Summary

Dr. Iasmi Sterianou joined Sheffield Hallam University in 2013 as a Lecturer in Materials Engineering and became a Senior Lecturer in 2016. Her main research expertise is the development of novel functional materials. Iasmi teaches on a number of topics in Materials Engineering and Chemical Engineering courses and is the Course Leader for the FdEng/BEng (Top-up) Materials Engineering courses since 2016.

  • About

    Iasmi received her MEng in Chemical Engineering from the Aristotle University of Thessaloniki, Greece, in 2003, after completing her dissertation on Molecular Beam Epitaxy and its Application on High-Temperature Superconductors. She then did research on bismuth-based perovskites for high temperature piezoelectric applications and received her PhD in Engineering Materials from the University of Sheffield in 2008. Upon completing her PhD, she became a Postdoctoral Research Associate at the University of Sheffield working in advanced functional oxides.
