- I am currently working as a senior researcher in the Department of Geospeleology and Karst Paleontology, at the "Emil Racovita" Institute of Speleology in Bucharest, Romania and I am leading the department and the U-series Geochronology Laboratory.My main research interests are:Paleoclimate reconstruction based on cave deposits:
- - spelothem dating (U-series, both TIMS and alpha spectrometry) and statistic interpretation;
- - calibration of oxygen and carbon isotopic profiles on speleothems.
- Paleogeographic reconstructions and speleogenesis based on speleothems and travertine datings;
- - reconstruction of Black Sea level changes during the last 700,000 years;
- - the evolution of the Danube Gorge during the Upper Pleistocene;
- - incision rates of some typical fluvio-karstic systems in the Carpathians.
- Paleoecological reconstruction as derived from speleothems carbon record.
I was also interested in extending the U-series method of dating to non-carbonatic spelothems, such as those formed by gypsum or hematite as well as to bone and teeth remains.In the last decade I was increasingly working on fossil deposits from caves and karst and their applications to paleoclimate and paleoenvironmental reconstructions. Of course, I was especially interested in applying radiometric dating methods, both direct and indirect in order to obtain reliable age controls on fossil accumulations and archaeologic sites such as the Pestera cu Oase, Emine Bair-Khosar, Blombos, Pestera Ursilor and others.
