My research is based around the novel fabrication and function of electromagnetic metamaterials. This means that I look to make these materials in new ways, demonstrate new effects and use them for new applications. 

Some of the key areas I am interested in currently are:

  • Broadband metamaterials based on interlaced meshes.
  • Self-folding, (or shape morphing) materials based on origami or kirigami concepts.
  • Materials with extraordinary electromagnetic scattering behaviours for radar detection/deception and antenna design.
  • Metamaterials for RFID and lnternet of Things.
  • Fabrication of metamaterials using additive manufacturing and 3D weaving.

If you would like to know more about my work then please feel free to drop me an email. 

I am a member of Exeter's Centre of Metamaterials Research and Innovation and the associated doctoral training centre for PhD students.

If you are interested in undertaking a PhD with me or one of our other academics, please see here for a list of opportunities, and get in touch or apply now.

I am also a member of the leadership team for the UK Metamaterials Network, which is a community of over 600 university academics, and industry and governmenal scientists and engineers. If you are a student, postdoc, academic or industry employee, please join our community and engage with our events and activities.
