Biological Systems: The course consists of (1) statistical representation for analyzing, interpreting and predicting biological data,(2) modeling description and application related to biological components involved in cellular processes, and (3) modeling trees and biological networks at molecular level. Students will learn from the point of view of quantitative modeling of biological systems: study of data related to biological systems, description and modeling of the structure and dynamics of biological components, study of interactions between the molecular systems involved in biological processes, study of genetic networks, molecular and biochemical interactions.
