Interests

My primary research interest lies in the study of novel interactions between neurotransmitters in the basal ganglia in the context of locomotor and mood disorders. Currently I am working on whether the serotonergic system has a modulatory function on locomotor behaviours in the dopamine-deprived striatum.
