Sunita Chepuri's research interests lie in algebraic combinatorics, particularly total positivity and cluster algebras. She completed her PhD in August 2020 at the University of Minnesota under the supervision of Pavlo Pylyavskyy and is now a postdoc at the University of Michigan. During her PhD, Sunita extended the theory of plabic networks and electrical networks to surfaces beyond the disk. She also studied several aspects of k-positive matrices, objects that generalize totally positive matrices. In addition to continuing work in these areas, Sunita is currently investigating combinatorial properties of linear LP algebras. Sunita will be a Semester Postdoc at ICERM this spring as part of the "Combinatorial Algebraic Geometry" program.

Fabien Cléry received his Ph.D. in 2009 from the University of Lille 1. Since then, he has held positions at the University of Amsterdam, the University of Hannover, the University of Siegen, the Max Planck Institute for Mathematics in Bonn, and the University of Loughborough. His research interests are on two types of modular forms focusing on the theory but also on computational aspects. The two types of modular forms that he is currently studying are Siegel modular forms and Picard modular forms. Fabien is working as a Senior Research Associate David as part of the Simons Collaboration on Arithmetic Geometry, Number Theory, and Computation.

Dr. Stefan Czimek’s research interests are in the field of mathematical analysis of the Einstein equations, with a particular focus on problems at the intersection of analysis of PDE, differential geometry and theoretical physics. Among other results, he developed new methods for (1) the construction of solutions to the spacelike constraint equations, (2) the characteristic Cauchy problem in low regularity (at the level of L2-integrable curvature), and (3) the classification of conservation laws in general relativity. After earning his Bachelor’s and Master’s degree from ETH Zurich, sponsored by the university’s Excellence Scholarship, Stefan Czimek received his doctorate at the Université Pierre-et-Marie-Curie (Paris 6) in 2017. Since then he has held positions at the Field Institute for Research in the Mathematical Sciences and the University of Toronto. He will stay at the ICERM as an “Institute Postdoc” for the academic year 2020/21 in connection with the semester program “Advances in Computational Relativity”.

Sean Griffin's research interests lie in the intersection of algebraic combinatorics, representation theory, and algebraic geometry. He earned his Ph.D. in mathematics in 2020 from the University of Washington, where he was advised by Sara Billey. His recent work is on representations of the symmetric group coming from geometry and their connections to algebraic combinatorics. He has a particular interest in generalizations of the type A Springer fibers, which are a family of varieties that have the remarkable property that each of their cohomology rings has an action of the symmetric group, even though there is no such action on the variety itself. Sean was a visiting lecturer at University of California, San Diego during Fall 2020. He will be at ICERM as a Semester Postdoctoral Fellow during the Spring of 2021, taking part in the "Combinatorial Algebraic Geometry" program.

Daoji Huang received her Ph.D. in Mathematics from Cornell University in 2020 under the supervision of Allen Knutson. She is interested in studying geometry of flag varieties, Schubert calculus, and quiver varieties, especially from a combinatorial and computational perspective. Her thesis work is on Bruhat atlas theory, which seeks to understand stratified manifolds by locally modelling them with Bruhat cells in Kac-Moody flag varieties. She is also interested in developing and improving mathematical software for computations in algebraic geometry. Daoji will be at ICERM as an institute postdoc for 2020-2021 and is affiliated with the spring semester program "Combinatorial Algebraic Geometry."

David Lowry-Duda’s research interests primarily lie in analytic number theory, and in particular on automorphic forms and L-functions. During his PhD, he developed a new approach to study the size and behavior of automorphic forms. He has contributed to data creation for the LMFDB, as well as day-to-day maintenance. David completed his Ph.D. at Brown University in 2017, worked as a postdoctoral researcher at Warwick Mathematics Institute. David has returned to ICERM as a Senior Research Associate to work with Brendan Hassett as part of the Simons Collaboration on Arithmetic Geometry, Number Theory, and ComputationCollaboration on Arithmetic Geometry, Number Theory, and Computation.

Gleb Nenashev's research interests lie at the intersection of Combinatorics and Algebra. He received his Ph.D in mathematics at the Stockholm University 2018 under the supervision of Boris Shapiro. Gleb has been a visitor at MIT and MSRI in 2017 during his PhD studies. Gleb moved to Boston after his defence, where he did postdoc at MIT (2018-2020) and is currently an instructor at Brandeis University. Gleb worked with Zonotopal Algebras and on Froberg’s Conjecture, his current research mostly focuses on flag varieties and Schubert calculus. Gleb will work at ICERM this spring as a postdoc at the semester program "Combinatorial Algebraic Geometry."
