Reseach Theme

Synapses, Circuits and Behaviour    


The main goal of my research is trying to understand computational mechanisms of learning, memory and decision making as well as how various modulatory factors such as stress, sleep, uncertainty and future discounting affect them.

In particular, we employ reinforcement learning and related models and focus on the role of schemas in these processes, which we address using human studies and animal experiments. We have developed ecologically valid human tasks that integrate schema-based learning and decision making. We also continue the development of online platforms that can be used for digital phenotyping and testing our laboratory-based findings in much larger samples and more interactive settings.

Finally, we also work on large-scale analysis of fMRI data and individual prediction of various emotional and memory phenotypes using multi-voxel pattern analysis.
