Selected Papers


Thomas Reiberger conducted seminal studies for optimizing the role of non-selective betablocker therapy in patients with cirrhosis and portal Hypertension (Reiberger, Gut, 2013; Mandorfer, Gastroenterology 2015; Reiberger, Journal of Hepatology, 2017). His HEPEX research team is focused on exploring novel treatment options for liver fibrosis and portal hypertension, such as anti-angiogenic drugs (Reiberger, Journal of Hepatology 2009), FXR agonsits (Schwabl, Journal of Hepatology, 2017) and soluble guanylate cyclase stimulators (Schwabl, Scientific Reports 2018). Thomas Reiberger is also the clinical director of the cirrhosis outpatient clinic and the Vienna Hepatic Hemodynamic Laboratory at the Division of Gastroenterology & Hepatology.

Main Research Interests:

  • Liver fibrogensis and inflammation
  • Portal hypertension
  • Rare liver diseases causing non-cirrhotic portal hypertension


Thomas Reiberger joined the LBI-RUD and CeMM in November 2018 as an adjunct PI. After obtaining his MD at the Medical University of Vienna, he did a first postdoc at the Department of Pathophysiology at MedUni Vienna, focusing on ex-situ liver perfusion and studying hepatocyte oxidative stress and biliary transporters. During his residency for internal medicine, Reiberger pursued a career as a physician-scientist while conducting translational studies on portal hypertension, liver fibrosis, and viral hepatitis. In addition to his clinical activities, he established the Vienna Hepatic Experimental Hemodynamic (HEPEX) Laboratory at MedUni Vienna. The main mission of his HEPEX research team is the exploration of novel treatment options for liver fibrosis and portal hypertension including anti-angiogenic drugs, FXR agonists, modulators of the soluble guanylate cyclase, and integrin inhibitors. In 2011, he received his venia docendi and in 2012 he obtained his board certification for internal medicine. After another postdoctoral fellowship in the United States from 2012 to 2015, Thomas Reiberger joined the faculty of the Division of Gastroenterology and Hepatology at MedUni Vienna. He conducted seminal clinical studies in the field of liver cirrhosis and portal hypertension. Thomas Reiberger is also the director of the clinical program for advanced chronic liver disease and transplant hepatology at the Vienna General Hospital. In his role as the coordinator of the Rare Liver Disease (RALID) Center of the European Reference Network (ERN) RARE-LIVER at the Vienna General Hospital, he complements the mission of the LBI-RUD with translational research on rare liver diseases.
