The Hub of Computing and Data Science (HCDS) at the University of Hamburg is pleased to welcome two international visiting researchers: Tadesse Belay and Subhankar Swain. During their research stays, they will contribute to the interdisciplinary work at HCDS in the fields of Natural Language Processing (NLP), AI safety, and digital society.

Research on AI, Language, and Safety

Tadesse Belay is a PhD candidate in Computer Science at the Computing Research Center of the National Polytechnic Institute in Mexico. His research focuses on Affective Computing, Large Language Models (LLMs), NLP methods for low-resource languages, and cross-cultural AI safety analysis.

At HCDS, he collaborates with researchers working on NLP and AI safety, contributing to ongoing research on language-based AI systems and their societal implications.

Multimodal Harmful Content Detection

Subhankar Swain is a PhD research scholar at the Indian Institute of Technology (IIT) Kharagpur, where he works under the supervision of Prof. Animesh Mukherjee on multimodal harmful content detection. During his stay in Hamburg, he collaborates with Prof. Chris Biemann, Dr. Seid Muhie Yimam, and Robert Geislinger on extending HatePRISM, a framework for multilingual and multimodal harmful content analysis.

International Collaboration at HCDS

The visits of Tadesse Belay and Subhankar Swain highlight the importance of international scientific collaboration at HCDS. Bringing together diverse perspectives, methodologies, and research contexts strengthens ongoing work on globally relevant topics such as AI safety, language technologies, and responsible artificial intelligence.

HCDS is delighted to host both researchers and warmly welcomes them to Hamburg.
