Investigating the cognitive neuroscience of learning, memory, and decision-making
Behavioral, computational, & neuroimaging investigations of memory and decision-making systems. Focusing on how map-like learning mechanisms could be a widespread phenomenon in the brain beyond spatial cognition.

Artificial intelligence and spatial memory
We investigate how people use past experience to make decisions, plan for the future, and imagine potential scenarios
USING COGNITIVE MAPS IN LEARNING & DECISION-MAKING
We build on the Nobel Prize winning discovery of spatially modulated neurons in the hippocampal formation to investigate how such neural computations can inform learning and decision-making in other domains
REFERENCE FRAME TRANSFORMATIONS IN SOCIAL AND SPATIAL COGNITION
We study how ‘map-like’ coding of decision variables may inform decisions by providing coordinates and boundaries that can be translated between different frames of reference
