living matter is a special type of non-equilibrium condensed matter systems. We seek to build a model to understand how cells, cell colonies, and animal herds work as a team to give rise to intelligent decisions and behaviours. As an important step, we resort to molecular and particle simulations to build life on your computer. Specifically, we will apply Newton's laws to a large number of interacting, self-propelling particles and molecules, and watch how they can self organise into structures and dynamics that are forbidden in equilibrium systems. This fun research will help us understand living and active matter from a microscopic point of view, will facilitate you for your future research in biophysics, chemistry, engineering, and beyond.
