David Elsweiler

David Elsweiler is a Professor in the Department of Computer Science at the University of Regensburg's Faculty of Mathematics, Computer Science and Physics. With an extensive publication record spanning over two decades, he has established himself as a leading researcher in information retrieval, conversational search systems, and health/food recommender systems. His work bridges theoretical computer science with practical human-centered applications, particularly in domains requiring nuanced understanding of user behavior and credibility assessment.

Dr. Elsweiler's research primarily focuses on how people interact with information systems, with special emphasis on conversational interfaces, credibility assessment in search, and personalized recommendation technologies. His work in health informatics has led to innovative approaches for behavior change support through conversational agents, while his food recommendation research explores cross-cultural dietary preferences and nutritional considerations. He has made significant contributions to understanding how users verify information accuracy, particularly regarding controversial topics and health misinformation.

His recent publications reveal a strong trend toward leveraging large language models for behavior change applications, investigating how users blend traditional search with conversational interfaces, and developing methods to combat health misinformation. The work spans theoretical contributions to practical system implementations, with a consistent focus on real-world impact and user-centered design principles. His research often involves interdisciplinary collaboration with experts in health sciences, behavioral psychology, and nutrition.

Dr. Elsweiler has successfully supervised numerous doctoral students who have become active researchers in their own right, including Selina Meyer, Markus Bink, and Alexander Frummet. He has organized multiple workshops on health recommender systems at major conferences like RecSys, fostering community development in this specialized domain. His work has been supported by various research grants focused on improving information access in critical domains like healthcare and nutrition.
