In this week's podcast, Dr. Darbari talks to Professor Alastair Donaldson. He talks about a range of topics in software verification and describes how he went from being a keen musician to being a professor in computer science at Imperial College, London, and a software engineer at Google. We talk about formal verification, metamorphic testing, concurrency, compilers, OpenCL, OpenGL, compiler bugs, the semantics of programming languages, SMT solvers, Z3, and as Alastair points out everything that is focussed on software correctness, performance, and portability. We also discuss computer science education at Imperial College.
