About me

I am currently a European & UK Patent Attorney at Kilburn & Strode LLP.

From 2013 to 2014, I was a Research Scientist under the joint supervision of Dr Patrick Naylor (Imperial College London, UK) and Prof Emanuël Habets (International Audio Laboratories Erlangen, Germany).

In 2013, I completed a PhD in the Speech and Audio Processing group of the Department of Electrical & Electronic Engineering at Imperial College London, supervised by Dr Patrick Naylor.

My research is in the field of spherical microphone arrays and their application to acoustic parameter estimation and speech enhancement. I am also interested in languages, all things Mac, and photography (London weather permitting).
