My interests focus on human paleontology and behavior during the Pleistocene and at the beginning of the Holocene. Although I see human evolution through the prism of archeology, my research is grounded in a multi-disciplinary approach that integrates the results of genetics and of physical anthropology.

As a lithics specialist, I study the material culture of Pleistocene hominins to address issues related to subsistence strategies, cultural geography and population dynamics. My work on the peopling of Asia by Modern Humans, Neanderthals and the Denisovans considers late Pleistocene hominins as mobile hunter-gatherers responding to a complex and changing physical geography and environment.

​As a field archeologist, I participated in numerous Paleolithic excavations from Western Europe to the Tian-shan, including sites in western Russia, in Iran and in Uzbekistan. Since 2011, I am co-directing an international excavation project at the Paleolithic site of Tolbor 16, in northern Mongolia. In 2014, I joined an international team to conduct new research in Ningxia, north China.
