Martijn Willemsen is an Associate Professor on human decision making in interactive systems at JADS and TU/e (HTI group). He researches the cognitive aspects of Human-Technology Interaction, with a strong focus on judgment and decision making in online environments. From a theoretical perspective, he has a special interest in process tracing technologies to capture and analyze information processing of decision makers. His applied research focuses on how (online) decisions can be supported by recommender systems, and includes domains such as movies, music, health-related decisions (food, lifestyle, exercise) and energy-saving measures. His recent focus is on interactive recommender systems that help users to move forward, developing new preferences and/or healthier behavior, rather than reinforcing their current behaviors. Such systems can provide personalized behavioral change. Martijn also focusses on explainable AI and trust in AI, with recent work studying health and sport coaches interacting with prediction models. Since early 2024, Martijn serves as the Program Director for the master’s program “Data Science in Business and Entrepreneurship.”
