I am a cognitive scientist interested in computational models for human cognition. As a postdoctoral researcher in the Digital Linguistics Lab, I investigate memory and language processing in children, younger, and older adults by combining experimental data, cognitive modeling, and machine-learning techniques.

Before joining the Digital Linguistics Lab, I have been a postdoctoral researcher at the Cognitive Psychology Unit at UZH and Center for Economic Psychology, University of Basel, where I built computational models for human memory and decision making, including effects of aging and cognitive training. I conducted my PhD research at the Center for Adaptive Behavior and Cognition at the Max Planck Institute for Human Development, Berlin, Germany, and Carnegie Mellon University, Pittsburgh, PA, USA. In this research, I explored the cognitive foundations of decision making by combining human behavioral and neuroimaging data with cognitive architectures.
