Biography

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.

I am currently a lecturer for the 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.

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.
