Research
  • Applying novel simulation techniques to improve our understanding of microstructural development during the processing of materials.
  • Coupling in-house developed models of the formation of solidification structures are coupled into microstructure-explicit constitutive equations of materials behaviour forming multiscale through-process models to predict the final properties of components.
  • Experimentally, my work focuses on developing in situ techniques to quantify the morphological changes and kinetics during phase changes from the meso to nano scales, in particular using x-ray radiography, micro-tomography (XMT), and STEM-HAADF tomography.

Biography
Professor Peter D. Lee joined Imperial College in 1994 after completing his D.Phil. in Materials Science from Oxford University. Prior to his doctoral studies on the solidification of aluminium, he was a Research Scientist at Alcan International's Kingston R&D Laboratory, where he helped established their Modelling of Shape Castings Programme, both developing analysis software and applying it to the design of many automotive castings. He is Fellow of the Institute of Materials, Minerals and Mining and a member of the Institute of Cast Metals Engineers, ASM International and TMS. He holds a B.A.Sc. in Engineering Science and M.A.Sc. in Materials from the University of Toronto, with his undergraduate and master's thesis focussing on the simulation of ferrous metallurgical processes.
