Area of Science:

  • Systems Biology
  • Computational Biology
  • Biophysics

Background:

  • Biological and biomedical tissues are complex, dynamic systems.
  • Modeling these systems faces challenges in identifying biological properties and control mechanisms, often due to missing knowledge.
  • Standard mathematical formalisms are frequently inadequate for analyzing the control structures of these dynamic biological systems.

Purpose of the Study:

  • To present a framework for building models of complex control structures in biological systems.
  • To develop methods for formulating dynamic systems in biology that enable model analysis.
  • To address the twofold problem of biological system modeling: knowledge gaps and inadequate mathematical formalisms.

Main Methods:

  • Development of a novel modeling framework tailored for complex biological systems.
