Open vacancies

The funded PhD and Masters places in my group have now been allocated, however opportunities still exist for self-funding PhD students.  Please get in touch if interested.


My research concerns the fabrication, processing, characterisation and modelling of low-dimensional materials, including metal oxide nanowires and nanosheets, and graphene. I also design, characterise and model novel electronic devices, particularly those that make use of low-dimensional physical properties, or suffer from confinement or leakage issues due to small sizes. See for example http://dx.doi.org/10.1021/nl503743t or http://dx.doi.org/10.1088/0957-4484/26/41/415701

Working within the Centre for Nanohealth at Swansea we are able to fabricate a wide range of nanomaterials. Our characterisation equipment includes ultra high vacuum four point probe (with in-situ scanning electron microscopy), scanning auger microscopy, and x-ray photoelectron spectroscopy.

I have supervised many PhD, masters, and other research students on these areas – some are listed below. Interested potential students are welcome to email for a current list of vacancies.

In 2007 I was awarded a Royal Academy of Engineering Research Fellowship to model scanning probe measurements of electronic devices. My research has been funded by the Royal Academy of Engineering, EPSRC and A4B (Welsh Government/EU).

I’ve given many invited public engagement talks on nanotechnology including at the Swansea Science Café, the University of the Third Age, the Royal Society of Chemistry and an IET ‘Living History’ event.

I also have a postgraduate qualification in higher education teaching (PGCTHE), am a Fellow of the Higher Education Academy, a member of the Institute of Engineering and Technology and am a member of the Institute of Physics. I am currently the Level One co-ordinator for Electronic and Electrical Engineering.
