6-2.14 | SAVANNA DEVELOPMENT

Research interests

I focus my research on the development of African savannas in the Plio-Pleistocene. As a tool I work among other things with the analysis of stable oxygen and carbon isotopes from fossil herbivore and early hominin tooth enamel, as well as pedogenic archives to reconstruct the development of C4-grasslands as a result of changing atmospheric CO2-concentration, seasonality and distribution of precipitation, and retreat of tree cover. The southeast African savanna is here particularly interesting since the vegetation pattern can be correlated with paleontological data of the evolution and migration of the early hominids. In addition, I use clumped isotopes to detect paleotemperatures, which add valuable information to paleohabitat-reconstructions. Also, I am engaged in the method-development of simultaneous measurment of absolute concentrations of 72 elements in the periodic table  (6Li to 238U) via ICP-MS at New York University.

As a research associate at the Institute of Cognitive and Evolutionary Anthropology, University of Oxford, I am part of the Paleo-Primate-Project (PPP) in the Gorongosa National Park in Mozambique, which combines geological features of the two most fossil-rich paleoanthropological regions of Eastern and Southern Africa. The goal of PPP is to reconstruct the ecological and evolutional history of the southern part of the East African Rift from the Miocene to present.
