Dr. Markus L. Schmid

I am currently working as a researcher in the Theoretical Computer Science research group, Trier University, led by Henning Fernau.

My general research interest lies in automata theory, formal language theory, and (parameterised) complexity theory.

On this page, you can find information about my research and my academic activities. For contact details, please visit my university page.

The best way to reach me is by email. My email address is "x@x.de" with x = mlschmid.
