Kaitlin Ragosta

Kaitlin Ragosta is a visiting researcher in the Department of Mathematics at Brandeis University, having completed her PhD at the same institution in August 2025 under the supervision of Professor Carolyn Abbott. Her doctoral research constructed an analogue of the marking graph for finite-type Artin groups and provided foundational insights into combinatorial hierarchical hyperbolicity.

Her educational background includes:

• PhD in Mathematics, Brandeis University, 2025

Dr. Ragosta specializes in geometric group theory with emphasis on hyperbolicity generalizations—including acylindrical and hierarchical hyperbolicity—and structural properties of groups such as finite quotients and decidability. Her work is particularly distinguished by its focus on Artin groups, where she has advanced theoretical frameworks through her thesis contributions and ongoing research as a visiting scholar. She maintains professional materials including her CV and research statement for academic dissemination.
