Research
Decision Making, Reinforcement Learning, Cognitive Maps, Human memory, Exploration Exploitation Dillema, Metacognition
Interests
Broadly, my research concerns the mechanisms supporting decision-making, memory and learning with a focus on how flexible control mechanisms guide behaviour. I seek to identify these mechanisms using cleverly crafted experimental designs, computational modelling, pharmacological manipulations, neuroimaging, and advanced statistical analysis of empirical data. My vision is that a better understanding of these processes will allow us to develop interventions promoting their effective usage.Current interests include:
- Model Based and Model Free Reinforcement Learning
- Credit Assignment
- The Functions of Cognitive Maps
- Sequential Sampling Models of Evidence Accumulation
- Exploration-Exploitation Dilemma
- Learning biases elicited by Disinformation
