Colloids are suspensions where micrometer-sized particles (also called colloidal particles) are dispersed in. Examples include milk, blood, drug, shampoo, paint and so on. Due to brownian motions and the possiblity to apply a variety of external controls (e.g. gravity, electric field, magnetic field, laser, temperature), these colloidal particles can show a rich range of dynamics and phase behaviors. This not only allows us to study fundamentals of equilibrium and non-equilibrium statistical physics, but also to explore possible applications in material science and biophysics. Here in our group, we are mainly interested in designing experiments to study and control the behaviors of a single or a large number (up to 10^4 or larger) of colloidal particles, in simple or complex environment.
