Superconductivity and nano-structured materials
Our group investigates phenomena in superconducting nanowires and thin films, as well as other condensed-matter systems, at ultra-short time scales and under extreme conditions of current density, electric field and dissipation levels. This has led to the discovery of several new regimes and effects --such as the flux-creep memory effect, hot-electron vortex instability, flux-flow “Gunn” effect, and quenched vortex motion -- and has confirmed predicted regimes such as free flux flow and ballistic supercurrent acceleration.

Psychophysics, auditory neurophysiology, and high-fidelity audio
My other interest lies at the intersection of psychophysics, human hearing, and high-end audio. Here we measure the limits of human hearing and relate them to the neurophysiology of the auditory system. These experiments also help to define the criteria for perfect fidelity in a sound-reproduction system. Our recent behavioral studies on human subjects proved that humans can discern timing alterations on a 5 microsecond time scale, indicating that that digital sampling rates used in common consumer audio (such as CD) are insufficient for fully preserving transparency.
