Computational Systems Biology
The group's research aims to understand the function and dysfunctions of biological systems on a molecular level, taking into account the complexity arising from the interplay of biomolecules in large regulatory networks. This work is enabled by the availability of big biological datasets that are generated by high-throughput, biochemical profiling methods. Relevant data include transcriptomics, proteomics, or epigenomics, which are often assayed in combination (“multi-omics”) and at cellular resolution (“single-cell”). The computational methods we use mirror this biological complexity, spanning advanced statistics, machine learning, and network science.
