Research
I am generally interested in emergent phenomena in frustrated magnets, where competing interactions between spins may stabilize unusual phases of matter, such as quantum spin liquids and nontrivial magnetic orders. Two recent themes that I have been exploring are (i) symmetry classification of quantum spin liquids and its applications to candidate materials, and (ii) magnetic field induced phases and topological magnons in Kitaev magnets. A complete list of my publications can be found in ORCID.
