About

I am an experimental physicist working at the interface between condensed matter physics, materials science and nanodevice engineering. My research focuses on how spin, orbital and topological degrees of freedom can be generated, detected and controlled in quantum materials and thin-film heterostructures.

My work combines material growth and device fabrication with advanced electrical, magnetic, microwave and optical characterization methods, including ferromagnetic resonance, spin pumping, magnetotransport, magneto-optical Kerr effect, XMCD and synchrotron-based spectroscopy.

Research

My research aims to understand and exploit angular-momentum conversion, magnetization dynamics and topology-driven electronic phenomena in functional materials and heterostructures.

Spin and orbital transport

Electrical and microwave detection of spin-charge and orbital-charge conversion in quantum materials, oxides and low-dimensional systems.

Topological quantum materials

Thin-film heterostructures based on topological insulators, semimetals and symmetry-protected materials for spintronic and orbitronic functionalities.

Magnetization dynamics

Ferromagnetic resonance, spin pumping, damping engineering and microwave spectroscopy in magnetic multilayers and functional interfaces.

Magneto-optical detection

High-sensitivity MOKE approaches for detecting current-induced spin accumulation, magnetic dynamics and interfacial spin-orbit effects.

Oxide electronics

Orbital current phenomena and spin-orbit torque effects in transition-metal oxides and oxide-based heterostructures.

Device-oriented physics

Experimental routes toward magnetic switching, angular-momentum transfer and material platforms for low-power information technologies.
