PhD in Physics, University of Swansea 2019

BSc in Physics, University of Swansea 2015


After completing his BSc Physics with Nanotechnology at Swansea University, Liam moved onto a PhD project in the Centre for Nanohealth at Swansea. His PhD was an industrial linked project through the pan-Wales KESS initiative, where Liam worked with Siemens Healthineers to carry out characterisation of raw materials utilised in manufacturing commercial immunoassays. Raman spectroscopy was the primary tool of use, with FTIR spectroscopy also used to reinforce observations made.

In 2019 he joined Dr Goldberg Oppenheimer's group to carry out research related to TBI, focussing on open science and the development of research tools for clinical applications. During this time Liam received the Innovate ICURe grant and travelled internationally for 3-months in investigate commercialisation of spectroscopy devices in healthcare settings.

In 2021 Liam moved to the IGI to work alongside Prof Stefan Krause and colleagues to work on the collection and characterisation of nano and microplastics, in water, soil, air and biological samples. This further extends to developments of Raman devices for lab and field use and more advanced methods for detection of the smaller size fractions of microplastics.


Liam has a background in experimental physics working on spectroscopy systems for the characterisation of both biological and non-biological samples. He has been focused on work with multidisciplinary aspects and translation into wider settings outside of the university.

Primarily his work now focused on the use and analysis of Raman spectroscopy with research including:

  • Low-cost spectrometer design, for a cheaper and more affordable system to be used in a variety of settings.

  • Developing tools for improved analysis of spectral data.

  • Transferring novel spectroscopy methods into broader fields of application.
