Prof. O'Sullivan has been a professor in the Geotechnics Section of the Department of Civil and Environmental Engineering at Imperial College since September 2017. She joined the Dept. in 2004 as a lecturer, following a two-year period at University College Dublin. She completed her PhD studies at the University of California, Berkeley in 2002. Her main research interest is in particulate soil mechanics. Her research uses discrete element modelling (DEM) as well as experimental techniques including micro-computed tomography (μCT). Catherine has been applying these techniques to look at fundamental sand behaviour, behaviour of reservoir sandstones, internal erosion and interpretation of laboratory tests.
Details of Catherine's book on Particulate Discrete Element Modelling can be found at: Particulate DEM: A geomechanics perspective. A Japanese language edition of Catherine's book on Particulate Discrete Element Modelling has been translated by Kiichi Suzuki.
Areas of Expertise:
Discrete element modelling, laboratory validation of discrete element models, development of discrete element analysis tools, micromechanics of granular material response, micro-computed tomography, characterisation of granular materials.
