Summary
Dr Stella Pedrazzini is a Lecturer in Engineering Alloys and Metallurgy, EPSRC Early Career Fellow and RAEng Associate Research Fellow at Imperial College London.
She works on the environmental degradation of engineering alloys, with a particular interest in oxidation and hot corrosion of nickel and cobalt-based superalloys, aqueous corrosion of steel as well as advanced characterisation techniques such as transmission electron microscopy (TEM) and atom probe tomography (APT). She teaches the 1st year undergraduate Origins module (Metals Extraction) and the 3rd year Superalloys course.
