Prof. Dr. Jürgen Dix

I am (emeritus) Professor at the Computer Science Department of Clausthal University of Technology. I held my chair from 2004-2024 and retired in October 2024.

Since the late eighties, I have been working in symbolic/logic-based Artificial Intelligence.

I served as lead liason professor of the German National Merit Foundation (federführender Vertrauensdozent der Studienstiftung des deutschen Volkes) from 2007-2024.

I am full member (ordentliches Mitglied in der Klasse für Mathematik und Naturwissenschaften) of the Braunschweigische Wissenschaftliche Gesellschaft since 2017.

I am Editor-in-Chief of The Annals of Mathematics and Artificial Intelligence since January 2025.

While I am still active in research (an ongoing project since more than 20 years is the Multi-Agent Programming Contest), I am not taking on any BSc/MSc or PhD students anymore: please refrain from contacting me in this matter.

Previously (1999-2003) I was Reader at the Computer Science Department of Victoria University in Manchester (UK), visiting Assistant Professor at the Computer Science Department of the University of Maryland (in 1999) and wissenschaftlicher Assistent (C1) at the Computer Science Department at the University of Koblenz-Landau (1993-2000). 

I served as Head of Department of the Department of Computer Science (2005-2008), as Dean of the faculty of Mathematics, Computer Science and Engineering (2008-2011 and 2014-2017) and as Vice-Dean (2001-2014 and 2017-2021).

I have co-authored four monographs, more than 10 chapters in books, more than 50 articles in international journals, and more than 70 conference/workshop papers.

I (co-) edited more than 20 books (LNCS/LNAI) and more than 15 special issues of international journals.

Please find more detailed information about my publications below.
 

All publications (PDF)  - Publications of my group (including BSc and MSc theses) until 2024 can be found here.
