About
I am an associate professor and member of
the Programming, Logic and Intelligent
Systems research group in
the Department
of People and Technology at Roskilde
University, Denmark.
My research is in Knowledge Representation and Reasoning, a subarea
of Artificial Intelligence that studies how an agent's knowledge can
be represented symbolically and subsequently manipulated through
reasoning algorithms. Among other things, my work is concerned with
reasoning about action and change, reasoning about beliefs,
planning, agent program verification, synthesis, and machine ethics.
The ß in
my last name is a German letter that is roughly pronounced like
"ss" (as in pass), and not to be confused with a "b" or the
Greek letter beta
(β). An
alternative spelling is "Classen".

I am co-author of two papers to be presented at AAAI 2025 next week. Daxin Liu will present our paper on iteratable first-order progression, and Till Hofmann our paper on LTLf synthesis on first-order agent programs.

Next week I will be at the Nordic Workshop on Programming Theory, which I co-organized. Till Hofmann and I contributed an abstract on strategy synthesis for first-order agent programs over finite traces, which can be found here.
