I am interested in the relation between sleep, homeostasis and decision making. Particularly, I am investigating the following questions: Does sleep deprivation increase the value of rewards? What are the underlying neural correlates? Is there a hormonal modulation of sleep state-dependent changes in decision-making and rewarding values?

In current studies I use economic tasks, hormonal assessment, psychophysiology, functional magnetic resonanceimaging (fMRI), and electroencephalography (EEG).
