I am a four-field-trained paleoanthropologist with a scientific-mathematical background and a broad interest in the evolution of hominin technology and the cultural processes that govern it. I follow two independent, yet complementary, lines of research: my field work focuses on gathering new data to understand the Pleistocene human settlement of the cold and arid steppes of Central Eurasia, while my lab work tackles the question of how stone tools were used in prehistory.
