Catalin is a Researcher at Inria Paris where he develops rigorous formal techniques for solving security problems. He is particularly interested in: formal methods for computer and network security (isolation, access control, information-flow control, integrity, security protocols), programming languages (rigorous semantics, type systems, verification, property-based testing, formal metatheory, formally certified tools), and the design and verification of security-critical systems (reference monitors, secure hardware, security-preserving compilers, etc). He received a PhD in Computer Science from Saarland University and afterwards worked for a while as a Research Associate at the University of Pennsylvania.
