Dr Rodenburg was awarded a Royal Society Dorothy Hodgkin Fellowship entitled "Applications of MEMS electrostatic manipulation in SEM and materials science" which she took up in 2006, and after a brief spell as University teacher, now holds an EPSRC Early Career Fellowship and is a Senior Lecturer in Materials Science & Engineering.

Research

Current research interests:

My research is centered on the use of electrons and ions for the characterisation and modification of micro-and nanostructured materials. This includes the development and application of novel characterisation techniques, alongside the study of damage and charging phenomena for targeted materials properties modification and transport. Recent key projects include:

  • Nano-morphology of polymer blends for organic photovoltaics (collaboration with Trinity College Dublin and UoS Department of Physics)
  • Novel Polymer composites for Additive manufacturing (collaboration with UoS Mechanical Engineering (Advanced Additive Manufacturing Group))
  • Secondary electron spectroscopy in the scanning electron microscope (collaboration with FEI company) and EPSRC funded project. Read more
  • Characterisation of Natural materials

Previous research interests:

  • The role of the substrate/coating interface of ceramic hard coatings for dry high speed cutting applications
  • Influence of carbide distributions on properties and wear of high speed steels
