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".

Our warmest congratulation to them both!
