Personal profile
Research interests
Within the scope of national and international projects, I work as Research Engineer in the research field "Efficiency in Industrial Processes and Systems" at the Center for Energy of the AIT Austrian Institute of Technology since 2021 on the decarbonization of industry.
My focus is on the technological development and numerical simulation of industrial high-temperature heat pumps, including for the generation and supply of steam, as well as their practical integration in production processes and plants, including the planning and implementation of measurement campaigns and following data analysis.
I studied mechanical engineering and management at Vienna University of Technology, acquired skills in the fields of mechatronics and computer science in various internships, and developed an algorithm for assistance systems in mobile machines based on machine learning in the course of my diploma thesis.
