In 2022, the International Congress of Mathematicians — the most important meeting of the world's mathematical community — will take place in St. Petersburg. The main part of the scientific program of the congress is plenary talks. These are hour-long lectures given by world-famous mathematicians. The program committee (whose composition is kept a secret until the opening ceremony) has selected the plenary speakers, who all have accepted invitations to speak at the ICM 2022. Their names are published on the Congress website. The plenary speakers comprise 21 of the world's leading mathematicians, representing 10 countries and all areas of mathematics.

**Michel Van** **den Bergh **is a Belgian mathematician and professor at the Free University of Brussels and Hasselt University. He studies the relationship between geometry and algebra. From the beginning of his career, Van den Bergh has been working on non-commutative geometry, a geometric approach to non-commutative algebras.

**Mladen Bestvina** is an American mathematician with Croatian roots, professor at the University of Utah. Bestvina is working in geometric group theory. His outstanding mathematical career began at school — he won the International Mathematical Olympiad three times. In 2002, he gave a talk at the International Congress of Mathematicians in Beijing.

**Bhargav Bhatt** is an Indian-American mathematician and professor at the University of Michigan. Bhatt is specializing in arithmetic algebraic geometry, number theory, commutative algebra, and homotopy theory. In 2021, he won the prestigious New Horizons in Mathematics Prize “For outstanding work in commutative algebra and arithmetic algebraic geometry, particularly on the development of p-adic cohomology theories.”

**Svetlana Jitomirskaya** is an American mathematician, who was born in Kharkiv. She defended her Ph.D. thesis in her alma mater — Lomonosov Moscow State University — under the supervision of Yakov Sinai, who became the winner of the Abel Prize in 2014. Now Svetlana Jitomirskaya is a professor at the University of California, Irvine. She is studying the spectrum of quasiperiodic Schrödinger equations. She spoke at the International Congress of Mathematicians in 2002 and at the International Congress on Mathematical Physics twice.

**David Kazhdan** is an Israeli mathematician born in Moscow, professor at the Hebrew University of Jerusalem and Harvard University. He published his first scientific article while at school, defended his Ph.D. thesis at the Lomonosov Moscow State University before the appointed time. Kazhdan is rightfully considered one of the best scientists of Gelfand's mathematical school. he is 2012 Israel Prize in Mathematics and 2020 Shaw Prize winner.

**Igor Krichever **is a Russian and American mathematician, professor of Skolkovo Institute of Science and Technology, a leading researcher at the L.D. Landau Institute for Theoretical Physics of Russian Academy of Sciences, professor of the Higher School of Economics and Columbia University. Krichever is studying algebraic geometry and mathematical physics.

**Alexander Kuznetsov **is a Russian mathematician, a leading researcher at the Steklov Mathematical Institute of the Russian Academy of Sciences. He works in algebraic geometry and derived categories of coherent sheaves. In 2008, Kuznetsov became a laureate of the European Mathematical Society Prize. He made a speech at the International Congress of Mathematicians in Seoul in 2014.

**Camillo De Lellis **is an Italian mathematician specializing in the calculus of variations, geometric measure theory and hydrodynamics. De Lellis won the 2013 Fermat Prize. In 2010, he gave a talk in one of the sections of the International Mathematical Congress.

**Frans Pretorius** is a South African physicist specializing in general relativity. Pretorius numerically investigated the collision of black holes. In 2017 he was awarded the New Horizons in Physics Prize for the first computer code that can simulate spiral movement and fusion of two black holes.

**Laure Saint-Raymond** is a French mathematician who studies nonlinear differential equations. Saint-Raymond is known for her research of relationships between systems of interacting particles, the Boltzmann equation and fluid mechanics. In 2008, she received the prize from the European Mathematical Society, in 2015 — the Fermat Prize, in 2020 — the Bocher Prize.
