Jan Schultheiss
About
Research statement. I am an early-career academic working on functional materials for energy applications. I combine my hands-on-expertise in processing (specialist in polycrystals) with advanced characterization. One of my key activities is ferroic domains and their interaction with microstructural degrees of freedoms, e.g., strain fields or grain boundaries, to develop sustainable materials for future capacitors, actuators, and caloric cooling devices. A Feodor-Lynen fellowship from Alexander-von-Humboldt society facilitated my transition from an independent researcher to the leader of a small research team and the elected deputy speaker in the German Physical Society. I guided larger collaborations with renowned groups from Berkley National Labs (US), ETH Zurich (CH), and the Tokyo Institute of Technology (JP). My international recognition is reflected by various awards, including Edward C. Henry Award (American Ceramic Society) and Electroceramics Young Researcher Award (Electroceramics Network).
