-My involvement in [projects](projects) often entailed collaboration with industry partners, where I delved into audio signal processing and honed my skills in training deep neural networks for analyzing sequences and image data. My final year presented a unique opportunity to investigate multi-agent reinforcement learning, focusing on safety and emergent phenomena within integrated industrial settings. This experience, combined with my personal interests, laid the groundwork for the [publications](publications) I've had the privilege to contribute to and the diverse skill set I've developed over time.

Additionally, my colleagues and I pursued what we affectionately termed as '*hobbies*', which led to my role as the lead organizer of the [open-source conference](https://openmunich.eu). My journey continued as I assumed responsibility for the editorial office of our [online magazine](https://digitaleweltmagazin.de/), further broadening my professional experience and introducing me to a variety of roles and tools beyond my initial expectations.
