In our work we are covering a broad range of Systems Biology topics. Some areas of special interest of mine are the following:
Network biology: Particularly focused on network reconstruction, analysis, and comprehension of complex behavior in biological systems. For example, we constructed an integrated human disease network based on nine different biological aspects, including molecular, functional, and clinical features and extracted the cancerome as a cancer-related subnetwork. Cancerome could reveal hidden mechanisms of cancer and could be useful in developing new diagnostic tests and effective new drugs.
Data integration: Working on integration of experimental data (transcriptome, metabolome, proteome, regulome, fluxome, epigenome and phenome) for reconstruction and analysis tissue-specific model. For example, to evaluate alterations in cancer cell metabolism (Warburg effect), we integrated different cancer cell’s gene expression into the human GEM. Furthermore, we analyzed reciprocal associations of metabolism and epigenetics by data integration. We also published a comprehensive review about the identification of network-based functional features through integration of gene expression into protein networks.
Method development: As a contribution to method development, I provided input to CytoKavosh (a Cytoscape plug-in which allows discovering network motifs), HomoTarget (an algorithm for prediction of microRNA targets in Homo sapiens) and CentiServer (a comprehensive centrality resource and web application for centrality measures calculation).
Metabolic modelling approaches: Using a wide range of modelling techniques, from constraint-based approaches to differential equation models, to understand the complexity of cellular metabolism.
My current projects focus on systems medicine and biotechnology projects (SYSTERACT and BESTER).
The BESTER project will develop new bioprocesses for the production of butyl esters for the bio-based chemicals market. The in situ enzymatic esterification of butyric acid (HBu) and butanol (BuOH), produced by C. acetobutylicum, to butyl butyrate (BuB) with simultaneous extraction of the ester has been successfully shown by TU Delft (NL), using a single bioreactor setup (5g/L BuB yield).
The main objective of the SYSTERACT project is through an integrated and interdisciplinary approach to develop the model actinomycete Streptomyces coelicolor into a "Superhost" for the efficient heterologous production of bioactive compounds, enabling a faster discovery of new antibiotics from environmental microbial resources (microbial strains and metagenomes). Central to this approach will be an iterative Systems Biology process, combining microbiology, genetics, biochemistry, and fermentation technology with modelling.
