Earth stirs life, life stirs back


My research interests started in the geologic realm and has transitioned, via paleontology, into the biological realm. My research goals are tailored toward understanding the interactions between Earth and life processes. I am interested in how geologic events force assemblage changes and organisms to evolve and how new assemblages change their environment. Diatoms present a unique opportunity to examine this cycle at digestible intervals.

My current research is part of the Hominin Sites and Paleolakes Drilling Project. The goal of which is to examine the climatological and ecological changes that influenced early human evolution in East Africa. I am using Diatom fossils to reconstruct conditions in Paleolake Hadar from 2.8 - 3.8 Million years ago in the Afar Depression of Ethiopia. The very same rock formation where the iconic Australopithecus afarensis known as ‘Lucy’ was found! I am also be studying the long term evolution of Aulacoseira in African Rift Lakes.
