- The seminar will resume in September.
Study and Work Opportunities
Job calls
The ICS and the Czech Academy of Sciences regularly open calls for postdoctoral researchers, and tenure-track positions are opened on a yearly basis at the ICS. Let us know if you are interested in applying.
Current calls:
- CAS–ICS Postdoctoral Position, deadline 10 September.
- Tenure track position -- Artificial Intelligence, deadline 20 November
- Tenure track position -- General focus, deadline 20 November
The ICS welcomes applications within international schemes such as the MSCA Postdoctoral Fellowships. Applications are particularly encouraged since the government of the Czech Republic supports no-money MSCA-PF projects. Let us know if you're interested in applying.
Teaching and thesis supervision
Members of the group offer supervision of Master and PhD theses focusing on their research topics. We can serve as supervisors and co-supervisors for students based at universities in and outside the Czech Republic. Get in touch if you're interested in writing your thesis with us.
Current PhD students:
- Filip Jankovec (supervised by Petr Cintula)
- Chun-Yu Lin (supervised by Marta Bílková)
- Pietro Vigiani (co-supervised by Igor Sedlár at the Scuola Normale Superiore di Pisa)
Past PhD students:
- Adam Přenosil (supervised by Marta Bílková at the Charles University in Prague, thesis Reasoning With Inconsistent Information defended in 2018)
- Karel Chvalovský (supervised by Marta Bílková at the Charles University in Prague, thesis Undecidability of Some Substructural Logics defended 2015)
