About me

I'm a VR postdoc fellow working in the group of Assoc. Prof. Yasmine Sassa.
My research is focused on exploring the emergence of novel topological chiral spin configurations in low dimensional magnets. I work on designing new spin structures beyond traditional magnetic skyrmions, arising from interface engineering of multilayers to alter the interfacial magnetic properties and tuning the static and dynamic behaviors of skyrmions. By growing multilayers based on transition metal compounds and controlling the growth at the atomic scale, I explore how interfaces influence the magnetic and electronic properties of systems. The emerging field of atomic-scale interface engineering for skyrmion systems are essential for practical applications like memory devices and quantum computers.

I obtained my PhD on 13th December 2024 in Materials Science from Thin Film Physics Division, Linköping University. During my PhD study, I could develop a technique to grow high-quality heteroepitaxial superlattices from constituents with incompatible growth conditions by magnetron sputtering, a complex challenge that demanded precision, innovation, and long-term perseverance. Superlattice structures are popular in a broad range of applications such as electronic, magnetic, optical, and hard coating. The scientific challenges during my research taught me not only nano-engineering of heterostructure superlattices but also revealed similarities between the behaviour of atoms and humans and how to reach harmony through strategic solutions while respecting the differences. Working with billions of atoms, I learnt that trying to make changes forcefully will lead to nothing but chaos.
I believe PhD study is not only about obtaining a degree and being specialized in a certain scientific field. It shapes the way we think, communicate, and lead. It teaches us how to persist in the face of uncertainty, to focus on what can be done rather than on perceived limitations, and to stay aligned with our goals even when the path is difficult.

Research Grants and Scholarships:

I received 10 grants and scholarships for different purposes such as interdisciplinary work, attending conferences, initiating international collaborations, research stays abroad, and experiments at large-scale facilities from SVCF (Society of Vacuum Coaters Foundation), Hans Werthénfondens (The Royal Swedish Academy of Engineering Sciences, IVA), Lars Hiertas Minne, ÅForsk, Medard W. Welch Award (IUVSTA), KVA (The Royal Swedish Academy of Sciences), etc.

Experience at Large-Scale Facilities:

Being a PhD student at Swedish Neutron Graduate School (SwedNess), I’ve been to different large-scale neutron facilities such as PSI in Switzerland, TU Delft in Netherland, ILL in France, ISIS in the UK, J-PARC in Japan, for hands-on trainings, beamtimes, extended stay, etc. I’ve been the PI for 5 successful beamtime proposals at both Neutron and Synchrotron sources during my PhD study. Neutron Reflectometry and Grazing-incidence small-angle X-ray/Neutron scattering are the main techniques that I use for my research in addition to in-house characterization techniques.

I served as the student representative in the board of Swedish Neutron Scattering Society from 2023 to June 2025.
