Stefan Gruner is an Associate Professor of Computer Science at the University of Pretoria, Republic of South Africa. Together with Tom Maibaum, he co-supervised Apurva Kumar during her Master”s project, on the results of which some parts of this book are based. He has also collaborated with Markus Roggenbach for many years, particularly on questions concerning the formal semantics of CSP. At the University of Pretoria, Stefan Gruner lectures mostly theory based courses such as compiler construction or formal methods. With his additional qualification in philosophy, he is also active in interdisciplinary fields such as philosophy of science, philosophy of technology, and philosophy of informatics (meta informatics). Apurva Kumar completed her Masters in Applied Science from Mc Master University in 2015 under the supervision of Stefan Gruner and Tom Maibaum. Many of the findings in her Master’s thesis are incorporated in this book.Apurva Kumar is currently a security researcher on the Threat Intelligence team at Lookout Inc. She spends most of her time uncovering and tracking threats as they emerge in and around the mobile space. Her main focus is on exposing and defending against nation state surveillance campaigns. Apurva”s current work incorporates threat hunting, reverse engineering and penetration testing. Tom Maibaum is an Emeritus Professor of the Foundations of Software Engineering in the Department of Computing and Software, Mc Master University, Canada. He now lives in The United Kingdom. Previously, he held similarly named Chairs at King’s College London and Imperial College London. Throughout his career, his research has focused on the logical and categorical bases of software engineering and on the applications of these topics to software engineering methods. He has studied the philosophical and epistemological bases of engineering and, in particular, software engineering. Over the past 15 years he has worked with Mark Lawford and Alan Wassyng at Mc Master University in the context of the Mc Master Centre for Software Certification, developing new logical and epistemological foundations of safety reasoning. Markus Roggenbach is a Professor of Computer Science at Swansea University, The United Kingdom. His research foci are formal methods for safety and for cyber security, their semantics, how to utilise them throughout the software life cycle, how to support them with tools, and their application in industrial contexts. For more than a decade, he has been collaborating with Siemens Rail Automation (formerly Invensys Rail) to answer questions concerning safety with regard to railway signalling systems. He leads the Swansea Railway Verification Group, the European Technical Working Group on Formal Methods in Railway Control, and chairs the International Federation for Information Processing (IFIP) Working Group 1.3 “Foundations of System Specification”.
