My current research is focused on complexity in natural as well as intelligent systems. In the category of natural systems, my focus remains granular physics, with an emphasis on heterogeneities (static and dynamical), nucleation phenomena in compaction and surface dynamics. In the category of intelligent systems, I am trying to understand memory storage and preservation, with special reference to the differentiation between long- and short-term memories. Other areas in which I've worked are game-theoretic models of strategic learning, network dynamics and their role in risk minimisation, optimal encodings on landscapes for NP-complete problems and zero-temperature dynamics in constrained systems. Most recently, I've been looking at pattern formation in the fly eye, and theories of perception of language.
