Laboratory of Translational Metabolism Translational metabolism: Bridging the gap between research and medicine in metabolism

Our research involves applying mass spectrometry-based techniques to perform metabolomic and proteomic analysis of various biological samples. We develop and use liquid chromatography and capillary electrophoresis–mass spectrometry-based (LC–MS, CE–MS) methods for in-depth characterization and quantification of complex lipids (lipidome), polar metabolites (metabolome), various exogenous compounds such as food components and drugs (exposome), and proteins (proteome). We also focus on improving data processing, automated data curation, statistical methods, and visualization of omics data.

We have successfully integrated LC–MS methods for targeted and untargeted analysis of lipids, polar metabolites, and exposome compounds (LIMeX) for diverse sample types and used them for studies focused on cardiovascular diseases, type 2 diabetes, lipogenesis, circadian rhythms, and drug adherence.

We have also investigated the proteome of human teeth and saliva, their link to tooth decay as well as proteins to tissue architecture at clubfoot and pulmonary hypertension. Posttranslational modifications of proteins are studied in connection to aging and disease of organism.
