Research interests

My research seeks to understand the relationship between paleoecology, paleoenvironments and hominin evolution. My research combines a broad range of paleoanthropological methods including zooarchaeology, vertebrate taphonomy, paleontology, geology, and the use of ecologically driven actualistic studies of predator-prey interactions from archaeological perspectives. Over the last fifteen years my research has focused on the role of crocodylian predation on hominin evolution at Olduvai Gorge site, which is perhaps the most famous of all archaeological sites in the world informing on human evolution. Currently, I am co-directing a scientific drilling research program that investigates the continental core records of Olduvai Gorge to understand the paleoclimatic and paleoenvironmental contexts of hominin evolution at high-resolution. 

Research projects

Over the years I have established and collaborate in interdisciplinary research projects focusing on human evolution in Tanzania. They include;

  • Currently, I am co-directing the Olduvai Gorge Coring Project (OGCP). This project seeks to understand the role of Earth’s dynamics to hominin evolution through scientific drilling and multiproxy analyses of core record. OGCP peer reviewed special issue publications.
  • Olduvai Geochronology and Archaeology Project (OGAP)
  • Olduvai Vertebrate Paleontology Project (OVPP)
  • Olduvai Gorge Landscape Paleoanthropology Project (OLAPP).
