Dr Shelly Conroy is a Royal Society University Research Fellow, specialising in in-situ transmission electron microscopy (TEM) and electron spectroscopy (EELS). She worked at Pacific Northwest National Laboratory as a permanent staff scientist before joining the University of Limerick as a Science Foundation Ireland Analog Devices Research Fellow (PI). Dr Conroy holds a PhD in GaN thin film growth and in-situ TEM from Tyndall National Institute.

Dr Conroy’s URF grant ‘Improper Ferroelectric Domain Wall Engineering for Dynamic Electronics’ is focused on thin film growth of the ferroelectric/ferroelastic boracites and in-situ 4DSTEM strain analysis. The project is in collaboration with the National Center for Electron Microscopy at Lawrence Berkeley National Laboratory and SuperSTEM the EPSRC National Research Facility for Advanced Electron Microscopy. 

In 2019 Dr. Conroy was awarded an SFI Industry Research PI grant with Analog Devices; ‘Dynamic Atomic Interface Characterisation for Improved Performance of Electrical and Magnetic Devices’. Shelly investigated magnetoresistance devices based on dynamic magnetic domain walls via real time MOKE and differential phase contrast STEM while applying bias and heat. 

At the University of Limerick Dr. Conroy was also working on the NSF/SFI funded US Ireland Conducting Domain Walls for Novel Nano-Electronics’ project within Prof. Ursel Bangert’s (PI on grant) group. Here she investigated ferroelectric domain wall structure at the atomic scale by aberration corrected STEM and probing their band structure via electron spectroscopy. She used in-situ heating and biasing TEM to investigate the dynamic changes at these boundaries. This project was in collaboration with Prof Marty Gregg’s group at Queens University at Belfast and Prof Alexei Gruverman’s group at University of Nebraska-Lincoln. 

Dr Conroy was a postdoctoral researcher at Pacific Northwest National Laboratory within the DOE Nuclear Processing Science Initiative. She focused her research on high resolution and in-situ electron microscopy techniques including STEM EDS, EELS, thermal annealing, liquid cell and cryo. She was promoted to permanent staff scientist in 2017 within the Energy and Environment Directorate.
