The Corelab Seminar is an informal seminar organized by the Computation and Reasoning Laboratory. Its scope encompasses all areas of Theoretical Computer Science, and it is open to undergraduate students, graduate students, and faculty members alike. Distinguished speakers are often invited to give lectures based on their recent work.

  • When: On Mondays, at 17:00 (but check also the talk schedule below).
  • Where: Room 1.1.31, School of Electrical & Computer Engineering, National Technical University of Athens.
