Alexander Sistko

Assistant Professor, Mathematics

Alexander Sistko received his Ph.D. in Mathematics from the University of Iowa in 2019. His current research interests lie in noncommutative algebra, representation theory, combinatorics and the field with one element. His Ph.D. dissertation studied subalgebra varieties of finite-dimensional associative algebras.
