Postgraduate Researcher (Metamaterials CDT 2017)

I am currently a first year PhD student within the XM2 Metamaterials CDT at Exeter.

I previously graduated from Loughborough University in 2017 with an MPhys (Hons) in Physics. For my final project I investigated the spin Seebeck thermoelectric effect as a means of harvesting waste heat to produce useful electrical output. In particular, I focused on the efficiency of conversion between the applied heat flux and the power output, and how this could be improved using multilayer thin film structures.

For my current project within the CDT, supervised by Dr David Horsell and Prof. Alastair Hibbins, I am investigating micro-acoustic arrays for active sound control. The initial focus of this project is to explore thermoacoustic sound generation and how its efficiency can be maximised through choice of material parameters, as well as device structure.
