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 recently are game-theoretic
models of strategic learning, network dynamics and their role in risk minimisation,
optimal encodings on landscapes for NP-complete problems, zero-temperature dynamics in constrained systems, and the design and analysis of experiments on perception.
Our paper on the dynamics of competitive learning (Phys. Rev. E 85, 011134 (2012)) featured in the Kaleidoscope section of Physical Review E this month!
