Research Activity

The major aim of my research is devoted to the study of the serotonin and melatonin systems that share the same precursor, the amino acid tryptophan, to determine the extent to which these metabolically connected systems are involved in the etiology and treatment of mood disorders, Moreover, during the past 5 years, I am starting to expand my interests to other possible psychopharmacological targets (e.g. the endocannabinoid system) and therapies (the transcranial direct current stimulation (tDCS) and low-dose psychedelics) for mood disorders. The ultimate goal is to increase our understanding of the neurobiological/pathophysiological mechanisms of mood disorders, and with this novel knowledge to develop new pharmacologically psychoactive compounds. Moreover, in the view of a personalized medicine approach of psychiatric disorders, I also aim to implement a series of biomarkers of disease and of treatment response.
