Dominik Gruntz has a PhD from ETH Zürich and has been a Professor of Computer Science at the University of Applied Sciences FHNW since 2000. Besides his research projects, he teaches a course on concurrent programming. Some years ago, the goal of this course was to convince the students that writing correct concurrent programs is too complicated for mere mortals (an educational objective that was regularly achieved).

With the availability of high-level concurrency frameworks in Java and Scala, this has changed, and this book, Learning Concurrent Programming in Scala, is a great resource for all programmers who want to learn how to write correct, readable, and efficient concurrent programs. This book is the ideal textbook for a course on concurrent programming.

Zhen Li acquired an enthusiasm of computing early in elementary school when she first learned Logo. After earning a Software Engineering degree at Fudan University in Shanghai, China and a Computer Science degree from University College Dublin, Ireland, she moved to the University of Georgia in the United States for her doctoral study and research. She focused on psychological aspects of programmers' learning behaviors, especially the way programmers understand concurrent programs. Based on the research, she aimed to develop effective software engineering methods and teaching paradigms to help programmers embrace concurrent programs.

Zhen Li had practical teaching experience with undergraduate students on a variety of computer science topics, including system and network programming, modeling and simulation, as well as human-computer interaction. Her major contributions in teaching computer programming were to author syllabi and offer courses with various programming languages and multiple modalities of concurrency that encouraged students to actively acquire software design philosophy and comprehensively learn programming concurrency.

Zhen Li also had a lot of working experience in industrial innovations. She worked in various IT companies, including Oracle, Microsoft, and Google, over the past 10 years, where she participated in the development of cutting-edge products, platforms and infrastructures for core enterprise, and Cloud business technologies.

Zhen Li is passionate about programming and teaching. You are welcome to contact her at <[email protected]>.

Lukas Rytz is a compiler engineer working in the Scala team at Typesafe. He received his PhD from EPFL in 2014, and has been advised by Martin Odersky, the inventor of the Scala programming language.

Michel Schinz is a lecturer at EPFL.

Samira Tasharofi received her PhD in the field of Software Engineering from the University of Illinois at Urbana-Champaign. She has conducted research on various areas, such as testing concurrent programs and in particular actor programs, patterns in parallel programming, and verification of component-based systems.

Samira has accompanied her research with valuable practical experiences by working at several IT companies, such as Microsoft and LinkedIn during the past few years. Samira has reviewed several books, such as Actors in Scala, Parallel Programming with Microsoft ^® .NET: Design Patterns for Decomposition and Coordination on Multicore Architectures (Patterns and Practices), and Parallel Programming with Microsoft Visual C++: Design Patterns for Decomposition and Coordination on Multicore Architectures (Patterns & Practices). She was also among the reviewers of the technical research papers for software engineering conferences and workshops, including ASE, AGERE, SPLASH, FSE, and FSEN. She has served as a PC member of the 4th International Workshop on Programming based on Actors, Agents, and Decentralized Control (AGERE 2014) and 6th IPM International Conference on Fundamentals of Software Engineering (FSEN 2015).
