I am developing a gas sensor to selectively measure volatile organic compounds (VOCs) for indoor air quality and health monitoring applications. Standard methods of measuring VOCs use analytical laboratory equipment (e.g. gas chromatographs), but such techniques are large, expensive and require expertise to use. This project seeks to create a novel sensor that addresses these limitations, by combining low-cost air quality sensors with ‘on-sensor’ gas separation. Products using this technology could be used to measure the air quality of working, educational and residential environments, and pave the way for accessible health diagnostics. The project is a collaboration with Alphasense Ltd.

I am a member of the Sensor CDT at the University of Cambridge, through which I have completed an MRes degree in Sensor Technologies. Previously, I completed my MSci in Chemistry at the University of Bristol.
