Elena Di Lavore
Research associate at the University of Oxford

I am a research associate at the University of Oxford, working with Sam Staton as a creator for the ARIA Safeguarded AI program. Previously, I was a postdoctoral researcher at the University of Pisa, working with Filippo Bonchi. Until November 2023, I was a PhD student in the Compositional Systems and Methods group at Tallinn University of Technology under the supervision of Paweł Sobociński.
