Hi there, I'm Thiemo.

I am a tenure-track Research Assistant Professor for Digital Technology Management and lead of the Human-Centered AI-based Systems (HAIS) Lab at Bern University of Applied Sciences in Bern, Switzerland.

My research lies in the general area of Human-Computer Interaction with influences from Natural Language Processing, and Machine Learning. I strive to understand how humans perceive, interact, and learn with intelligent tools. Based on these insights, I build adaptive user interfaces that go beyond static and rule-based interaction to advance the capabilities when working and learning in the digital world.

Specifically, I am driven by the vast opportunities to enhance and improve pedagogical scenarios based on recent advantages in Natural Language Processing and Machine Learning to enable humans to learn self-reliant and individually independent of an educator or their background. To do so, I use techniques from Artificial Intelligence (AI) to build AI-powered education tools. My research follows three connected main lines of work: 1) create and study pedagogical conversational agents or intelligent writing support systems to improve educational scenarios, 2) explore methods and techniques to model student performance in numerical or textual data, and 3) build computational approaches that control when, where and how to provide students intelligent feedback and self-evaluation.

As part of a research team, I have developed adaptive argumentation writing support systems which helps individuals to develop better writing and reasoning skills (Link to CHI 2020 or ACL 2022 paper). Also, I built an intelligent conversational agent that provides students with adaptive and individual argumentation tutoring while writing persuasive essays independent of an instructor, time or location (Link to CHI 2021 paper). Moreover, I designed an empathy writing support tool by modeling the cognitive and emotional empathy structures in student-written texts (Link to ACL 2021 or CHI 2022 paper).

I believe in the power of collaboration for building better AI-based systems. If you are interested in my work, please contact me via LinkedIn.

I am happy to announce that I got four full papers accepted at CHI 2024! I co-organized the Third Workshop on Intelligent and Interactive Writing Assistants at CHI 2024! More information on our website!
