Martin Olsson (Collaboration Director)

Martin Olsson is a professor and department chair at UC Berkeley.  He received his PhD from UC Berkeley in 2001 after which he took postdocs at MIT, MSRI, and the Institute for Advanced Study before joining the faculty at UT Austin.  He returned to UC Berkeley in 2006.  In addition to his research and teaching, he has served as department chair twice (2016-2019 and presently) as well as associate dean (2021-22). Among other recognitions he has received a Sloan Fellowship and Simons Fellowship.

Olsson's research spans a broad set of topics in algebraic and arithmetic geometry including algebraic stacks, logarithmic geometry, moduli spaces, derived categories, and motives.

Benjamin Antieau

Benjamin Antieau received his PhD in 2010 from UIC. After postdocs at UCLA and University of Washington, he returned to UIC as a faculty member in 2014 and moved to Northwestern University in 2020. His awards include a K-theory Prize, a Simons Fellowship, and appointment as a Fellow of the AMS.
Antieau’s research focuses on Brauer groups, algebraic K-theory, and, recently, machine calculations of syntomic cohomology.

Bhargav Bhatt

Bhargav Bhatt received his PhD from Princeton in 2010. Following postdocs at the University of Michigan and the Institute for Advanced Study (IAS), Bhatt was appointed to the faculty at Michigan in 2014, where he currently serves as the Gehring Professor of Mathematics. Starting in 2022, he has taken up the Fernholz Joint Professorship between the IAS and Princeton University. Bhatt's work has been recognized with a number of awards including a Packard Fellowship, a Compositio Prize, a Simons Investigatorship, a New Horizons Prize, a Clay Research Award, and a Nemmers Prize. He has given a number of invited lectures, including a plenary talk at the ICM in 2022.
Bhatt is broadly interested in algebraic geometry, especially its connections with number theory, commutative algebra, and algebraic topology. 

Kęstutis Česnavičius

Kęstutis Česnavičius is a chargé de recherche of the CNRS working at Université Paris-Saclay. He received his PhD in mathematics from MIT in 2014 under the supervision of Bjorn Poonen and has held positions at UC Berkeley and Universität Bonn prior to joining the CNRS in 2017. He is the recipient of the prize of the Lithuanian Mathematical Society in 2018.

Česnavičius is known for introducing the perfectoid approach to the study of cohomological purity questions in arithmetic geometry, which allowed him to resolve conjectures of Auslander–Goldman, of Grothendieck and, in joint work with Scholze, also of Gabber.

Dustin Clausen

Dustin Clausen received his PhD from MIT in 2013 under the direction of Jacob Lurie, and after positions in Copenhagen and Bonn is currently a permanent professor of mathematics at the IHES.

He is known for his work on algebraic K-theory, on connections between homotopy theory and arithmetic, and more recently and jointly with Peter Scholze, on the development of condensed mathematics and the attendant approach to analytic geometry.  

Pierre Colmez

Pierre Colmez received his PhD from Grenoble and is currently Directeur de recherche at CNRS, based in Sorbonne Université (ex-Paris 6). He received the 2005 Fermat prize and was invited speaker at ICM1998 in Berlin and ECM2012 in Krakow. He also launched the 'Documents mathématiques' series of Société Mathématique de France.

Colmez works in the $p$-adic world (Hodge Theory of $p$-adic varieties, Galois représentations of $p$-adic fields and $p$-adic Langlands program), keeping an eye on applications to Number Theory.
