Research interests

My main research focus is to elucidate mechanism controlling trophoblast determination. Proliferation, differentiation and specific maturation of human trophoblasts is a critical requirement for a proper placenta formation/function during pregnancy and failures are associated with pregnancy disorders such as preeclampsia and intrauterine growth restriction. To date, very little is known about human trophoblast progenitor cells and key factors that would determine their differentiation route along multinucleated syncytiotrophoblasts or extravillous invasive cytotrophoblasts. The identification of such factors and pathways would improve the understanding of placenta formation and might help to elucidate the etiology of placenta-associated pregnancy disorders. 

Techniques, methods & infrastructure

Primary cell culture of human trophoblasts, villous explant culture model systems and trophoblastic cell lines are used for in vitro analysis. A broad spectrum of biochemical, cell biological, and imaging techniques are used.
