Research
My research focuses on image and data analysis, physical modelling, numerical optimisation, and reproducible scientific software.
Research profile
I completed a PhD at the University of Iceland in 2021. My doctoral research focused on computational reconstruction and analysis of three-dimensional atomic structures of metal nanoclusters from aberration-corrected scanning transmission electron microscopy data.
