| Research Abstract |
In the present project, I investigated effects of temporally inhomogeneous noise on gene regulatory systems by using statistical methods and computational simulations. In order to perform the analysis, I developed an analytical approach and applied it to several biological models such as a bistable switch and a ratchet model. The developed method can calculate many statistical properties of systems driven by the temporally inhomogeneous noise. I also studied effects of structural inhomogeneity on the performance of genetic oscillators and showed that the existence of the period mismatch in a pair of coupled oscillators enhances entrainability, i.e. the ability to respond to external periodic stimuli.
