My research attempts to discover new mechanisms and biomarkers for progressive organ fibrosis using the kidney as a model system. Our focus is on the identification of crosstalk between signaling cascades including TGF-beta and Growth Hormone signaling and on the role of small non-coding RNAs in this process. We are applying models of acute and chronic kidney injury to mutant and transgenic mice and rats and use cell culture systems for further analysis.
