Research overview

My research interests are in the study of materials and surfaces with atomic and sub-molecular resolution.  We aim to measure and understand the interactions between single atoms and molecules on surfaces, and exploit this knowledge to push the limits of atomic scale imaging, chemical mapping, 2D molecular self-assembly, on-surface catalysis (single atom chemistry), electrochemistry and atomic manipulation and single molecule measurement. 

We use a variety of methods to pursue these goals, including atomic resolution atomic force microscopy (AFM), scanning tunnelling microscopy (STM) and spectroscopy, theoretical ab initio electronic structure calculations, XPS, IR spectroscopy and x-ray standing wave studies at the national Diamond Light Source synchrotron facility.

Supporting this work I run the Nanoscale Materials Microscopy pod in our ultra-low-noise IsoLab facility (www.lancaster.ac.uk/isolab), dedicated to ultra-sensitive measurements and characterisation of nano and molecular structures. 

 

PhD supervision

Competitively funded projects are available in the areas of: 1) Single molecule properties on surfaces. 2) Directed assembly of 2D molecular structures. 3) Scanning probe microscopy in ultra-low noise environments. 4) Computational simulation of molecular properties. 5) Synchrotron radiation studies of surface structure. Please contact me if you are interested in working on a PhD project. We are always happy to hear from enthusiastic students. Funding, where available, will be awarded on a competitive basis. Current projects include "Atomically precise materials for separation and storage" and "Correlating atomic-scale defects to 2D material properties for quantum security applications".

Professional Role

Lecturer in Nanoscale Characterisation.

Career Details

I am a 50th Anniversary Lecturer in Nanoscale Materials Characterisation in the Physics Department and Materials Science Institute at Lancaster University.  Prior to this I worked in the University of Nottingham Nanoscience group. 

In 2013 I was awarded the IOP Albert Franks prize for best PhD thesis in nanoscience and in 2014 the Young Scientist prize at the 11th International Conference on the Structure of Surfaces (ICSOS). Since completing my PhD I have been awarded two independent fellowships, an EPSRC Doctoral Prize in 2013 and a Leverhulme Early Career Fellowship in 2015, which helped me secure a lectureship position at Lancaster University early in my career. 

My research is currently supported by grants from the Royal Society, EPSRC, The Leverhulme Trust and the Medical Research Council.

Current Research

1) Single molecule properties on surfaces.

We study the properties of single molecules gaining fascinating insights into electronic, structural and mechanical properties of materials at the fundamental level. 

2) Directed assembly of 2D molecular structures. 

The directed assembly of single molecule precursors into larger 2D networks provides a route for fabricating functional molecular structures with tailored properties.  

3) Scanning probe microscopy in ultra-low noise environments. 

With microscopes housed in Lancaster University’s new £2M ultra-low noise Isolab facility we are pushing the limits of imaging and force measurement with SPM.  

4) Computational simulation on high end computing systems. 

Quantum mechanical simulation of atomic structure is a powerful tool for understanding crystal and molecular properties.  

5) Synchrotron radiation studies of surface structure.

Structural and electronic properties of surface materials using synchrotron radiation (e.g. x-ray photoelectron spectroscopy (XPS), normal incidence x-ray standing wave spectroscopy (NIXSW)).
