In his dissertation, finished in 1981 and advised by Miquel Taradell, Dupré studied the architectural terracottas of Juno’s sanctuary in Gabii (Lazio, Italy).

Once there, he instigated various research and restoration projects at the circus and provincial forum of Tarraco, the ancient Roman capital of the Tarraconensis province.

TED’A was part of the trade schools and workshops programme run by the Spanish Ministry of Labour and the European Social Fund.

The first was to train different specialists in Tarragona’s archaeological heritage, preparing them to find employment by furnishing them with the necessary theoretical knowledge and practical experience.

He kept studying the Roman heritage of Tarragona through the organisation of the XIV International Congress of Classical Archaeology,[6] held at Tarragona in 1993 by the International Association of Classical Archaeologists and his doctoral thesis on the Berà Roman arch, finished in 1992 and awarded by the XII Premi Josep Puig i Cadafalch prize by the Institut d’Estudis Catalans.

The Tusculum project, which was coordinated by EEHAR and led by Dupré involved several universities and archaeological institutions from Italy and Spain and became a nexus of scientific exchange between the countries.

The International Association of Classical Archaeology also held a one-day conference in his honour at the Università degli Studi di Roma La Sapienza.

[10] To mark the occasion, local association XI Comunità Montana del Lazio Castelli Romani e Prenestini erected a monument at the start of the path to the site commemorating his work.
