Jan Bergstra


Jan Bergstra

Jan A Bergstra is a Dutch computer scientist. His work has focussed on logic and the theoretical foundations of software engineering, especially on formal methods for system design. He is best known as an expert on algebraic methods for the specification of data and computational processes in general.

Biography

Jan Bergstra was born in 1951 in Rotterdam, the son of Tjeerd Bergstra and Johanna Bisschop. He was educated at the Montessori Lyceum Rotterdam (gymnasium beta) and then studied mathematics at Utrecht University, starting in 1969. After an MSc he wrote a PhD thesis, defended in 1976, on recursion theory in higher types, under the supervision of Dirk van Dalen.

Bergstra held posts at the Institute of Applied Mathematics and Computer Science of the University of Leiden (1976-82), and the Centre for Mathematics and Computer Science (CWI) in Amsterdam. In 1985 he was appointed Professor of Programming and Software Engineering at the University of Amsterdam and, at the same time, Professor of Applied Logic at Utrecht University; such split positions are not uncommon in the Netherlands. These two chairs he continues to hold.

He has been an Advisor of the CWI (1985-2004). In 1989 he worked for a year at Philips Research in Eindhoven as a project leader and, subsequently, continued as a consultant there until 2002. While at Philips he was involved in industrial projects on consumer electronics and medical equipment.

He founded CONCUR, the international conference series in Concurrency Theory, by organising the first two conferences in Amsterdam in 1990 and 1991. He is a member of several editorial boards, and is the managing editor of Science of Computer Programming and the Journal of Logic and Algebraic Programming.

He is honorary Professor of Computer Science at Swansea University and a member of Academia Europaea.

Work on Formal Methods

Jan Bergstra's research on computation has focussed on fundamental concepts, mathematical theories and practical tools.

His main theoretical research programmes are:
* a systematic study of specification methods for abstract data types (starting in 1979, with John V. Tucker);
* the invention, development and application of process algebras, especially ACP (starting in 1984, with Jan Willem Klop, Jos Baeten and others);
* Module Algebra (starting in 1986, together with Paul Klint and Jan Heering);
* Program Algebra (starting in 1998, with Marijke Loots).

Based in this theoretical research, he has designed various formal methods and tools. In cooperation with Paul Klint and Jan Heering he designed the specification language ASF (in 1984) and the related ToolBus coordination language and system (in 1995). Some of his work has been undertaken in the setting of the ESPRIT programme. For example, the software projects FAST and METEOR funded the beginnings of the development of the process algebra ACP, and the telecommunications project SPECS led to the development of the specification language muCRL. All systems are still in daily use for research purposes, while ASF has been extensively used in the Dutch banking industry.

Work in Academia

Through his research and organisational activities, Bergstra has had considerable influence on computer science in the Netherlands. For example, he has supervised the work of over 40 PhD students, many of whom have become academic computer scientists, 12 at professorial level. He set up the new computer science curriculum at Leiden (in 1976), and for cognitive artificial intelligence at Utrecht University (in 1989). In 2000 he became the Director of the Teaching Institute of Information Sciences at the University of Amsterdam. In this role he has been responsible for the redesign of all courses when the bachelor-master system of degrees was introduced into the Netherlands.
