I am an Assistant Professor in the mathematics department at the University of Massachusetts Boston.
I study symplectic and contact geometry, using techniques from geometric topology, category theory, homotopy theory, and dynamical systems. My research focuses on unifying symplectic flexibility and h-principles
with rigidity and Floer theory, leading to new structural results for the Fukaya category and connections to algebraic K-theory, Anosov dynamical systems, and rational homotopy theory.
