## Current teaching

I am a supervisor for the courses Computation Theory, Discrete Mathematics, and Logic & Proof. Below you can find the hand-in exercises for these supervisions. Supervision work can be handed in in the supervision work box at the Computer Lab, or by email. It has to be submitted at the latest 24 hours before the start of the supervision, except when the supervision is on a Monday, in which case it has to be submitted 72 hours before the supervision.

My contact information can be found here.
