Architecture and regulation of metabolic networks
Reporter algorithm integrates omics data with metabolic network and thereby identifies metabolic regulatory hotspots. M1 - metabolite; G1-5 - upregulated genes; purple/ green/blue circles & squares - transcription factors and corresponding binding motifs.
Mathematical and statistical tools provide essential theoretical basis to our quest to uncover basic principles underlying operation of cellular metabolic networks. To this end, we are developing new model formulations and algorithms that are motivated by the underlying biological questions (for more information, see our EMBLgroup page.
Holistic understanding of the functioning and regulation of complex metabolic networks requires identifying biologically meaningful operating points in a high-dimensional space. We use linear and mixed-integer linear programming (MILP) tools to tackle the resulting modeling challenges. We have developed several in silico models for quantitatively predicting metabolic phenotypes from a defined genotype. To enhance the predictive power of metabolic models, we are also developing methods to integrate genomic, transcriptomic, proteomic and metabolomic information.
