Satoko Toyama received her Ph.D. in Engineering from the University of Tokyo in 2023, under the supervision of Prof. Yuichi Ikuhara and Prof. Naoya Shibata. She held a JSPS research fellowship for young scientists (DC1) from 2020 to 2023. After completing her Ph.D., she joined the Institute of Engineering Innovation at the University of Tokyo as a Project Assistant Professor from 2023 to 2024. Since April 2024, she has held the position of Assistant Professor, and as of October 2024, she also served as a JST PRESTO researcher. Her research focuses on imaging electromagnetic fields using differential phase contrast scanning transmission electron microscopy (DPC STEM), including the development of a tilt-scan averaged DPC STEM technique [S. Toyama et al., Ultramicroscopy 2022], quantitative, nanometer-scale mapping of two-dimensional electron gas at gallium nitride semiconductor heterointerfaces [S. Toyama et al., Nature Nanotechnology 2023], and the observation of space charge layers at yttria-stabilized zirconia grain boundaries [S. Toyama et al., Nature Communications 2024].
