Hello! I’m an assistant professor at the Brandeis mathematics department, where I am grateful to hold the Berger-Leighton junior chair. I am also grateful for the support of the National Science Foundation under grant DMS-2203455.
My research is in symplectic and contact topology. I am particularly interested in the flexible side of the field as well as in the connections with parametrized Morse theory, algebraic K-theory and singularity theory.
