Our group continues to grow, and we are delighted to welcome Soumik Bhattacharjee, who joined us as a PhD student on February 1, 2026.

Soumik holds a Bachelor’s degree in Computer Engineering from Manipal International University in Malaysia, where he graduated on the Dean’s List. His bachelor’s thesis on multichannel quartz crystal sensors received two IEEE Local Chapter awards. After nearly two years of industry experience as a web developer, he pursued a Master’s degree in Digital Media with a specialization in Media Informatics at the University of Bremen.

During his master's studies, Soumik worked as a student assistant at the Leibniz Centre for Tropical Marine Research (ZMT), where he developed agent-based simulation models for complex ecological systems. He also contributed to the DFG-funded ComAI project at the Digital Media Lab Bremen, where he helped build a RAG-based chatbot for university students. Additionally, he completed a semester abroad at Université Paris-Saclay through the Erasmus Mobility Program. In his Master’s thesis, titled “Designing Conversational Agents for Multilingual Realities: A Study of Code-Mixing and Cultural Adaptivity”, Soumik investigated how individuals from diverse cultural and linguistic backgrounds perceive, experience, and expect conversational agents to handle code-mixed communication.

Soumik’s research interests center on the human-centered design of conversational user interfaces, with a particular focus on multilingual, culturally adaptive, and socially aware interaction. As part of the Human-AI Interaction group, he will explore how multimodal and embodied agents can better support natural communication across languages and cultures, combining insights from HCI, computational linguistics, and social computing.

In his doctoral research, Soumik plans to investigate how conversational agents can adapt dynamically to users’ linguistic practices, cultural contexts, and situational cues. Building on the “Computers Are Social Actors” paradigm, his work aims to contribute to the development of agents that are not only technically capable but also socially intelligent, trustworthy, and sensitive to human expectations. Through this work, he seeks to bridge human and artificial communication in ways that feel intuitive, inclusive, and meaningful.

We are excited to have Soumik join our team and look forward to his contributions to our research and community. Welcome to the group, Soumik!
