We are an experimental group studying interesting physics in fluids and complex fluids.
We care about practical phenomena in our daily life,
including:
the origin of drop splashing upon liquid-solid impact,
the drying dynamics in porous media such as soil and paint,
the coalescence of Pickering emulsion droplets, and
the freezing of water drops on a cold substrate.
Equally important are the fundamental puzzles we encounter in condensed matter physics:
Throughout crystallization how does the disordered liquid state pass through various intermediate steps and eventually reach the final solid state?
At single-particle level what is the fundamental kinetic difference between homogeneous and heterogeneous nucleation?
In disordered systems such as glass and jammed spheres, what are the distinct properties of the collective vibrational modes (i.e. phonons)?
Do active matters such as self-propelled particles or bacteria exhibit similar or totally different collective behaviors?
These interesting phenomena and questions are our current interests of research.
