Ethan Monaghan Ackelsberg

Ethan Monaghan Ackelsberg is a postdoctoral researcher at the Institute of Mathematics, École Polytechnique Fédérale de Lausanne (EPFL), affiliated with the School of Basic Sciences (SB) and the Ergodic Theory group (ERG). He also holds a lecturing position in the SMA-ENS program within the SB-SMA department at EPFL, focusing on teaching mathematics. His research bridges ergodic theory, Ramsey theory, and combinatorial number theory, with a focus on recurrence properties and polynomial configurations.

• Education: PhD in Mathematics from Ohio State University (2022), MS in Mathematics (2019), BA in Mathematics and Physics from Bard College at Simon's Rock (2016).

Ethan's research explores measure-preserving actions of abelian groups, polynomial patterns in large subsets, and connections to number theory. His recent work includes advancements in equidistribution in nilpotent groups and counterexamples to Erdős-type problems.

He has received academic honors including summa cum laude at Bard College and highest honors from Budapest Semesters in Mathematics. Ethan actively contributes to teaching, including courses on measure theory.
