Microarray Data Analysis

The availability of time series mRNA expression data sets has spurred the race to infer Genetic Regulatory Networks (GRNs) to explain trend and causal relationships among genes measured in microarray experiments.  As a complement to such techniques Dimension Reduction Techniques, borrowing from experience on financial time series can be used to add further insight to such complex datasets. 

Novel Database Models will be developed to make use of the natural inter-relationships between data arising from microarray experiments carried out according to, for example, the MIAME standard. Finally, inferential algorithms that aim at building GRN models from these data are developed.
