About
During my studies at Johannes Kepler University Linz, I worked as a student research assistant at the Institute of Computational Perception. My research focused on Recommender Systems - initially on mitigating inherent biases, and later on leveraging multimodal side information to address cold-start and missing-modality scenarios. My work has been published in renowed conferences and journals, including SIGIR, RecSys, and TORS.
In addition, I contributed to EmoMTB, a science communication project presented at the Ars Electronica Festival, with which we showcased an interactive music exploration interface.
