I enjoy experiencing different European cultures both on holiday and through my work. In my spare
time, I enjoy playing and watching most sports, reading modern fiction, marquetry, gardening and DIY.
Research Summary
Ph.D.: 'Quantum Dynamics of Phase Coherent Structures', University of Lancaster.
Performed research in the group of Prof. C.J. Lambert working on quantum transport in hybrid normal
metal (N) - superconductor (S) mesoscopic structures. Used existing software based on a transfer
matrix technique to predict an analogue of the Aharonov-Bohm-Casher effect present in mesoscopic
rings with superconducting regions. Developed new software to compute the scattering matrix for a
given hybrid structure. Extended formulae which relate the scattering matrix coefficients to the
electrical and thermal conductance. Studied resonant transport in the presence of superconductivity, the
tunnelling conductance of a vortex core, geometrical confinement effects on the conductance of normal
wires and transport measurements in the presence of the superconducting proximity effect.
Guest Scientist, Max-Planck-Institut für Physik komplexer Systeme.
Joined the research group 'Mesoscopic Physics and Quantum Chaos' headed by Dr. K. Richter.
Continued my research in N-S systems with a paper on the dependence of the conductance on the
phase-difference of two superconductors and on superconductivity induced suppression of the
conductance in N-S systems. Studied transport in quantum wires with rough edges. Predicted
anomalous scaling with system dimensions of the correlation energy of conductance fluctuations in
such wires. Used semi-classical and numerical methods to study the density of states suppression in
integrable and rough billiards in the presence of superconductivity. Developed software to study two
interacting particles in a random potential. Used finite-size scaling to demonstrate the interactioninduced enhancement of the two-particle localisation length in one dimension. Applied these results to
the problem of electron-hole pairs in one dimension.
E.U. TMR Marie Curie Research Fellow, Universitá di Roma Tre.
Obtained a personal fellowship from the E.U. TMR programme to work with Dr. R. Raimondi.
Extended my transport software to include ferromagnetism and spin-orbit coupling. Studied the effect
of a weak exchange field on the sub-gap conductance of N-S junctions. Studied two interacting
particles in two dimensions demonstrating an interaction-induced transition from localised to extended
two-particle states. Studied the theory of electron-electron interactions in disordered metals.
Numerically iterated the renormalisation group equations for such systems to obtain accurately their
temperature and magnetic field dependence. Predicted a new probe for quantum interference effects in
such systems that gives rise to a non-linear conductivity.
EPSRC Research Associate, University of Durham.
Joined the group of Dr. C.S. Adams to study the non-linear Schrödinger model for quantum fluids.
Initial studies focused on sound emission from moving vortices and from vortex reconnections. By
studying the collision of vortex rings we could calculate the energy released as sound from vortex
reconnections. Present studies are focused upon vortex creation by moving objects and turbulence.
Work on the role of strong spin-orbit coupling in disordered conductors has been concluded.
IT Experience.
Developed software in Fortran77 and C on Unix platforms (HP-9000, SUN Sparc and Dec-Alpha
workstations, P.C.s under Linux). Limited knowledge of C++ and F90. Working knowledge of
MatLab, Mathematica and Maple.
