Seanís research focuses on spatially resolved spectroscopy and spectroscopic tomography in the electron microscope. Projects include work on a range of materials from oxide nanoparticles in catalysis to metal-organic framework glasses.
Following post-doctoral work in the group, Sean is the Henslow Research Fellow at Girton College (from October 2017).
Seanís PhD work in the Electron Microscopy Group developed the use of scanning transmission electron microscopy and electron energy loss spectroscopy (STEM-EELS) for the characterization of optical properties of metal nanoparticles, including the experimental realization of quantitative surface plasmon tomography as well as 2D analysis of surface plasmon resonances in silver and gold particles and particle ensembles. Sean completed his PhD at Trinity College, Cambridge as a Gates Cambridge Scholar and was an Associate of the EPSRC CDT in Nanoscience and Nanotechnology (NanoDTC).
