معرفی
Sean Cotner is an NSF Research Fellow and Postdoctoral Assistant Professor in the Department of Mathematics at the University of Michigan, affiliated with the College of Literature, Science, and the Arts. He earned his Ph.D. in Mathematics from Stanford University in 2023 and a B.S. from Pennsylvania State University in 2018. His research focuses on arithmetic geometry, algebraic groups, and integral questions related to the local Langlands program. Cotner has contributed to significant publications in journals such as Inventiones Mathematicae and Compositio Mathematica.
He has held positions including a graduate research role at Stanford under Brian Conrad. Cotner’s work bridges pure mathematics disciplines, emphasizing geometric and algebraic structures. His expository writings on topics like Steinberg’s theorem and reductive groups demonstrate his commitment to advancing foundational mathematical theory.
Awarded the NSF Research Fellowship, he has also engaged in collaborative projects, including work with Jeffrey D. Adler and Bogdan Zavyalov. Cotner’s academic contributions include both original research and pedagogical efforts, such as exercises for the Arizona Winter School 2025 on representation theory of p-adic groups.
