Kamil Dusznko Award for outstanding achievements in
The winner of Kamil Duszenko Award in 2023 is Nick Salter.
Nick Salter received his PhD in 2017 at the University of Chicago, under the supervision of Benson Farb. He was an NSF postdoc at Harvard and Columbia, and Ritt Assistant professor at Columbia. He is currently Assistant Professor at the University of Notre Dame.
Nick is working at the interface of geometric group theory and complex algebraic geometry. Among his achievements are answering a question of Donaldson on which simple closed curves can be vanishing cycles for nodal degenerations of smooth curves in the complete linear system for an ample line bundle on a toric surface, and confirming a conjecture of GriffithsSchmid that the monodromy group of an algebraic family of complex varieties is arithmetic for AtiyahKodaira manifolds. He also solved a series of wellknown open problems on the topology of the spaces of abelian differentials and versal deformation spaces. A unifying theme in his research is that of monodromy groups.
Nick likes to cook a lot. He is especially big fan of the cookbooks of Yotam Ottolenghi and J. Kenji Lopez Alt, and once took an Indian cooking class from Ranjana Bhargava, who is Manjul’s aunt. His wife and he also brew beer.
The winner of the Kamil Duszenko Award in 2022 is Mikołaj Frączyk.
Mikołaj Frączyk received his PhD from Université Paris–Sud in 2017 under the supervision of Emmanuel Breuillard, and is currently a Dickson Instructor at the University of Chicago. Previously he held a postdoctoral position at the Renyi Institute in Budapest and a membership at the Institute for Advanced Studies in Princeton. In 2023 he will start leading a prestigious Discouri Centre in Kraków, Poland.
Mikołaj has written 17 papers to date, concerning in particular the geometry and topology of locally symmetric spaces and expander graphs, in relation to number theory and probability.
In his impressive PhD thesis on Benjamini–Schramm convergence of locally symmetric spaces, Mikołaj established a deep result regarding the geometry of such spaces using a variety of geometric and number theoretical methods. For this he received the 2018 Thesis Prize of Laboratoire de Mathématiques Blaise Pascal in France. In breakthrough work with Gelander, he proved a famous conjecture of Margulis on the nonexistence of uniformly slim subgroups of infinite covolume in higher rank symmetric spaces. In recent work with Hurtado and Raimbault, he solved an important conjecture of Gelander on the homotopy type of arithmetic locally symmetric spaces.
As a hobby he paints.
We would like to congratulate awardee on his remarkable work and wish him many successes in the years to come.
The winner of the Kamil Duszenko Award in 2021 is Jingyin Huang.
Jingyin Huang received his PhD in 2015 from the Courant Institute at New York University under the supervision of Bruce Kleiner. He has held postdoctoral positions at McGill University and at the Max Planck Institute in Bonn, and is currently an Assistant Professor at the Ohio State University.
Jingyin has made impressive contributions to quasiisometric rigidity of various kinds of groups with some form of nonpositive curvature. He has extensively studied rightangled Artin groups via CAT(0) cube complexes, largetype Artin groups via systolicity, and finite type and FCtype Artin groups via the Helly property. More recently he has been interested in measure equivalence, further expanding the scope of his research. His achievements and promise in geometric group theory were recognized with a 2022 Sloan Research Fellowship.
As a hobby he composes classical Chinese music.
We would like to congratulate awardee on his remarkable work and wish him many successes in the years to come.
The winner of the Kamil Duszenko Award in 2020 is Camille Horbez.
Camille Horbez received his PhD from Université Rennes in 2014 under the guidance of Vincent Guirardel. He is currently a member of CNRS at Orsay and he held visiting professor positions at the University of Utah, MSRI, and the Fields Institute.
Camille wrote a spectacular thesis where he introduced random walk methods to prove the Tits Alternative and the HandelMosher Alternative for outer automorphism groups Out(F_n) of free groups, and generalisations. He wrote 20 papers to date and made further significant contributions to the study of boundaries of hyperbolic spaces on which Out(F_n) acts, and its applications such as rigidity results and boundary amenability.
He is coorganising a research semester at Institut Henri Poincaré in 2022.
His main hobby is to play the baroque flute.
We would like to congratulate Camille Horbez on his remarkable work and wish him many successes in the years to come.
The winner of the Kamil Duszenko Award in 2019 is Kathryn Mann from Brown University.
Kathryn Mann received her PhD from the University of Chicago in 2014 under the supervision of Benson Farb, and is currently a Manning Assistant Professor of Mathematics at Brown University. Previously, she held a Morrey Visiting Assistant Professorship at UC Berkeley, a postdoctoral position at MSRI, and a visiting position at the Institut de mathématiques de Jussieu.
Among her accolades is an Alfred P. Sloan Foundation Fellowship (2019), an NSF Career Award (2019), and the Mary Ellen Rudin young researcher award (2017).
Mann has developed a broad research program which concentrates on homeomorphism and diffeomorphism groups of manifolds, especially in low dimensions. Among her major achievements is a characterization of geometric representations of closed surface groups into homeomorphisms of the circle. Geometric representations come from embeddings as lattices in Lie groups. Mann proved that geometric representations of closed surface groups are globally rigid, meaning that their dynamics do not change under any deformation.
In joint work with Maxime Wolff, she established the converse to this theorem, showing that rigid representations of closed surface groups are geometric.
Kathryn Mann is a renowned educator, deeply engaged in involvement of undergraduate and graduate students in topology, and she is involved in a large number of outreach activities. She has given many talks, including several directed at a general audience.
Among her hobbies she is an avid cyclist.
We would like to congratulate Kathryn on her excellent work and superb achievements ad wish her many successes in the future.

ALESSANDRO SISTO
will give a public lecture
A beautiful nonEuclidean geometry: The hyperbolic plane
Instytut Matematyczny UWr,
Wrocław, 2/4 Grunwaldzki Square
Tuesday, 4^{th} June, 9:00, auditorium HS
IM PAN, Warszawa, ul. Śnadeckich 8
Friday, 7^{th} June, 13:30, r. 321
ABSTRACT: The hyperbolic plane is in some respects similar to the familiar Euclidean plane, with the crucial difference that Euclid’s fifth postulate fails. More specifically, there are infinitely many lines parallel to a given one and passing through a given point. We will explore this beautiful geometry and its symmetries, comparing and contrasting it to the Euclidean plane (and enjoying many nice pictures).

The winner of the Kamil Duszenko Award in 2018 is Alessandro Sisto from ETH Zürich.
Alessandro is especially interested in, and contributed significantly to the study of generalisations of hyperbolic groups: relatively hyperbolic, acylindrically hyperbolic and hierarchically hyperbolic groups. For each of these classes he proved deep and interesting results, addressing wide range of questions and using wide range of techniques: random walks, bounded cohomology, embedding obstructions.
We would like to congratulate Alessandro Sisto on his outstanding work.
On the 16th September 2017 Kate Juschenko, the winner of the second edition of the Kamil Duszenko Award visited Wrocław, where she gave a public lecture "The BanachTarski Paradox". The event took place at the Institute of Mathematics, Univeristy of Wrocław.
Before the lecture the Mayor of Wrocław, Rafał Dutkiewicz, came to meet Kate and congratulate her on winning the award. He was deeply interested in the topic of her talk.

Abstract:
The BanachTarski Paradox is the famous "doubling the ball" paradox, which claims that by using the axiom of choice it is possible to take a solid ball in 3dimensional space, cut it up into finitely many pieces and, moving them using only rotation and translation, reassemble the pieces into two balls the same size as the original.
Or short: the ball is equidecomposable with two copies of itself. For the ball, five pieces are sufficient to do this; it cannot be done with fewer than five. There is an even stronger version of the
paradox: Any two bounded subsets (of 3dimensional Euclidean space R3) with nonempty interior are equidecomposable. In other words, a marble can be cut up into finitely many pieces and reassembled into a planet.
We will discuss how exactly to do this.
