RESEARCH INTERESTS<\/span><\/span><\/p>\n

My research focuses on unraveling electronic and magnetic phenomena of solids. Among these, I have extensively investigated unconventional superconductors, low-dimensional conductors (including thermoelectric cobalt oxides, graphite, nickel pnictides), and diverse magnetic systems (quantum spin ladders, frustrated systems, single-molecule magnets, antiferromagnetic spintronics). My primary technique is nuclear magnetic resonance (NMR) that I regularly use in conjunction with extremely intense magnetic fields (up to 45 T) to discover, study and control collective electron behavior including quantum spin liquids, spin-stripe glasses, charge density waves and electron nematic phases. I am particularly interested in the interplay, and the competition, between such phases and superconductivity as well as in the effect of disorder in these systems.<\/p>\n
