Mark Sorensen

I am a biological anthropologist specializing in biocultural and evolutionary approaches to human variation. My research focuses on the linkages between social and cultural processes, human biology, and health.  My research focuses on: inflammation, cardiovascular and metabolic risk; immune function and psychosocial stress;  nutrition, growth and immune function.  I am particularly interested in the biological impacts of globalization, modernization, and cultural change, in human adaptability and in ecological models for hominid evolution.

CRP Lab 3Amanda Thompson

I am a biological anthropologist specializing in human growth and nutrition.  My research focuses on understanding the biocultural and biomedical influences on growth and physiology during infancy and childhood. I am particularly interested in how early life nutrition and environmental exposures shape long-term health and obesity risk.

My research combines laboratory, anthropological and epidemiological approaches to explore the effects of early environments on growth, body composition, and reproductive development. My work focuses on: sex differences in the association between hormones, body composition, and feeding during infancy; the effects of early diet on the development of the intestinal microbiome as an underlying pathway linking infant feeding and the development of obesity; and the structural, social and maternal and infant characteristics contributing to the development of an obesogenic environment. I am currently examining the physical and social environments associated with the development of inflammation in Chinese children, adolescents, and adults through an NIH K award.

Morgan Hoke

I am a biological anthropologist specializing in biosocial and biocultural approaches to parent and infant health, nutrition, and early growth. My research focuses on the ways in which different forms of inequality get under the skin and affect our health. In particular, I am interested in the effects of uncertainty and precarity when it comes to resources and environments. I have conducted research examining infant feeding practices, illness, and early growth as well as work examining gut health and microbiome composition in a community experiencing rapid economic and nutritional transition in highland Peru. More recently, I have begun to examine the effects of housing insecurity and economic precarity on mental and physical health in the United States.

I integrate laboratory, anthropological, and epidemiological approaches in my work. In the lab, I have validated dried blood spot (DBS) based biomarkers for assessing gut health as well as utilized DBS samples to examine immune function and psychosocial stress. In the field, I deploy ethnographic methods (e.g. interviews, participant observation, and photovoice) alongside biomarker collections to provide new insights into the complex interactions between culture, society, and biology. My upcoming work in Peru, funded by the National Geographic Society, will focus on the effects of climate change on water-related health and economic and production activities as well as examine the strategies people are deploying to maintain their health and wellbeing in the face of climate change-related challenges. In addition, I enjoy science communication and sharing insights on how human biology, shaped by our unique evolutionary past, interacts with current social, political, and economic environments to influence health and wellbeing

Visiting and Affiliated Faculty

Paul Leslie

I am a biological anthropologist and pursue research on human ecology, especially population-environment interactions in East Africa as part of a series of long-term interdisciplinary projects. A principal focus of this work has been how local peoples respond — biologically, behaviorally, and demographically — to environmental change and unpredictability. Current work centers on the causes and social and ecological consequences arising from the adoption of agriculture and labor migration by semi-nomadic Maasai herding communities in northern Tanzania.  A special focus is on how households and communities respond to multiple extreme events – droughts, floods, pandemics, and more.

Charles Hilton

Chuck Hilton is a broadly-trained biological anthropologist with research expertise in the evolutionary history of Neandertals, modern human foragers, northern Kenyan pastoralists, and other small-scale indigenous human populations. He has been involved in anthropological fieldwork in Venezuela, Israel, and the American Southwest as well as analyses of pre-contact northwest coastal Inuit communities. Since 2006, he has been a collaborator with Prof. Bilinda Straight (Western Michigan University) in conducting long-term bio-cultural research projects among the Samburu, a Maa-speaking northern Kenyan pastoralist peoples who are experiencing vast cultural changes related to diet, physical activities, education, access to technology, and lethal violence as their traditional lifestyles become stressed by Westernization and climate change. Our current research is focused on examining the epigenetic effects of maternal in utero-stress seen within Samburu children conceived during the severe drought that hit East Africa in 2008-2010.

Erin Hosein

Doctoral Student, Anthropology |

I am a first-year doctoral student, and my work centers on the prevalence of food allergies in the US. Using training in nutrition, food studies, and an evolutionary perspective, I am particularly interested in how early-life feeding practices may modulate the risk of food allergies. Additionally, I explore the impact of food policy and recommendations on not only nutrition status but also how these changes affect food practices, customs, and beliefs.

I am a third-year doctoral student interested in how the birth experience and birth process affects birth outcomes. My research interests stem from my work as a labor doula in the Columbus, OH area from 2019-2020. For my doctoral research, I plan to look at how the birth experience might contribute to birth outcomes such as maternal and infant HPA axis dysregulation, maternal mental health, breastfeeding success, and maternal-infant bonding. I am also a biosocial predoctoral trainee at the Carolina Population Center, where I am working on analyzing interviews from a population of new mothers in North Carolina on their experiences with certain medical interventions during the birth process.
