EATCS Statement
I am honored to have been nominated for the EATCS Council elections. If elected, I would be delighted to contribute to EATCS and work towards enhancing the already high-quality scientific environment of theoretical computer science in Europe. If given the opportunity, my focus would be on the following:
- working for fair and inclusive reviewing systems for publications (i.e., conferences and journals), grants, prizes, and workshops/seminars
- pushing for the move from publishers with bad pricing models to non-profit publishers
- while recognizing the benefits of physical meetings and in-person conferences, supporting measures for a more sustainable behaviour in our area (my group and I are committed to the TCS4future manifesto)
- representing the algorithm engineering side of theoretical computer science
Not reviewing for Elsevier journals; see here why.
Link to a notable article on CS conferences and climate emergency. And to a follow-up article.
