I am a computer scientist working in the field of NLP and I received a bachelor's degree from Heinrich Heine University Düsseldorf in 2019 and continued to finish a master's degree in 2022 in Prof. Milica Gašić's dialogue systems and machine learning (DSML) group. Since the start of 2023 I am a PhD student in the DSML group with the topic of automatic dialogue ontology construction for task-oriented dialogue.
For any inquiries, feel free to reach out to me via mail!
