With extensive academic and fieldwork experience, he has published findings about sites in Afghanistan, Nepal, India, and China in particular.
Verardi has joined or directed several long archaeological missions to central Asia, and held positions on numerous Italian scientific boards.
In the 1980s Verardi participated in the activities of the German-Italian Mission to Mohenjo-daro in Pakistan, where he could ascertain that the so-called stūpa-cum monastery rising upon the ruins of the Indus town is nothing but the articulated late phase of the Indus religious/ritual building, erroneously interpreted as a Buddhist structure by John Marshall.
Between 1998 and 2003, Verardi was co-director of the Italian-Chinese team engaged in the excavation of the Fengxiansi monastery at Longmen near Luoyang, connected with the Empress Wu Zetian (AD 690‒705) and rebuilt during the Song dynasty.
