Hello, I'm
Scientist · Innovator · Engineer
Great Minds Fellow at the University of St. Gallen, working at the intersection of Artificial Intelligence, Software Security, and Technology Innovation.
A computer scientist with a passion for building technology that matters — bridging cutting-edge research with real-world impact.
Luca Di Grazia holds a Great Minds Fellowship at the University of St. Gallen in Switzerland, focusing on the security of AI-generated code, hosted by Prof. Dr. Guido Salvaneschi. Previously, he was a Postdoctoral Researcher at USI Lugano, working on GenAI for software testing and verification under Prof. Dr. Mauro Pezzè.
He earned his Ph.D. in Computer Science (summa cum laude) from the University of Stuttgart, supervised by Prof. Dr. Michael Pradel. His dissertation explored innovative approaches to software maintenance through search and predictions.
During a Research Internship at Uber in Amsterdam, he developed a GenAI-based bug-fixing approach that won an internal competition against 103 teams, with results presented directly to the Uber CEO.
