I am a postdoc with Dan Olteanu in the Data Systems and Theory group at the University of Zurich.

Before, I did postdocs with Michael Benedikt at the Department of Computer Science in Oxford, with Yde Venema at the ILLC in Amsterdam, 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 at the ILLC. My PhD thesis is on representation theorems for possible world models of belief and meaning with respect to linguistic behavior.
