RESEARCH INTERESTS
I am interested in how we communicate evolution to students and to the general public in a range of media, from the classroom to the newsroom. Additionally, I remain engaged with and interested in the subject of my master's thesis - the taphonomy of early hominins and the ecological dynamics that existed between large carnivores and those small-bodied ancestors during the Pliocene and early Pleistocene, from about 4 to 1 million years ago.

CURRENT PROJECTS
My dissertation is a cultural examination of the ways in which evolution is communicated textually and visually in formal and informal education media (e.g., biology textbooks, classrooms, and popular science magazines and television), and how that contrasts with the language and level of esoteric detail used in peer-reviewed literature. One goal is to better understand the transition of knowledge from the language of scientists to the more accessible language of educators and science writers. Additionally, I will be looking at the intersection of the "evolution-creation debate" over the past several decades and what impact it has had on evolution and general science education over time.

RESEARCH INTERESTS
My current research interests focus on Human Ecology and Animal Adaptive Behavior.

CURRENT PROJECTS
My current Ph.D. research thesis focuses on the human-baboon interface coexistence in human modified habitats by examining different anthropogenic land use practices and their influence on baboon socioecology and human-wildlife interactions. My findings will contribute to the practicalities of solving issues for the continued coexistence between humans, baboons and other species. First, examining the olive baboon's response to particular types of environmental changes will provide insights on how this species adapts to changes that are likely to occur in habitats where baboons and human coexist. Secondly, understanding how local people view and interact with baboons and other wildlife provides a means of evaluating whether local communities can be encouraged to make land use decisions aimed at facilitating the human-wildlife coexistence.

My future research interest will be directed towards evaluating land use, arising from shifting tenure systems, have stimulated the development of alternative ecological practices of humans attempting to adapt to dynamic and challenging conditions. This approach will also entail examining how various human-modified ecologies evoke economic, and political issues in different social groups as a reflection of their varying cultural ideologies. In particular, I focus on the role of a set of land use practices - such as ecotourism and community conservation based projects - in evaluating how space, resources (nature) are valued and utilized by different groups of humans. These practices extend to global trends that treat nature - particularly wildlife - as commodities whose function or purpose is to sustain local lifestyles. Of particular interest, I would like to evaluate the interplay between the "old" (local, ethnic) and "new" (Western) ideologies as a way to understand how they are integrated within a regional context and how this synthesis generates into local norms and ecological practices for better management and conservation goals.

RESEARCH INTERESTS
Fossil preparation, Miocene apes, the functional anatomy of the pelvis, and reconstructing primate locomotion in the fossil record. My field experience includes work at two sites in Spain (a Neandertal cave site in Murcia and a Roman necropolis on Menorca), as well as at the Miocene locality of Rudabanya, Hungary.

CURRENT PROJECTS
My dissertation focuses on using the internal trabecular anatomy of the pelvis in conjunction with its external morphology to reconstruct locomotion in extinct primates, particularly Miocene apes and australopithecines. I am interested in testing locomotor hypotheses via high-resolution X-ray computed tomography (HRXCT) and contributing to ongoing debates in paleoanthropology about the evolutionary context of the rise of bipedalism in hominins. I am also involved in Dr. Robert Scott’s project on the influence of food material properties and cooking on meat-eating performance in human subjects.

Research Interests:

My research goals concern the quantitative reconstruction of differential stone tool production behaviors among Oldowan hominins. To accomplish these goals, I have developed a new method of analysis called Behavioral Lithic Analysis (BLA). BLA uses replicated stone tool assemblages to identify morphological markers that accurately identify stone tools produced using known behaviors. These known behaviors are then used as a baseline model to compare archaeological material of unknown behavioral origin. My dissertation work compares the production behaviors of Koobi Fora, Northern Kenya Oldowan-producing hominins to those production behaviors utilized at Olduvai Gorge, Tanzania. The replication experiments outlined in BLA methodology must occur using the same raw materials utilized by the stone tool producers who created the archaeological assemblage in question. I am therefore replicating Oldowan assemblages using raw materials native to the Lake Turkana Basin and to Olduvai Gorge.

Broadly, BLA will provide a means of answering a broad array of questions concerning both the Oldowan and other stone tool industries:

• How do Oldowan production behaviors vary on an inter- and intra-regional scale?
• What selective pressures led to differences and/or similarities in stone tool production behaviors?
• How does site usage vary in terms of technology both within and between archaeological regions?
• What does technological variation mean in terms of stone tool function, ranging behaviors, and cultural maintenance?
• How do the fracture mechanics of different raw materials affect how they were utilized for stone tool manufacture?
• Can we determine raw material preference based on how stone tools were produced?

The importance of determining production behaviors associated with both individual flakes and entire archaeological assemblages is the comparative value of this information. When the specific methods of production are understood, production methods between sites, both temporally and geographically, become directly comparable. This means that technological behaviors can be compared between sites to determine relationships of technology through time (the evolution of stone tool technology) and how technology was utilized to cope with changing environmental conditions. My research attempts to build a bridge between analytical techniques so that researchers studying vastly different sites can begin asking new questions and addressing these questions in novel, comparative, and collaborative ways.

Research Projects:

• Koobi Fora-Olduvai Gorge Comparative Lithics Project: Despite the long history of archaeological analysis at the renowned East African sites of Koobi Fora and Olduvai Gorge, no direct, quantitative comparison of lithic assemblages has ever been undertaken. My Comparative Lithics Project seeks to quantify and identify the individual production behaviors utilized to create the Oldowan stone tools in each respective region. Since the early descriptions of Oldowan lithic implements by L.S.B. and Mary Leakey, the Oldowan has been largely considered a uniform technology; it has been described as simple, expedient, and primitive. However, as more evidence comes to the surface, it appears that Oldowan hominins demonstrated preferences for particular raw materials, forethought in how they procured those raw materials, and a complex understanding of stone fracture mechanics. But did hominins in different regions produce stone tools in the same ways? If so, how was this similarity maintained? If not, what selective pressures or cultural norms led to this difference? The development of the methodology that allows for these conclusions to be reached also provides a way for researchers to directly compare technological production behaviors between a broad array of sites.

• Experimental Acheulean Studies: The Acheulean remains a famous, yet poorly understood, technology. Though thousands upon thousands of Acheulean bifaces have been recovered, the production behaviors associated with these artifacts remains elusive. Many theories have been put forward regarding the purpose, function, and symmetrical maintenance of the hand-axe, but none have quieted the debate of what the true purpose for hand-axe production was. The Experimental Acheulean Project uses a middle range approach to the Acheulean by replicating bifaces beginning with the initial stage of production. Spalling experiments examining what variables determine successful flake removal, including hammer size, boulder size and shape, and force used will provide useful insights into the unique production behavior associated with the Acheulean: large flake production.

• Raw Material Fracture Analysis: Oldowan hominins had a clear understanding of how rock differentially fractured and utilized this knowledge to create large assemblages of stone tools. Did these hominins utilize different behaviors with different raw materials due to differences in the way each raw material fractured? Current research is examining the consistency with which materials from Olduvai Gorge, Tanzania and Koobi Fora, Kenya fracture. Combined with results from the Comparative Lithics Project, understanding differential fracture mechanics will allow for more definitive conclusions of how hominins utilized their surrounding resources and how hominin populations differed from one another in terms of their technological behaviors.
