Modelling Biosystems
Full course description
The complexity of biological systems manifests itself in many features. For example, biological systems consist of a very large number of components (e.g. thousands of genes in one cell, billions of neurons in the human brain). Moreover, these components are linked by a multitude of processes, which are often nonlinear. As a consequence, we cannot make reliable predictions about these complex biosystems with intuition alone. Interestingly, mathematics naturally deals with thousands of variables and non-linearities, providing us with an excellent tool to explore complex biosystems.
The aim of this course is to provide an overview over various “mechanistic” or “white box” modeling approaches. The course will introduce the generic modeling process, important modeling concepts and terminology, and focus on equation-based modeling (and in particular ordinary and partial differential equations), agent-based modeling and constraint-based modeling. We will also touch upon the challenges of multiphysics and multiscale modeling and the inspiring avenues of in silico clinical trials and computational modeling for regulatory approval. To illustrate the various modeling approaches we cover different biological scales (intracellular, cellular/tissue and organ/patient) as well as different applications.
The course will not only provide theoretical knowledge, but will apply the various modeling approaches in hands-on practicals, thereby equipping students with Matlab skills needed in the curriculum later on. The course is thus complementary to the parallel MSB1005 Experimental Design and Data Management course which focuses on data management and analysis and introduces R. It is furthermore complementary to the preceding MSB1001 Systems Biology, in that it focuses specifically on mechanistic modeling approaches (in contrast to –omics approaches) and provides both a theoretical comprehension as well as practical training in these mechanistic approaches.
Course objectives
The general aims of this course are to give the student a thorough overview and understanding of mechanistic modelling approaches. Students will learn the theoretical concepts of equation-based models (Ordinary Differential Equations, ODEs/Partial Differential Equations, PDEs), agent-based models and constraint-based models. Students will also gain practical experience in Matlab and some other specific modelling software tools.
The intended learning outcomes of this course are:
1. Students are able to explain important concepts of mechanistic modeling in biology.
2. Students are able to describe and distinguish the scope and limitations of mechanistic modeling approaches in biology.
3. Students are able to identify and propose appropriate modeling paradigms and approaches for a given biological research problem.
4. Students are able to indicate challenges in and possible approaches to combining different mechanistic modeling paradigms to address biological problems that could not be handled through a single modeling paradigm.
5. Students are able to abstract a mathematical description in the form of ODEs or PDEs from a biological problem.
6. Students are able to apply Matlab for scientific applications.
7. Students are able to discuss the scope and limitations of important software tools for mechanistic modeling in biomedical contexts.
8. Students are able to explain important applications of mechanistic models in biomedical contexts.
9. Students are able to discuss the specific requirements of the application of mechanistic modeling approaches in clinical contexts.
