About me

I started my bachelor's degree in chemical and process engineering at Graz University of Technology in October 2016, graduating in November 2020. During this study I also had the opportunity to spend a semester abroad at the University of Strathclyde in Glasgow, Scotland.

Subsequently, I also studied for a master's degree in chemical and process engineering and specialized in the field of plant and process engineering. During this master's program, which I completed with honors in March 2023, I developed a special interest in numerical simulation tools for solving engineering problems. I was also able to apply these simulation tools in a project involving the CFD simulation of a room fumigation with hydrogen peroxide to ensure clean room conditions.

Since May 2023 I am employed as a university assistant at the Institute of Process and Particle Engineering and I have started my PhD studies in technical sciences.

Research interests

Currently I am working on the project "Ni2Steel" which aims to make the recycling process of NiMH batteries more controlled and environmentally friendly. This would allow the batteries to be used as a secondary raw material in the steel industry, for example. The challenge is that the recycling process is confronted with safety-related problems, such as an increased risk of fire due to material heating.

In order to make the recycling process safer, certain material properties (e.g. the tensile strength) of the crushed NiMH batteries are determined experimentally at TU Graz. My goal is to use the obtained data to generate simulation parameters for the discrete element method (DEM). This allows us to realistically represent the flow and thermal conduction properties of the crushed batteries. AI-supported models are also to be used for the efficient and quick determination of the appropriate parameters for the simulation. It is thus possible, for example, to use DEM simulations to simulate the material transport in a screw conveyor.
