I am a Hill Assistant Professor at Rutgers University, where my mentors are Henryk Iwaniec and Alex Kontorovich. I am principally interested in objects at the intersection of the geometry, arithmetic and dynamics of discrete subgroups of SL(2,R). I received my PhD in June 2016 from ETH Zürich. My advisor was Alessandra Iozzi.
