Research Interests

• Experimental condensed matter physics; effects of disorder and strong electronic correlations in two-dimensional (2D) and quasi-2D systems, primarily using electrical transport and resistance noise spectroscopy techniques.
• Topics include phase transitions (metal-insulator, superconductor-insulator, structural, and Berezinskii-Kosterlitz-Thouless transitions), charge dynamics (glassy freezing and other out-of-equilibrium behavior), superconducting fluctuations, mesoscopic effects.
• Materials include semiconductor heterostructures, layered transition-metal dichalcogenides, copper-oxide high-temperature superconductors, iron pnictides, and quasicrystals.
• My research has been supported by the National Science Foundation since 1995 (see "Grants").
