Research areas of interest include:
- Environmental monitoring
- Functionalised nanomaterials
- Atomic layer deposition
My group works on the development and application of materials to tackle problems in the fields of environmental monitoring, catalysis and energy. The materials approach we use is to leverage vapour deposition techniques (chemical vapoour deposition, atomic layer deposition) to provide direct integration of (functionalised) nanomaterials with devices and to allow new device fabrication strategies. This work is cross-disciplinary and application led, involving close collaboration with both academic and industrial partners and with stakeholders to deliver and evaluate the research.
Recent research has focussed on the use of aerosol-assisted chemical vapour deposition for synthesis of metal nanoparticle functionalised metal oxide nanostructures for use in sensitive and selective chemoresistive sensors. The use of this technique has advantages over other methods of integrating nanomaterials and devices of having fewer processing steps, relatively low processing temperature,and no requirement for substrate pre-treatment.
In addition this provides advantages in utilising nanomaterials on low power microelectromechanical systems (MEMS) substrates, where fabrication can be difficult using conventional techniques.
Further, by simple modification of the process a family of nanosensors can be produced allowing quantative detection of mixtures of gases via a sensor array.
We are interested in applying a range of vapour deposited functionalised nanomaterials in a range of catalytic applications, tested in collaboration with partners in Chemical Engineering and at Imperial College.
Our principal interests are in extending the range of metal nanoparticles we can synthesise, investigating parameters that control the size and dispersity of these particles and also the range of support materials we can utilise.
Results are currently at an early stage but demonstrate extremely promising selectvity in test reactions and application in microcatalysis is being investigated.
Our group is working on a range of materials and applications, from photoelectrochemical and photocatalytic water splitting, CO2 utlisation via photocatalysis and battery electrodes.
all of these applications we are interested in the application of new
nanomaterials and/or new device fabrication strategies, for instance
opportunities afforded by atomic layer deposition of ultra-thin
conformal coatings in water splitting and in metal nanoparticle
plasmonic enhancement of visible light semiconductor photocatalysis.
Recent research on the use of CVD for the deposition of composite thin films composed of bismuth oxide and platinum nanoparticles has been featured in a“Young Investigators Award” issue of Inorganica Chimica Acta.

My interests are in the use of web-based resources for enhancing learning outcomes from traditional methods of teaching at university level. This work has recently been acknowledged via a prestigious Provosts Teaching Award at UCL.
Recently I have been exploring the use of video lectures to create a virtual library to support postgraduate teaching and I have also been working with a software developer (Learnexx 3D) to develop 3D virtual lab simulations to be used in pre-lab preparation. A demo of the software can be found in the following link to the Learnexx simulation
This work has been supported by a variety of grants including, most recently, funding from UCL:
Enhancing the Chemistry programme using Virtual Learning Environments (VLE)
Developing web-based prelab tutorial support for teaching in the chemistry laboratory
