Profile

I am Senior Lecturer in the School of Chemical, Materials and Biological Engineering, where I lead the (SMASH) research team.

I am Postgraduate Research Lead for the School of Chemical, Materials and Biological Engineering, and Deputy Head of the Engineering Graduate School for the Faculty of Engineering. I am also the UoS-Director of the EPSRC Centre for Doctoral Training SATURN (Skills and Training Underpinning a Renaissance in Nuclear, 2024-2032), and am Editor for

My research has been funded by the Engineering and Physical Sciences Research Council (EPSRC), Innovate UK, Department for Business, Energy & Industrial Strategy, Department for Energy Security and Net Zero, Nuclear Decommissioning Authority, Sellafield Ltd., National Nuclear Laboratory, and both UK and international industry groups.

I teach a variety of research-led core and applied chemical engineering subjects. I was awarded the ‘Outstanding PGR Supervision Award’ in each of the past three, an ‘Undergraduate Teaching Award’ in 2020, and received a ‘Letter of Commendation for Teaching Excellence’ in 2019 from the Department of Chemical and Biological Engineering, ��«Ӱҵ.

Research interests

My research aims to drive new advances in the development of materials and processes for sustainable infrastructure, environmental remediation, waste management, and clean energy. This will enable industry to meet the needs of our society both sustainably and cost-effectively, improving the well-being of our society and environment.
Broadly speaking, our research group focuses on investigation of composition-structure-property relationships, reaction mechanisms and kinetics, and surface chemistry in cements, glasses, ceramics and nanomaterials using advanced spectroscopic and microstructural techniques. We also explore new approaches to study resource production and consumption, decarbonisation strategies, and cross-sector interactions affecting this.

Current projects focus on:

Development of low-CO2 cements for sustainable infrastructure
Understanding durability and degradation phenomena in low-CO2 cements
Development of materials for encapsulation/immobilisation of radioactive waste
Understanding and controlling radionuclide-cement interactions in cement matrices used for immobilisation of radioactive waste
Understanding mass transport processes in cements for applications in both construction and nuclear sectors
Development and assessment of decarbonisation strategies for construction and the built environment
