My research focuses on those complex forms of cognition that are distinctly human, and indeed make us human. My experimental work in mathematical reasoning explores how people understand abstract mathematical concepts such as negative numbers, and rich mathematical notations such as place value. My experimental work in language understanding investigates how long-term memory supports sophisticated processes such as anaphor resolution and schema-based comprehension.
Behavioral experiments are not sufficient for understanding cognition, and so I also construct computational models of mathematical reasoning, language understanding, and spatial problem solving. These models account for behavioral and brain imaging data collected from normal adults and neuropsychological patients.
