Congratulations to:
Monika Kudlinska, for her transformative ideas showing how free-by-cyclic groups are much more badly behaved than fundamental groups of 3–manifolds, while also providing a collection of tools for their study which will have a lasting impact on the field.
Philipp Jettkant, for his versatility, great intuition and technical skill, including the use of sophisticated numerical algorithms, to address novel mean field problems with theoretical developments which will be of much wider interest.
