I am a Ph.D. student in a sustainability research project "Green Steel for a Fossil-free Future" funded by the EU and Tillväxtverket. My work aims to provide deeper insight into the hydrogen embrittlement problem of steel and develop mitigation strategies through steel designs. This meets the ongoing trends towards a more hydrogen-based economy for our society and industry.

My current research focuses on understanding the duality of hydrogen i.e. strengthening and embrittlement behaviors in Fe-Cr-Ni-based austenitic stainless steel. The use of atom probe tomography (APT) will be of great assistance in visually characterizing the distribution of hydrogen in steels. The study will deepen the understanding of the roles of hydrogen on the steel's mechanical properties in link to the evolution of different microstructures and provide insight into effective steel designs against hydrogen embrittlement.
