Congratulations to Professor Piotr Sankowski on receiving the Research Star Award (pol.Gwiazda Badań) - part of the "Internationalization Stars 2026" program. This distinction honors research staff at universities and institutes whose research advances the internationalization of science and higher education in Poland and worldwide.

Until 20th of February, you can apply for the position of academic teacher in our groups of teaching staff and research&teaching staff.

As part of the MIMUW colloquium, Adam Karczmarz will deliver a talk titled “Shortest paths, edge weights, and models of computation.” The talk will take place on January 22, 2026 at 2:30 PM in the Faculty Council Room (2180).

Two courses in the series of ALGOMANET will be held from June 30th to July 3rd at the Leipzig University:
• Matija Bucić (University of Vienna): Sublinear expander graphs
• Jinyoung Park (Courant Institute of Mathematical Sciences NYU): Asymptotic enumeration via graph containers and entropy.

PhD students from MIM UW (both maths and CS) are welcome to participate.
The courses can be used as an equivalent of a PhDOpen lecture.

Registration is open until the 20th of April.

To each and one of our students, emplyees, and friends - very happy Christas AD 2025 and a fruitful and satisfying New Year 2026!

We invite you to the workshop "Compositionality and Reasoning in AI and Cognitive Science," which will take place on January 8th at the Staszic Palace. Speakers include Ian Pratt-Hartmann (U Manchester), Dieuwke Hupkes (Meta AI Research), and Andrea de Varda (MIT).

It is with great pleasure and joy that we share that two of our colleagues have just received prestigious Consolidator grants from the European Research Council.

Dr. Wojciech Czerwiński will lead the POLARIS project entitled "Reachability in Infinite Systems at High Resolution".

Dr. Michał Pilipczuk will lead the WYDRA project entitled "Towards a unified structure theory for dense graphs".

Our warmest congratulation to them both!

Congratulations to the UW2 team: Jan Gwiazda, Stanisław Karpiejczyk, and Jerzy Olkowski, who won the gold medal, second place at this year's Central Europe Regional Contest! They thereby advanced to the world finals!

Huge applause to other teams from our Faculty, three of which won medals! Kudos to the supervisors and coaches!

Krzysztof Diks's wrote as always a few words, feel invited to read the details and see some photos.

Excellent results at the ISTCiM competition. Our team MIM FORCE ONE, consisting of Korneliusz Obarski (captain), Łukasz Łopacki, Adam Naskręcki, and Mikołaj Woźniak, won the gold medal, placing second in this prestigious matematical competition.

Individually, all of our representatives also won gold medals. Adam Naskręcki deserves special mention as he solved all the problems (winning the Best Individual Performance Prize).

Congratulations to the students and their advisor, Dr. Rafał Martynek!

We warmly invite you to the Trade'M competition - registration for 3-person teams is open till the 7th of December. Have some scientific fun before Christmas and show the usefulness of modern data analysis techniques in everyday life! And try to bridge the gap between two cultures: exact sciences and humanities!
