Proteomics, human gut microbiome, and stress granules

My laboratory performs research in the following three areas:

1) Supramolecular structure of RNA-rich stress granules and function of stress granules in neurodegeneration. Currently, we are focused on the role of non-canonical DNA structures, G quadruplexes, in the initiation of cytoplasmic stress granule assembly.

2) Function of human gut microbiota in chronic kidney disease. We are interested in the human gut microbiome as both, a potential source of prognostic biomarkers and as a therapeutic target for the chronic kidney disease. Currently, we are investigating the effect of resistant starch supplementation on the human gut microbiome and its potential to slow the progression of chronic kidney disease.

3) Development of mass spectrometry-based proteomics tools for the analysis of protein-protein interaction networks and for metaproteomics. We have designed experimental methods and computational tools to analyze pairwise protein-protein interactions using short non-specific cross-linkers and currently are advancing these methods to large scale. In addition, we are developing metaproteomics data processing pipe-line for the analysis of microbiome-derived proteins labeled with tandem mass tags.
