Software correctness is becoming an increasingly important concern as our society grows more and more reliant on computer systems. Even the simplest of software errors can have devastating financial or security implications. How can we find errors in real-world applications? How can we guarantee that such errors don't exist? To even begin to answer these questions we need a specification: a description of what it means for a piece of code to be correct, stated either explicitly (e.g. my private data are never leaked to third parties) or implicitly (e.g. this code will not terminate with an uncaught exception). In this talk, I will discuss efficient ways to debug and reason about software and specifications, focusing on two techniques and their interplay: property-based testing and mechanized formal verification. Testing can quickly uncover errors in complex software, but it cannot guarantee their absence. Formal verification provides strong correctness guarantees, but is still very expensive in time and effort. Together, they are a match made in heaven.
Dr. Leonidas Lampropoulos is currently pursuing a joint PostDoc between the University of Maryland, College Park, under the advice of Mike Hicks, and the University of Pennsylvania, under Benjamin Pierce. He is a Victor Basilic Postdoctoral fellow. Dr. Lampropoulos’ research interests span programming languages, random testing and verification.Posted 1 month ago
