RESEARCH

EPISODIC 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
