My research interest focuses on well dated recordings of paleoenvironmental changes occurring in (restricted) marine water basins during the geological past. My PhD research tackled the ‘conditio sine qua non’ of Earth Sciences: the age control. I was using an integrated stratigraphy approach (magnetostratigraphy, cyclostratigraphy, 40Ar/39Ar dating), resulting in the revised time-scale for the Paratethys domain (the ancient sea of Eurasia). I identified magnetofossil greigite uniquely produced by magnetotactic bacteria, as essential component for reliable magnetostratigraphic dating in fresh-brackish water systems. An important topic was to quantify the paleoenvironmental changes within the Dacian basin determining 87Sr/86Sr ratios as proxy for continental water input. Subsequently, I took another step by using organic geochemistry as another working tool. The d13C and dD ratios of molecular biomarkers (n-alkanes and alkenones) measured at multiple locations gave excellent results. I found out that, at the end of the Miocene, the Black Sea was subject to severe drought with extreme evaporation taking place that led to its water level draw. To summarize, I am scientifically tailored to a multidisciplinary approach. I took the chance of developing extended fieldwork experience (in Romania, Russia, Azerbaijan, Ukraine, Italy, Spain, Croatia, Serbia, etc) that, by now, is matched by equally sized laboratory practice.
