In this episode, Chris and Cristina talk with Anamika Nanda, a PhD student in the Department of Biological Sciences and a Women in Science and Engineering (WiSE) Fellow at the University of Southern California. Anamika’s research, conducted under the guidance of Dr. David Raichlen, examines how physical activity affects neurological health across various genotypes.
Before beginning her doctoral work, Anamika earned her Bachelor's degree in Medical Anthropology and Global Health from the University of Washington. Her award-winning honors thesis examined the relationship between motivation, physical activity, and psychosocial stress, and its impact on telomere length in collegiate swimmers and non-collegiate athletes.
We discuss her path into science, her interdisciplinary approach to understanding brain health, and how her work connects athletics, stress, and aging. Anamika’s research has been recognized with an NSF-GRFP Honorable Mention, the UW Anthropology Department’s Best Honors Thesis Award, and a Mary Gates Research Scholarship.
Tune in for an insightful conversation on the biology of movement, the value of interdisciplinary research, and what it means to study sports from a holistic perspective.

Dr. Isaura Cruz is a bioanthropologist whose research focuses on the environmental factors that contribute to human health and well-being. She has studied the development of cardiovascular and metabolic conditions among P'urhépecha indigenous Mexicans in their home communities in Michoacán, Mexico and in host communities in North Carolina, USA. Dr. Cruz uses a mixed-methods approach that incorporates nutrition, public health, and genomics while applying a biocultural lens.
The research we will discuss today is part of her doctoral dissertation, entitled International Migration and Health: P'urhépecha in the US and Mexico." Specifically, we will discuss a binational study conducted between 2018 and 2019 examining cardiometabolic health in the P'urhépecha community, an indigenous group in the state of Michoacán, Mexico. This study compares cardiometabolic health risk factors between individuals residing in their home communities in Michoacán and those residing in North Carolina. This work integrates perspectives and methods from anthropology, public health, demography, sociology, and other fields to better understand health in the context of international migration.

Chris and Courtney sit down with Dr. Haley Ragsdale to discuss intergenerational signals of matrilineal experience. Haley completed her dissertation in Anthropology at Northwestern University in 2023 under the guidance of Dr. Chris Kuzawa. She is now a postdoctoral researcher in the Anthropology Department at the University of Illinois Chicago, collaborating with Dr. Katie Starkweather on fascinating projects related to maternal and child health among the Shodagor of Bangladesh. Haley’s work is deeply rooted in evolutionary theory and the developmental origins of health and disease (DOHaD) framework, with a focus on human reproductive biology. She explores how energetic experiences shape lifetime metabolic strategies and how reproductive investments are influenced by varying environmental contexts. Currently, she’s diving into the mechanisms behind intergenerational signals of matrilineal experience and predictive adaptive responses in humans.

SoS 249: Cup, Swab, or Pad? How Collection Shapes Menstrual Biomarkers

Jake Aronoff is a human biologist studying immune function and aging from an evolutionary and ecological perspective. During his PhD, he studied how stress and social inequality impacts inflammation and immunosenescence in the Philippines and US. He is currently a postdoctoral researcher at ASU studying inflammation and aging with Ben Trumble and the Tsimane Health and Life History Project. These studies focus on the development of chronic inflammation in later life (inflammaging), the links between metabolic and immune function (immunometabolism and meta-inflammation), and the relationship between infections, inflammation, and brain aging. His research also utilizes life history theory and energetic trade-offs to understand complex changes in biological functioning in later life, like the simultaneous occurrence of inflammaging and immunosenescence.

SoS 250: Jake Aronoff's incredible journey into aging (of immune cells)

This week on the Sausage of Science, Cara sits down with two trailblazing scholars shaping the future of paleoanthropology from the African continent outward. Dr. Palesa Madupe, postdoctoral researcher at the University of Copenhagen’s Globe Institute, shares her pioneering work on enamel proteomics—reconstructing protein sequences from Paranthropus robustus and other South African hominins to unravel questions of taxonomy, sex determination, and sexual dimorphism. Joining her is Professor Becky Ackermann of the University of Cape Town, co-director of the Human Evolution Research Institute (HERI), whose influential research on evolutionary processes, phenotypic variation, and human diversity is reframing our understanding of our evolutionary story. Together, they highlight how African-led research is reshaping the global narrative of human origins, one fossil and one protein at a time.

SoS 251: Proteomics and Human Origins: Reconstructing the Past with Palesa Madupe & Becky Ackermann

Alex got her degree from the University of Notre Dame in 2022 after finishing her dissertation on the variation in brown adipose tissue thermogenesis and its effects on metabolic health markers in adults from Samoa. She is currently a postdoctoral fellow at Pennington Biomedical Research Center working on the Military Health and Nutrition Examinations Study (MHANES) (PI: Dr. Claire Berryman). In collaboration with the US Army Research Institute of Environmental Medicine, her work with MHANES examines how the interactions between environmental (i.e. temperature, altitude), behavioral (i.e. physical activity, nutrition, sleep), and physiological (i.e. body composition, energy expenditure, metabolic health markers) factors affect health and performance in active-duty service members. She frequently collaborate with colleagues on anthropological research projects focusing on the effects of physiological adaptations/adjustments to the extremes and is passionate about bringing anthropological perspectives to clinical and military-focused research.

This week on The Sausage of Science, Chris and Cara talk with Dr. Josh Brahinsky, a researcher in the Transcultural Psychiatry Department at McGill University and the Department of Religious Studies at Stanford University, whose work sits at the intersection of anthropology, psychology, and neuroscience. Josh explores how contemplative practices like prayer and meditation shape sensory experience, perception, and emotion, focusing especially on the embodied and affective dimensions of charismatic evangelical worship. With a background that bridges the humanities and sciences, a PhD in the History of Consciousness from UCSC, and a postdoctoral fellowship in Anthropology at Stanford, Josh brings a truly interdisciplinary lens to understanding what happens when people reach for the divine, and how those moments transform the body and mind alike.

SoS 253: Josh Brahinsky and The Neuroscience of the Divine

Dr. Sofía Pacheco-Fores is a bioarchaeologist whose research focuses on migration in ancient Mexico. Using a range of methods including archaeological biogeochemistry and phenotypic variation in human skeletal and dental morphology, she reconstructs migration patterns to understand the experiences of past migrants and their recipient communities. She examines the role migration played in social and cultural change, including in ancient state formation, the spread of novel material culture complexes, the expression of social inequality, and eruptions of mass violence. She has on-going collaborative research projects in central Mexico, Oaxaca, and northwestern Mexico.
In addition to her research, Dr. Pacheco-Fores is involved in science education and outreach activities with the goal of fostering increased inclusion and diversity within anthropology. She is a Senior Editor at Anthro Illustrated, a collaborative project creating illustrations of anthropologists of diverse backgrounds at work. She also encourages increased representation and participation in anthropology through the Skype A Scientist program, speaking with bilingual K-12 students about anthropology and bioarchaeology.
