  The research in biophysics group focuses on the dynamical and statistical properties of molecular and cellular biological systems, including the measurement uncertainty of biological receptors, the stability of biochemical networks under extrinsic noises, the entropic force and stochastic thermodynamics of proteins and biological polymers, the efficiency of free energy transduction into mechanical work in biological motors, and the bifurcations on the neural signal under ion channel defect.
