Research

My interests span a wide range of topics in physical metallurgy, including phase transformations, alloy design and alloy characterisation.  I'm currently working on a number of projects, in which I'm using high-resolution TEM techniques (STEM, EDX, diffraction) to characterise precipitates in alloys and understand their formation.  

My PhD examined the segregation that can occur over macroscopic distances during the solidification of large alloy castings, so I also have an interest in aspects of process metallurgy and solidification, including: fluid flow in castings, channel formation (freckling and A-segregation) and macrosegregation phenomena.
