Cellular stress response


 

Cells live in changing environments and are frequently exposed to different types of stress. We build mathematical models of signaling pathways and networks to understand how cells respond to such stresses. Using different modeling approaches, such as agent-based or constraint-based modeling, ordinary differential equations (ODEs), and Boolean as well as stochastic modeling, we integrate a wide variety of data for cell populations and single cells. Of specific interest is the integration of different signals into a consistent picture of the cell about its state and environment and the involvement of other networks such as metabolism or cell cycle into the response of the cell to external cues.
