Sollecito, who graduated with a degree in computer engineering from Verona University, analyzed the traffic the case generated on social networks, La Repubblica reported.
His thesis, which assessed the flow of comments on social networks on either his guilt or innocence, was marked 88 out of 110, the newspaper said. He was quoted by the newspaper as saying the thesis was "an experiment on me".
Kercher, from south London, was found dead in the apartment she shared with Knox in Perugia, a popular student city, on November 1st 2007.
Knox and her former boyfriend Sollecito - originally sentenced to 26 and 25 years in prison for killing Kercher - were acquitted on appeal in 2011 after four years behind bars, but then found guilty again in a shock about-turn by a Florence court in January.
La Repubblica reported that Sollecito, from Puglia, celebrated his graduation with his father and girlfriend, Greta, at a restaurant in Verona. His lawyer, Luca Maori, also attended.
Sollecito again pledged his innocence during a press conference earlier this month, although he has also distanced himself as Knox’s alibi.
Both Knox and Sollecito are appealing the verdict at Italy's Supreme Court, which will hand down the final verdict in the seven-year case.
