Summary

 

Summary

I am a Lecturer and EPSRC Early Career Fellow at Imperial College London, working on the environmental degradation of engineering alloys. I have a particular interest in oxidation and hot corrosion of nickel and cobalt-based superalloys as well as advanced characterisation techniques such as transmission electron microscopy (TEM) and atom probe tomography (APT). I teach the 1st year undergraduate module in Materials Electrochemistry MSE104. 

Current research projects: I have a long-standing research collaboration with Rolls-Royce plc, who are co-sponsoring several PhD studentships, including several that I am about to advertise. I have some collaboration projects with Knauf Insulation and CCFE. The topic is always environmental degradation of various engineering alloys/oxides/coatings. If interested, please contact me.
