Bio: Stephanie (Steph) Ribet graduated from Princeton University with a degree in chemistry and a minor in materials science in 2016. She worked as a chemist at Dyson/Sakti3 from 2016 to 2018 on solid-state battery development. She completed her Ph.D. in the Department of Materials Science & Engineering at Northwestern University with Vinayak Dravid in 2023. At Northwestern, she designed nanocomposite sponges and characterized these structures at multiple length scales with microscopy and spectroscopy techniques. In the final year of her graduate work, Stephanie joined the Molecular Foundry as an Office of Science Graduate Student Research Program Fellow to develop scanning transmission electron microscopy methods for soft and hybrid materials. Building on this research, she continued at Berkeley Lab as a postdoc working with Colin Ophus and Karen Bustillo on the experimental and computational development of multidimensional high-resolution electron microscopy methods. She began as a Staff Scientist at the Molecular Foundry in 2025.

Bio: Nicholas Hagopian received a Bachelor of Chemical Engineering and Bachelor of Science in Chemistry from the University of Minnesota in 2021. Hagopian completed his Ph.D. in the Department of Materials Science and Engineering at the University of Wisconsin Madison with Paul Voyles in 2026. His graduate research focused on high resolution STEM characterization and STEM technique development applied across a variety of materials systems including 2D transition metal dichalcogenides, Heusler alloy membranes, superconducting materials/devices for quantum computing, light emitting diodes, and metal/precipitate systems. In his final year he conducted research at LLNL and LBNL through the DOE SCGSR and Molecular Foundry (MF) user proposal programs. Hagopian joined the LBNL MF as a postdoctoral researcher in 2026. His research will continue to pursue STEM technique development towards materials characterization.
