Title: Graphical description of biochemical systems via reaction networks: stability and its application

Speaker: Prof. Jinsu Kim (POSTECH)

A reaction network is a graphical configuration that can describe many biochemical systems with interactions between species (molecules). If the abundances of the species involved in a reaction network are small, then the randomness inherent in the molecular interactions is important to the system dynamics, and hence the abundances are modeled stochastically with a jump-by-jump fashion continuous-time Markov chain. In this talk, we begin with the definition of reaction networks as well as the basic modeling aspects of the stochastic processes associated with a reaction network. Then, we focus on the stability of stochastic biochemical systems using the underlying network structure. Lastly, we discuss how this stability can be used for practical problems in system biology.
