Parameter Estimation and Structure Identification

Modern molecular biology is generating data of unprecedented quantity and quality. Particularly exciting for biochemical pathway modeling and proteomics are comprehensive, time-dense profiles of metabolites and proteins that are measurable with mass spectrometry and nuclear magnetic resonance. These profiles contain a wealth of information about the structure and dynamics of the pathway or network from which the data were obtained. The retrieval of this information requires a combination of computational methods and mathematical models, which are typically represented as systems of ordinary differential equations. This long-term project thus explores different means of identifying parameters from biological time series data.
