I am a postdoc at UPV/EHU in Bilbao working on geometric group theory.  My work focuses on generalizations of hyperbolicity, including acylindrical and hierarchical hyperbolicity. I am particularly interested in Artin groups. 

I received my PhD from Brandeis University in August of 2025. My supervisor was Carolyn Abbott. My thesis constructs an analogue of the marking graph, originally defined for surfaces, for finite-type Artin groups. It also contains a background section which provides a gentle introduction to combinatorial hierarchical hyperbolicity for readers familiar with the mapping class group. It is available here.

My CV is available here, and my research statement is available here.
