Courses

BE 567 Modeling Biological Systems

Overview

The course presents a comprehensive account of the application of modeling methodology to the investigation of biological systems. The emphasis is on an organized overview of the tools and techniques rather than the detailed mathematical structures upon which they may rely. The course draws examples widely from the current literature in an attempt to not only show the topical relevance of the subject matter but also to equip participants with an understanding of the diversity of domains to which the techniques and methodologies apply. At the center of all systems included pervails the following themes :

  • based on the science surrounding the system what mechanisms are likely to interplay
  • how can we represent those mechanisms in a model
  • how can we corroborate our understanding of the system
  • what are the implications if we are wrong...what are the implications if we are right

Course participants are given ample opportunity during the course to explore, first hand, most of the methods discussed and through team projects and seminars the opportunity to clarify their understanding of the principles and the application of the techniques.

Course Objectives
