My research
aims to clarify basic questions in statistical mechanics by studying simple
model systems, which are realistic enough that essential features can be
brought to light. The current focus of my studies is steady state
non-equilibrium phenomena. Computer simulations combined with analytical
methods such as renormalization group and mean field theories are my main
tools, and all of my current research projects involve interdisciplinary
studies. Current projects also involves a critique of some standard economics models
based a faulty understanding of
thermodynamics and statistical mechanics.
