I am interested in understanding information processing in the prefrontal cortex, the premotor cortex, and the striatum in the context of choosing actions to obtain reward and how the midbrain dopaminergic system influences signal integration in the striatum.

My projects include three lines of investigation:

1. Action selection and motor control
2. Reward-guided choice behaviour in an ambiguous environment (social or economic)
3. Learning processes associated with changes in action-outcome contingencies

I am using either simultaneous dual-neuron recordings, fMRI tools, or Reinforcement Learning models in behaving macaque monkeys according to project requirement.

I aim to investigate learning-related changes in neuronal activities, with an emphasis on the following aspects:

1. Functional organization of the striatum and its connectivity, related to information processing
2. Signal processing in Basal Ganglia neuronal microcircuit
3. Social and economic values processing in fronto-striatal functional connectivity
   
4. Cortico-striatal functional connectivity during complex decisions
