Biography

I am a Senior Lecturer for the James Watt School of Engineering and a member of the Glasgow Computational Engineering Centre (https://www.gla.ac.uk/research/az/gcec/), a subgroup of the Infrastructure and Environment Research Division.

I graduated with a BEng in Civil Engineering from Swansea University in 2007, followed by a PhD from the same institution. My PhD focused on the proof-of-concept development of a new system of first order conservation laws for computational solid dynamics (http://ukacm.org/wp-content/uploads/phdThesis/2012_CHLee.pdf). After graduating in 2012, I joined the EU funded “ASTUTE” project. In 2015, I was appointed as a Ser Cymru Research Fellow of the Zienkiewicz Centre for Computational Engineering at Swansea University.

Research Interest

My research interests are in computational mechanics, with special emphasis on the development, analysis and application of non-conventional computational methods for large strain fast solid dynamics. Specifically, a new computational paradigm is established on the basis of a new set of physical laws. These laws can be re-formulated as a system of first order conservation laws, with a similar structure to the mathematical equations used in CFD. The new approach lays the foundation for a unified modelling of multiple physics problems, including thermo-elasticity, fluid structure interaction and electromechanics. I am also interested in developing new computational methods for modelling of protection systems subjected to hyper-velocity impact. The applications include high strain rate material failure, gas pipe explosions/implosions and spacecraft shielding.
