About the person
After graduating from HTBLuVA in St. Pölten in 2002, Harald Özelt began his career as an electrical engineer in project management. In search of new challenges, he began his studies at the St. Pölten University of Applied Sciences in 2007. He received his Bachelor degree with distinction in Communication & Simulation Engineering in 2010 and his Master degree with distinction in Industrial Simulation 2012. The research topic of the Master thesis was the characterization of NdFeB permanent magnets, where new software tools for the simulation and optimization of permanent magnets were developed. During his studies he worked in the research team of Thomas Schrefl at the St. Pölten University of Applied Sciences from 2010 on finite element models and simulations of magnetic materials. In 2015, he moved to the Center for Modeling and Simulation at the Department for Integrated Sensor Systems at the Danube University Krems in Wr. Neustadt, where he focused on simulations of magnetic materials for heat-assisted magnetic recording and rare-earth efficient permanent magnets. In 2019, he received his PhD in technical sciences (Dr. techn.) with distinction from the Vienna University of Technology. The topic of his dissertation was the micromagnetic simulation of exchange-coupled ferric/ferromagnetic composites. Since then he has been working as a postdoctoral researcher on stochastic micromagnetic simulations and the effect of interfaces on magnetization reversal.
