Medico farmacologo e tossicologo, mi occupo di salute mentale e dipendenze patologiche.

Ma anche (e soprattutto) regista amatoriale, radiofonico, educatore cristiano «fin troppo ribelle», amichevole informatico di quartiere, creativo in costante crisi.

Antifascista e petulante socialista.

Se sono in un punto panoramico e non vedo il mare mi sale l’angoscia.
