Curriculum Vitae

Thom Frühwirth is the developer of the programming language and formalism Constraint Handling Rules (CHR) and author of the eponymous book. He has (co-)authored five books on constraint programming and reasoning, including a leading textbook. He is also known for his work in type theory and spatio-temporal reasoning. He is among the top researchers in Computational Logic. He is the editor of 11 books in this area. He has published more than 200 research papers with close to 5000 citations. He has served on more than 100 program committees. He has given more than 100 invited talks. He has been involved in 15 publicly funded research projects.

Thom Frühwirth teaches and publishes since 1984. He obtained his Ph.D. in Computer Science at the Technical University of Vienna in 1990, after visiting the State University of New York at Stony Brook with a one-year Fulbright grant and invitations to the Weizmann Institute of Science in Rehovot. From 1991 he was researcher at the European Computer Industry Research Centre in Munich. In 1996 he joined the Ludwig Maximilians University in Munich. There he became assistant professor in 1998 after his habilitation and held visiting positions at the universities of Pisa, Monash Melbourne, PUC Rio de Janeiro, and the CWI research center in Amsterdam. In 2002 he was appointed professor at Ulm University, Germany, and entered into collaboration with the German University in Cairo. He served on the examination board for Computer Science for 17 years, the PhD committee for 15 years, on the examination board for Cognitive Systems, and on the habilitation committee. [Full CV up to 2005].

Finally...

"The perfect crime is that of an unconditional realization of the world by the actu­alization of all data, the transformation of all our acts and all events into pure information: in short, the final solution, the resolution of the world ahead of time by the cloning of reality and the extermination of the real by its double."
The Perfect Crime, Jean Baudrillard, 1996
