### About

I am a PhD student at UNSW, Sydney, working under the supervision of Gary Froyland.

My research is concerned with the statistical properties of autonomous and non-autonomous dynamical systems, and, in particular, how such properties behave under perturbations (e.g. to the dynamical system, or as a result of numeric approximation). I am interested in how these questions may be answered using functional analytic and spectral methods.
