David Muller, Director of the PARADIM Electron Microscopy Facility at Cornell University, has received the 2021 Ernst Ruska Prize from the German Society for Electron Microscopy (DGE). This prestigious award recognizes his groundbreaking contributions to ultrahigh-resolution electron microscopy and electron spectroscopy, notably advancing lens-less imaging techniques into the deep sub-Ångström range beyond traditional aberration-corrected methods.
