Key details
Dr Andrew Kao
Associate Professor in Applied Mathematics
Andrew was awarded a BSc in Physics from Imperial College London in 2005, followed by an MSc in Computational Science and Engineering at the University of Greenwich and progressing onto the PhD programme. His PhD titled 'Thermoelectric Magnetohydrodynamics in Dendritic Solidification' was completed in 2010. He is now an active researcher as part of the Computational Science and Engineering Group.
His research focuses on numerical modelling of the effects of magnetic fields and fluid flow on the evolution of alloy microstructures. He leads the development of the ThermoElectric Solidification Algorithm (TESA), a parallelised code that solves the coupled problem of microstructure solidification, electromagnetism and fluid flow. TESA has been used in a wide range of applications including defect formation in turbine blade casting, additive manufacturing processes and highly undercooled growth.
