Staff Profile

Summary

I am a Royal Academy of Engineering Research Fellow, Senior Lecturer, and Head of Research in Chemical Engineering, and in 2025 I was the recipient of the IChemE Warner Medal.

Currently, I am Research Lead in a ~£12M EPSRC Centre for Doctoral Training, Work Package Lead in a ~£9M EPSRC Programme Grant, and CoI in a ~£2.5M EPSRC Standard Grant (see Research Tab for more details).

My main research interest is in gas separation processes (using sorbents and membranes), typically applied to carbon dioxide capture, utilisation, and storage (CCUS), and direct air capture (DAC). I currently supervise 7 PhD students and 3 post-doctoral researchers in these areas, spanning materials and process development, to energy systems integration and life-cycle assessment.

My teaching responsibilities include modules related to chemistry, materials science, sustainability, and carbon dioxide capture (see Teaching Tab for more details).

More widely, I work across academia, industry, finance, politics, and the third sector on projects spanning research, education, technical consultancy, due diligence, policy development, and public engagement. If you are interested in working with me in any capacity please don't hesitate to get in touch using the email address above, or connect with me on LinkedIn.
