Biography

I am currently an Associate Professor (Research) and UKRI Future Leaders Fellow in the Centre for Advanced Instrumentation, University of Durham, UK. Previous to this I worked as a postdoctoral fellow for two years at the Universidad Catolica, Chile. My research is concerned with forecasting, modelling, measuring and mitigating the Earth's atmospheric turbulence for applications such as astronomy and free-space optical communications. This has led to several novel instrumentation packages deployed at some of the world’s premier observatories and to many strong international collaborations.
