(co-)organized by Jan Krajicek

During 1999 - 2011 I organized annually Fall schools of Logic and Complexity. These were aimed and graduate students and postdocs.

I was also a (co-)organizer of, or responsible for the scientific program at, a number of workshops and conferences. Here are selected few (in the anti-chronological order) from the last not so many years:

- Tribute to Kurt Godel 2020, Brno, January 13-15, 2020 (PC member),

- Logic in Computer Science, New York City, USA, July 5-8, 2016 (PC member)

- Dagstuhl seminar Optimal algorithms and proofs, Schloss Dagstuhl, Germany, October 12.-17., 2014 (a co-organizer)

- Logic and Interactions, CIRM in Luminy, France, April 29 - May 3 2013 (PC member)

- Logic and Computational Complexity (within FLoC), Edinburgh, July 2010 (PC member).

- Theory and Applications of Models of Computing, Prague, June 2010, (Proof Complexity special session org.)

- Logic Colloquium, Bern, July 2008 (pc member, spec.sect. org.).

- New directions in proof complexity, a workshop at

the Isaac Newton Institute in Cambridge in April'06 (principal organizer).
