Annabelle McIver is a professor of Computer Science at Macquarie University in Sydney. Annabelle trained as a mathematician at Cambridge and Oxford Universities. Her research uses mathematics to prove quantitative properties of programs, and more recently to provide foundations for quantitative information flow for analysing security properties. She is co-author of the book “Abstraction, Refinement and Proof for Probabilistic Systems”, and of the forthcoming title "The Science of Quantitative Information Flow”.
