Curriculum Vitae

Ronit Shiri-Sverdlov studied Biology in Tel-Aviv University (Israel), where she received her PhD degree in 2002 on the basis of defining the spectrum of genetic mutations related to breast and ovarian cancer. In 2002 she moved to Maastricht University and worked as postdoctoral fellow at the department of Molecular Genetics. Shortly after her transition to Maastricht, she received a VENI NWO ZonMw fellowship that she used to in order to establish her work on non-alcoholic steatohepatitis (NASH). In addition to several other grants she received a VIDI NWO ZonMw fellowship in 2012 and subsequently became an associate professor within Maastricht University.

Ronit has full accountability for all aspects of research, staff and finances in the group, including contribution to education (group leader and PI). She ensures the efficient, timely and correct execution of all the projects. She controls activities in terms of planning, budgeting, auditing and monitoring. She is in charge of ensuring continuity in the research efforts and is responsible for monitoring the possibility of generating intellectual property. Ronit is also responsible to promote the transfer of knowledge with commercial value or societal returns into the clinic and industry. In addition to her scientific obligations, Ronit is actively involved in education in the Biomedical Sciences FHML and in the Dutch and international track for medical students as a lecturer, tutor, member of planning group and coordinator.

Nutritional factors affecting non-alcoholic steatohepatitis (NASH)

Non–alcoholic steatohepatitis (NASH) is the hepatic event of the metabolic syndrome and is characterized by steatosis (fat accumulation) and inflammation. Whereas steatosis is harmless, the inflammatory component can lead to irreversible liver damage. However, the mechanisms by which inflammation is triggered are unknown. Our aims are to identify the molecular mechanisms that trigger inflammation in NASH and related metabolic diseases, to establish innovative non-invasive markers for hepatic inflammation and to identify novel treatment options for hepatic inflammation and related diseases.

Our experiments span from basic to translational science and include both mouse and human studies.The results are expected to influence a wide area of research related to metabolic syndrome as well as fields with similar mechanisms. As such, knowledge gained in this project has enormous market potential and that substantial commercial exploitation is expected.

In Maastricht, we collaborate mainly with prof. W. Buurman, P. Lindsey PhD, J. Plat PhD and prof. A. Bast. We also have a strong collaboration with clinicians specialized in liver disease (prof. S. Olde Damink, prof. K. Dejong and G. Koek PhD). A longstanding collaboration exists with prof. M. Hofker (Groningen), prof. D. Lütjohann (Bonn, Germany), prof. E. Latz (Bonn, Germany) and C.J. Binder PhD (Vienna, Austria).
