I am a researcher at the Center for Cognitive and Decision Science (CDS), University of Basel, Switzerland, and an adjunct researcher at the Center for Adaptive Rationality (ARC), Max Planck Institute for Human Development, Germany.
I investigate the cognitive underpinnings of human memory and decision making using a pluralistic methodological approach involving experiments, computational modeling, big data analytics, and process tracing.
I am also the founder of The R Bootcamp, an organization of Swiss-based data scientists offering courses and consulting for academic institutions and businesses.

The Aging Lexicon Project seeks to understand adult age differences in the development of lexical and semantic knowledge.
On June 7-9, 2018, the Symposium on The Aging Lexicon gathered in Basel experts in Psychology, Linguistics, Neuroscience, and related fields to discuss open issues concerning the aging lexicon.
