Research Interests

Selma's field of research interests focuses on the design, implementation, electrical characterization, preparation, and instrumental analysis of samples. She has expertise in Condensed Matter Physics, Materials Physics, and Materials Science.​ ​Her project will extend the understanding of the spin-dependent thermal and electrical transport in MTJs, and demonstrate that thermoelectric power can be used as a characterization of the heating/cooling dynamics in MTJs.
