My research combines the phenotypic/clinical analysis with multi-OMICs approaches to understand the fundamental question of how over-nutritional signals alter chromatin remodelling to promote metabolic disease development.

We have so far analyzed different patient samples in the transcriptomic, cistromic and epigenomic levels and identified a group of interesting candidates involved in species-conserved and disease-relevant regulation of glucose and lipid metabolism. Of particular interest is the transcription factor coregulator GPS2, the dysregulation of which is associated with de-repressed inflammation and impaired lipid oxidation pathways, leading to type 2 diabetes and liver disease progression.

The ongoing research activity involves further investigation of the coregulator-based mechanisms in the genomic and epigenomic level in various disease contexts. Understanding such pathways is crucial for better deciphering disease mechanisms which is ultimately required for identifying novel targets with diagnostic and intervention potential.
