Research Interests
My research explores several directions of computational cognitive neuroscience. I model animal and human behaviour in various learning, memory and decision making setups and use computational model-based analysis to find the most suitable models and investigate their neural correlates.

I'm particularly interested in how episodic memory interacts with reinforcement learning in guiding learning as well as how sensitivity to risk and discounting determine economic choices in realistic tasks and situations.

I also investigate computational roles of stress and other modulators, how they interact with individual traits to control behaviour and cognition, and how they can be used to improve cognitive performance and alleviate adverse effects of mental disorders.

Finally, I work on neuroinformatics of cognitive neuroscience and multi-voxel pattern analyses of neuroimaging data, as they are essential for obtaining a data-driven view of brain systems’ function.

Recent collaborations include Carmen Sandi (Lausanne), Dominique de Quervain (Basel) and Eleni Vasilaki (Sheffield).
