Ruokuonuo Rose Yhome
Postdoctoral Fellow
Ruokuonuo Rose obtained her Ph.D in Archaeology from the Department of Ancient Indian History, Culture and Archaeology, Deccan College Post Graduate and Research Institute, Pune. Her research has focused on mcrowear analysis of human teeth recovered from the Jotsoma, Leshemi, Ranyek Khen, and Rikhelüwong sites in Nagaland. Her interest lies in Bioarchaeology and diet as a critical parameter for understanding human behavior and ecological adaptation, especially as determined by dental microwear analysis. She aims to address this significant lacuna by exploring the dietary behaviors of Chalcolithic (including Harappan) and Iron Age populations through analysis of dental remains recovered from Harrapan, Chalcolithic, and Megalithic sites in India during her postdoctoral fellowship from the Fulbright Foundation. She has also supervised field teams as Programme Manager at The Highland Institute, an independent research center located in Nagaland

For his doctoral thesis, he is interested, among other things, in the diet of mammals from the Pleistocene of Brazil in order to draw conclusions about the ecology of past times. He is using dental microwear analysis, stable isotopes, and radiocarbon dating for this project.

Alexandria Peterson
Doctoral Student
Alexandria graduated from Loyola University Chicago in 2014 with an honors distinction in Anthropology. She served as a TA for Human Osteology and assisted the Biological Anthropology Teaching Laboratory in other projects, including skeletal analysis for the Repatriation Department at the Field Museum. Her senior year, she was awarded the Provost Fellowship by Loyola’s Undergraduate Research Opportunities Program, and traveled to the Ungar Lab to do research for her honors thesis. Her research used metric and non- metric traits that found a set of teeth labeled Meganthropus to be Homo erectus, and compared microwear data to other populations engaged in non-dietary tooth use behaviors. Additionally, she presented her research at Loyola’s Undergraduate Research and Engagement Symposium and the Chicago Area Undergraduate Research Symposium (CAURS). Her research interests include diet and behavioral reconstruction of early hominins, particularly Homo erectus, using DMTA. She is currently a TA for the Intro to Biological Anthropology Lab.

Putu Pujiantari
Master's Student
Putu first became interested in wildlife during her childhood, while watching Steve Irwin’s documentaries. Her interest in primate behavior grew at university, particularly after reading Darwin’s Origins of Species and participating in a primate study forum. She is especially curious about the role of primates in her own culture, folkore, and religion. In fact, she conducted her undergraduate thesis research in Bali, studying the impact of anthropogenic disturbance (culture, folklore, tourism) on feeding behavior of long-tailed macaques. She hopes to continue her work on the interface between humans and primates in Bali, and is also has interested in human evolution and dental structure of non-human primates.
