Nonequilibrium Statistical Mechanics

My research lies in the interface of dynamical systems, stochastic processes and nonequilibrium statistical physics. To be specific, I work on a variety of problems in nonequilibrium steady-states (NESS) of microscopic heat conduction models, including the existence and uniqueness of NESS, the rate of convergence to steady-states and the existence of local thermodynamic equilibrium.

Systematic measures of Complex Networks

As systematic measures of complex biological networks, degeneracy and complexity have been intensively used and studied in the research on system biology. By injecting external noise into networks, a quantitative study of the degeneracy and complexity can be carried out.
