Research interest: My research seeks to elucidate exotic states of matter using laser-optical approaches.
In particular, topologically non-trivial electronic states may enable novel functionalities that could revolutionize a wide range of applications including next-generation spintronics, energy applications, or quantum computing. A special focus of my current work is to investigate the interaction between topologically non-trivial electronic states and magnetism, which may enable new magneto-electric coupling phenomena for energy-efficient spintronic devices.
