Thiago was studying Business Administration at UERJ when he received an invitation to test for the part of a professor of swimming in Malhação.

Two years later, the actor appeared as protagonist of the novela Terra Nostra, in which he played Matteo, an Italian immigrant who came to Brazil seeking a better life.

After his success as Matheo, he participated in the miniseries Aquarela do Brasil and the novelas As Filhas da Mãe and O Beijo do Vampiro.

The actor considered the role a real gift, because, since the time of Terra Nostra, he had studied and admired the life of the Italian revolutionary.

Hounded by paparazzi and gossip media, he sued the journalist and presenter Leão Lobo and Gugu Liberato, who wore swimwear in a program called Domingo Legal claiming to be the actor - and won both cases.
