Research Interests

I am interested in studying magnetism, spin transport and spin dynamics in low dimensional condensed matter systems. We seek to exploit the interplay of charge, spin and valley degrees of freedom in quantum confined systems for developing new methods of spin flux generation, detection and control. Our current focus is to explore the spin physics in two-dimensional materials, topological systems and van der Waals based cross-dimensional synthetic hetero-structures. We employ a wide range of experimental techniques, including: atomically precise assembly of van der Waals material heterostructures, nanodevice fabrication, thin film growth, quantum spin/charge transport, spin-charge interconversion methods, magnetization dynamics, and spin pumping in mesoscopic devices.
