Research Interests

Our knowledge of the world shapes our path through it: the decisions we make, the things we attend to and ignore, and what we think we know about an unfamiliar environment when we enter it for the first time. How this knowledge is acquired, and a brain-based account of what that knowledge is and how it is physically represented in the brain, are critical questions for cognitive psychology and cognitive neuroscience. My research applies a combination of behavioral research, computational modelling, machine learning, and neuroimaging to investigate the representational format of semantic knowledge.

Some active lines of research include:

• Applying experimental machine learning tools to discover complex brain networks in neuroimaging data that are associated with semantic knowledge.
• Exploring the context-sensitivity of semantic knowledge, both to experimental manipulation and with respect to individual differences
• Building computational models of reading that study in the interplay of written and spoken language with semantic knowledge.
• Studying computational models as simulated students that can be taught by “machine teachers” that explore the training space to build effective (and possibly counterintuitive) curricula.
