Associate Professor in the Department of Physics

What do you do?

I am a condensed matter physicist working at Durham University. My research spans condensed matter physics, solid state and materials chemistry, focusing on understanding structure – property relationships in a range of complex materials, and on the design and synthesis of functional materials. 

How are you involved in this area of science? 

Whether it’s designing semiconductors with structures of specific symmetries for solar cell applications, or materials with key magnetic and dielectric properties for electronic and data storage applications, our group combines insight from experimental and computational approaches.

We make new materials, sometimes guided by computational results, investigate their structures (e.g. using diffraction techniques), measure their physical properties (e.g. magnetism, conductivity, photoactivity), and use computational methods to help explain these experimental results. This understanding helps us design new, optimised, functional materials. 

What do you love about this topic?

I love making a material that has never been reported before, understanding how its atoms are arranged and how that determines its physical properties. This research involves using a number of techniques – sometimes through collaboration, and it’s great to be able to work alongside some amazing people. 

How does this work deliver real-world impact?

New technologies require functional materials with new combinations of properties – whether its semiconductors that are polar for solar cell applications, or unusual combinations of magnetic, dielectric and chiral behaviours for spintronics, or data storage. We can only meet the demands of emerging technologies if we understand these complex physical properties, and how to design materials to exploit these behaviours.
