Ivan A. Moreno-Hernandez

Assistant Professor of Chemistry

The Moreno-Hernandez lab is a multidisciplinary group focused on understanding electrochemical materials to advance renewable energy technologies and create a sustainable future. Their primary tool is liquid cell transmission electron microscopy, a technique that enables direct observations of the structural dynamics of materials in real time and at near-atomic resolution in a realistic liquid environment. They complement this technique with a wide set of analytical techniques and materials synthesis methods that enable the characterization and synthesis of materials with nanoscale precision. This combination enables systematic studies of the relationship between nanoscale structure and macroscale properties. In addition to their research efforts, the Moreno-Hernandez lab aims to create an inclusive environment that embraces the lived experiences of each group member and provides support for ongoing personal growth.
