Johannes Marti
I am a postdoc at the ILLC in Amsterdam working with
Yde Venema on
cyclic proof systems for modal fixpoint logics.
Before, I did postdocs with Carsten Lutz in
the Theory of
Artificial Intelligence group at the University of Bremen and with
Clemens
Kupke in the MSP
group at the University of
Strathclyde in Glasgow.
I completed my dissertation under the supervision Martin Stokhof and Frank Veltman
also at the ILLC. My
PhD thesis is on representation theorems for possible world
models of belief and meaning with respect to linguistic
behavior.
