Research Overview
I enjoy working on problems at the intersection of theory and practice. My interests include language design, (probabilisitc) semantics, compilers, automata theory, formal verification, and algorithms.
I am passionately working on making networks more programmable.
Before coming to Cornell, I received a B.Sc. in Computer Science from Technische Universität München, where I worked with Jasmin Blanchette on the interactive theorem prover Isabelle.
