    Areas of Specialisation:

    • Statistical Mechanics of Disordered and Complex Systems; i.e., statistical physics analytic, and Monte Carlo modelling and simulation, methods applied to the study of diverse disordered systems. E.g., material fracture (from crack nucleation and propagation to breakdown of materials), self-organised surface nanostructure morphology and propagation induced by ion-bombardment, molecular chirality transfer and matching (with applications to facial/object/structure recognition in databases), biophysical systems (e.g., protein folding, drug design and discovery). Same methods combined with graph theory to study the networks of diverse complex systems.

    • Quantum Theory; e.g., study and development of exact analytical or  perturbative and variational methods of solving quantum dynamical equations of motion, using linear algebraic or wave mechanics representations, and calculating the physical properties of matter; use of computational quantum chemistry softwares for the discovery of novel materials (e.g., in search of materials for cheaper, more durable and efficient solar panels for electricity generation); study of the theoretical fundamentals of the hybridised methods (perturbative, variational, density functionals, Kohn-Sham schemes, etc.) applied in the softwares relative to above interest for improvement; quantum computing problems.
