- Working Memory
- At the shortest timescales, we rely on stimuli in our environment to support action. At long timescales, we develop routines, skills and explicit memories stored in persistent neural changes. Working memory lies in the crucial intermediate timescale where the maintenance and manipulation of online information is used to guide flexible and dynamic action.
- Executive Control
- Much of the brain is dedicated to the stimulus-response arc — perception of stimuli, response selection, and action generation. But a critical component of the human information processing system, executive control, is the modulation of these pathways based on changing goals and context.
- Decision Making
- Our environment provides input which is often understood as novel combinations of previously learned concepts. We store this recent information in working memory and through executive control processes use it to modulate ongoing behavior and generate novel sequences of skilled actions. Decision making is the selection of responses based on current goals, past experience, and expectations about future outcomes.
- Consider a basketball player in a game. She has a repertoire of skills at her disposal — passing, dribbling, shooting — built up through dedicated practice. This depends on long-term memory. And she reacts instantaneously to her immediate surroundings — catching the ball when she sees it flying towards her, and dodging a screen when she hears her teammate's warning. This depends on rapid perception and action. But in addition, she runs a particular play her coach recently called during a timeout, she employs a different strategy near the end of the game than she used just minutes earlier, and she improvises when she recognises the defense has switched from man to zone defense. All of this depends on maintaining and updating recently acquired information in working memory, using executive control processes to maintain focus on the task at hand, and selecting and performing novel combinations of skills.
- Computational Modeling
- Building symbolic, neural network, and Bayesian models of mental and neural processes.
- + Cognitive Psychology
- Developing behavioral experiments to decompose mental processes into their constituent parts.
- + Cognitive Neuroscience
- Applying functional brain imaging to analyze neural processes during task performance.
- = Computational Cognitive Neuroscience
- A synergistic combination of methods used to build computational theories explaining mental and neural processes, the goal of which is to explain how “the mind is what the brain does”.

- Combined Major in Psychology and Computer Science
- I'm excited to supervise students for their CSC 497 Interdisciplinary Project!
- Undergraduate Honours
- I'm open to supervising Honours students, particularly if you are interested in a project with a computational modeling component.
- As I am now primarily focused on teaching, I am not available as a primary supervisor for graduate students. However, I am still open to co-supervision or participating on supervisory committees.
