Mathematical models describing the kinetics of biochemical reaction networks are becoming increasingly detailed. The large number of coupled nonlinear ordinary differential equations constituting these detailed models complicates analysis of their dynamics, in particular, assessment of stability and bifurcation. Model reduction aims at elimination of complexes and reactions of a detailed biochemical reaction network, thereby producing a simpler biochemical reaction network that still captures the essential dynamics and is accessible for analysis.
This project focuses on model reduction of biochemical reaction networks with bi-stable dynamics, i.e. the state-space contains two stable attractors. Bi-stability is at the origin of many phenomena in (cell) biology, such as cell differentiation. Synthetic biology produces bi-stable toggle switches that enable advanced regulatory and computational functionality. It is therefore of utmost importance that bi-stability is preserved in the model reduction process.
To address these challenges we will develop advanced model reduction methods that exploit structural properties of biochemical reaction networks with bi-stability. The novel model reduction method will be tested on a recently developed and experimentally realised DNA-based toggle switch.
Applicants should have the following qualifications:
• A PhD degree in systems and control, applied mathematics, or systems biology
• A strong interest in mathematical modelling of (bio)chemical systems and the ability to do interdisciplinary research
• Basic programming skills in Matlab
• Good command of the English language and communication skills.
