I am a Paleolithic archaeologist and paleoanthropologist. My research focuses on environmental change primarily in the past 2 million years and how it affected hominid biological and cultural evolution. I analyze fossil faunal remains obtained from archaeological and paleontological sites to reconstruct ancient environments through space and time and to ask questions about human evolution.
To track climate change through space and time, I use both zooarchaeological and paleontological methods. I am currently building a large comparative collection to assist me in my research. This includes comparative collection of modern species, fossil casts as well as a virtual collection based on 3D images of famous fossils.
I also use ecomorphological methods to reconstruct the environment. Ecomorphology is the relationship between the morphology of species such as diet, locomotion and size, to their environments. I am currently focused on reconstructing paleodiets of fossil animals by using 3D high power microscopes to look at the wear on the surface of teeth caused by different types of vegetation as a proxy for environmental change.
I am currently working on four main research questions:
(1) What was the ecological milieu of the Plio-Pleistocene dispersals of early Hominins from Africa and how did ecological changes affect the timing and mode of these dispersal events?
(2) What was the role of climate change in the dispersal and extinction of the Neanderthals?
(3) How did climate change contribute to the onset of sedentism and domestication in Southwestern Asia?
(4) What was the environmental milieu during the evolution of Homo in South Africa?
In addition to lab based research in my lab at TU (see Zooarchaeology Lab here), I am currently have several ongoing collaboration which include excavation in several archaeological sites in Israel, Armenia and South Africa.
