Research Interests

Contemporary condensed matter and materials physics, exploring phenomena related to superconductivity, ferroelectricity, and quantum states of matter in low dimensional electronic systems. Materials under current study include Sr2RuO4, UTe2, superconductors in low dimensions (2D, 1D, and mesoscopic), ferroelectric films (Hf1-xZrxO2) and 2D crystals (CuInP2S6), heterostructures of graphene and 2D crystals of chalcogenides, Josephson diodes, ferroelectric tunnel junctions, and other quantum devices.
