(A) computational modeling and analysis of human and animal metabolism
(B) data analysis for fluxomics (measurements of biochemical reaction rates) in tissue, biopsies and cell cultures.
Applications are human pathology (neurodegeneration, cancer, cardiac disease) and physiology (endurance sports). Approaches vary from genome-scale models of metabolism, via computational models for specific cells and organs (10-1000 biochemical reactions) to small biochemical network models which can reveal remarkable new functions for genes. Metabolic, transcriptomic and genomic data are integrated with computational models to investigate the metabolic system during disease.
Examples are: a multiscale model of metabolism, energy conversion and heat transport in the human body during a mountain time trial in the Tour de France; participation in the Recon 2 model of human metabolism; analysis of brain metabolism in Parkinson’s and Alzheimer’s disease; quantification of metabolic fluxes in vivo in cardiac biopsies using stable isotopes.

The Labeling with Isotope for a Pre-steady-state Snapshot (LIPSSS) experimental protocol for these studies was developed based on computer simulations. This method is applicable to human and animal biopsies.

Beneficial Microbes 1: 391-405, 2010. This paper describes quantification of metabolic fluxes in an in vitro model system of the bacterial community in the human gut based on stable isotope incorporation. We presented a novel analysis method of a system which was not in a metabolic steady state (i.e. metabolite concentrations are changing) by applying stable isotope methods.
We participate in the consortium for the reconstruction of human metabolism (Nature Biotechnology, May 2013) and the Virtual Physiological Human / Physiome community.
