Timo Koch is a postdoctoral researcher at the Institute of Behavioral Science and Technology at the University of St. Gallen. He is passionate about leveraging technology (e.g., artificial intelligence, natural language processing, mobile sensing) to enhance peoples’ and society’s health and well-being. His research interests lie in the analysis of behavioral and language data, (interpretable) machine learning, and Human-AI interaction.
Timo works in the SNSF-funded ACTWELL (”Activities, Contexts, and Traits in Well-Being in Everyday Life Longitudinally”) project that investigates digital traces of well-being in smartphone data.
He received his bachelor’s degree in Psychology with a minor in Business Administration at University of Mannheim. He obtained his master’s degree in Work, Organizational and Social Psychology at LMU Munich, where he also completed his Ph.D. in Psychological Methods.
