Research Interests

My research focuses on the crystal growth and synthesis of functional and quantum materials. I am particularly interested in topological magnetic materials that host exotic spin textures, unconventional superconductors with noncentrosymmetric or kagome structures that exhibit unusual superconducting behaviours, and frustrated magnetic systems that are potential hosts of quantum spin-liquid states. I employ a wide range of advanced characterisation techniques to develop a comprehensive understanding of the complex magnetic and superconducting properties of these quantum materials.

Areas of Research:

Topological Magnetism

Following the discovery of magnetic skyrmions in 2009, research into topological magnetism has expanded rapidly, leading to the realisation of a wide variety of complex topological spin textures. Remarkably, skyrmion-like spin structures have now been observed in materials that lack the Dzyaloshinskii–Moriya interaction, indicating that alternative stabilisation mechanisms must be at play. This has opened up exciting new possibilities for discovering and engineering topological magnetic states.

We synthesise single crystals of these materials and investigate their complex magnetic phase diagrams using neutron diffraction, resonant X-ray scattering, and muon spectroscopy.

Unconventional Superconductors

In unconventional superconductors, superconductivity cannot be fully explained by Bardeen–Cooper–Schrieffer (BCS) theory. These materials exhibit unusual behaviours such as high superconducting transition temperatures, exotic gap symmetries, and time-reversal symmetry breaking.

We synthesise novel superconductors and investigate their physical properties using muon spectroscopy and heat capacity measurements.

Frustrated Magnetism

Frustrated magnetism is a phenomenon in which the spins in a magnetic material cannot align in a configuration that minimises the system’s energy. This frustration may arise due to the geometry of the crystal lattice—such as triangular or kagome arrangements—or from competing interactions between magnetic moments. As a result, these systems often exhibit highly degenerate ground states and can host exotic emergent phases, such as spin liquids and spin ices.

We synthesise large, high-quality single crystals of these systems. We then Use elastic and inelastic neutron scattering techniques to gain insights into the nature of frustration and the emergent quantum phenomena that arise from it.

Research Techniques:

Single Crystal Growth

To fully understand and exploit the intrinsic physics of materials, the study of high-quality single crystals is essential. My research focuses on the synthesis of single-crystal quantum materials using a wide range of advanced growth techniques. These include the optical floating zone technique, chemical vapour transport, the Bridgman technique, the self-flux method, and the Czochralski technique. We are constantly developing and evolving to improve the quality of crystals we can grow.

Neutron Scattering

Neutron scattering is one of the most powerful techniques for probing the atomic and magnetic structures of materials. Neutrons are neutral particles, allowing them to penetrate deeply into matter, yet they possess a magnetic moment due to their intrinsic spin. This unique combination enables neutrons to interact with magnetic moments. Using neutron diffraction, we are able to determine the complex magnetic structures present in the materials we synthesise.

Muon Spectroscopy

Muons are a powerful tool to investigate material properties such as fundamental magnetism, superconductivity and functional materials. Using muon spectroscopy we can determine the superconducting gap structure, search for time-reversal symmetry breaking in superconductors and to explore the complex magnetism in the materials we synthesis.

My Background

Since 2024 I have been an academic in the Department of Physics at the University of Warwick as part of the Superconductivity and Magnetism group. Prior to this I worked as a Research Fellow working jointly with Prof. Geetha Balakrishnan, Prof. Martin Lees, Dr Oleg Petrenko and Prof. Paul Goddard on a broad range research projects. I joined the Superconductivity and Magnetism group at the University of Warwick in 2019 as a Research Fellow, where I worked with Prof. Geetha Balakrishnan, as a part of The Skyrmion Project until winter 2021. I undertook my PhD at the University of Warwick under the supervision of Prof. Martin Lees. I had previously completed my MPhys Physics degree at the University of St Andrews in 2015.

In addition, I am the staff contact for the NMR experiment (P3) within the second-year teaching laboratory (PX271).

I was honoured to be selected as a commendee for the Warwick Awards for Teaching Excellence for Postgraduates who Teach 2018.

Public Engagement, Outreach and Widening Participation

I help run a series of workshops on superconducting 'levitation'. As part of this program, I deliver the workshops at the University of Warwick, local schools and at science events.
