accelerator Laboratory and the Department of Materials Science and Engineering at Stanford University. He earned his Ph.D. in Chemical Engineering from Worcester Polytechnic Institute. His research focuses on earth-abundant and non-critical battery chemistries, including aqueous iron, sodium-sulfur, and sodium-ion systems, using advanced synchrotron X-ray characterization and data-driven approaches to understand interfacial chemistry and degradation mechanisms. His work aims to advance scalable and resilient energy storage technologies that reduce reliance on critical materials and strengthen the reliability of modern electric grids. He is driven by translating fundamental insights into practical solutions that support long-duration and widely deployable energy storage.

Jiarui Li
Postdoctoral Scholar, Photon Science, SLAC
BioI am currently a postdoctoral condensed matter experimentalist, material physicist, optical spectroscopist, and X-ray scatterer at Stanford University and SLAC National Lab. At Stanford, I work jointly with Harold Hwang and Wei-Sheng Lee on investigating the complex interplay between charge, spin, lattice, and orbital degrees of freedom in functional oxide quantum materials under extreme (strain) conditions. My expertise lies in the use of scattering, spectroscopy and imaging techniques to investigate materials, utilizing a range of photon sources from high-brightness X-rays generated at large synchrotron light sources, to lab laser source.
