Biography

Dr. Lee A. Fielding obtained a MChem in Chemistry with first class honours from The University of Sheffield in 2008, which was followed by a PhD in 2012 on the synthesis, characterization and applications of colloidal nanocomposite particles from the same institution with Professor Steven P. Armes.
Dr. Fielding then worked as a Postdoctoral Researcher on the preparation of bespoke colloidal particles via RAFT dispersion polymerization, in part for occlusion within inorganic host crystals. He has conducted research in several other areas of polymer and colloid science including the preparation of polymer brushes, as well as synthetic micrometeorite analogues.
He took up a Lectureship in the School of Materials at The University of Manchester in September 2015.

Research Interests

  • Preparation of colloidal nanoparticles/nanocomposites via controlled radical dispersion or emulsion polymerisation.
  • Characterisation of such particles using techniques such as dynamic light scattering, disc centrifuge photosedimentometry, transmission electron microscopy and small-angle X-ray scattering.
  • Investigation into the potential applications of these particles (e.g. for biomineralisation studies or as functional coatings).
  • Other interests include deposition of conducting polymers onto various templates, synthesis of polymer brushes and preparation of Pickering emulsions and colloidosomes.
