In this podcast episode, MRS Bulletin’s Laura Leay interviews Robert Hovden from the University of Michigan and his graduate student Jonathan Schwartz on development of the freely available tomviz platform (tomviz.org) that enables real-time three-dimensional (3D) visual analysis of materials. Building on the already existing tomviz platform, Schwartz created new algorithms capable of pulling data from transmission and scanning electron microscopes, evolving the 3D image as the experiment progresses. This research is published in a recent issue of Nature Communications (https://doi.org/10.1038/s41467-022-32046-0).
