Biography
I was a research assistant at the Paul Scherrer Institute in Switzerland, where I investigated current-induced domain wall motion in nanomagnetic devices. After receiving a doctorate in physics (Dr. rer. nat.) from the University of Konstanz in Germany, I worked as a postdoctoral associate in the group of Prof. Andrew Kent at New York University. There I developed magnetic multilayers for spin-transfer torque random access memory (STT-MRAM) devices and developed a fabrication process for spin torque nano oscillators (STNO). As of March 2014, I am a postdoctoral research associate in the Semiconductor Physics group at the University of Cambridge. I am studying transport in the presence of disorder in mesoscopic 2-dimensional electron systems based on GaAs/AlGaAs-heterostructures. This work is carried out in collaboration with Prof. Mike Pepper from UCL in London.
Research
My current research interest is in topological insulators. For the future, l would like to harvest the unique properties of topological transport for spintronic applications and to demonstrate functional hybrid topological insulator/spintronic devices.
