When Christopher Stojanowski works in his lab, he isn’t simply dealing with historic stays. To him, each tooth or fragment of bone provides a voice from the previous and a reminder that scientific information can illuminate profoundly human tales.
As the newly appointed director of Arizona State University’s Center for Bioarchaeological Research, housed inside the School of Human Evolution and Social Change, Stojanowski now leads the middle in bringing the tales of previous peoples to gentle and coaching a brand new era of students to hold that work ahead.
For 20 years, researchers within the middle have been combining biology and historical past to uncover the insights into the lives of individuals who might have left no written information by finding out their bones, tooth, pores and skin, isotopes and DNA.

A imaginative and prescient that formed a subject
The story of the middle begins with Regents Professor Jane Buikstra, whose arrival at ASU in 2005 introduced each a legacy and a daring imaginative and prescient.
Widely acknowledged because the founder of fashionable bioarchaeology, Buikstra noticed ASU as fertile floor to increase the sphere’s scope by uniting biology, archaeology and the humanities.
Upon arriving, Buikstra based the analysis middle and helped recruit Stojanowski and Kelly Knudson, each professors of bioarchaeology, to hitch Brenda Baker, who was already on school.
Together, they made ASU’s School of Human Evolution and Social Change one of the few establishments on this planet with 4 full-time bioarchaeologists — a distinction that continues to be in the present day.
“I always turn to our role in advancing knowledge of people in the past, individually and collectively,” Buikstra mentioned. “We’ve done this by training generations of ASU students to appreciate people in their historical and archaeological contexts and advancing bioarchaeological research through collaborations that draw scholars from across the globe.”
Buikstra’s method — centering scientific discovery alongside respect for individuals of the previous — has been the middle’s basis from the start.
Her present Phaleron Bioarchaeological Project in Athens continues that legacy. Excavating the stays of non-elite Athenians, her crew, which incorporates ASU college students, is revealing the lives and identities of those that helped construct the foundations of democracy however have been overlooked of its written historical past.
“These are the people upon whose backs Western democracy was literally built,” Buikstra mentioned. “Other perspectives can only enrich our understanding of this volatile, significant period.”
Buikstra’s drive to incorporate numerous views additionally guided the “21st Century Bioarchaeology: Taking stock and moving forward” workshop hosted at ASU simply earlier than the pandemic, the place 43 worldwide students gathered to evaluate the sphere’s progress. The ensuing publication within the Yearbook of Biological Anthropology has grow to be a touchstone for researchers worldwide.
A tradition of collaboration
Under Buikstra’s management, collaboration grew to become the middle’s defining trait. Faculty with distinct specialties have lengthy labored collectively in labs, co-authored papers and co-mentored college students, fostering discoveries that no single method might obtain.
“Bioarchaeology is inherently transdisciplinary, and faculty in (the center) really value collaboration,” mentioned Kelly Knudson, professor within the School of Human Evolution and Social Change. “That leads to excellent collaborative research both within the center and with folks at other institutions.”
Knudson’s OMID tuberculosis project exemplifies this. She, Buikstra and Regents Professor Anne Stone mix archaeological and genetic information from throughout South America to review how migration formed the evolution of tuberculosis.
“Bringing together researchers from different backgrounds and datasets is much more rewarding, and more fun, than staying within narrow disciplinary boundaries,” Knudson mentioned.
She additionally directs ASU’s Archaeological Chemistry Laboratory, the place college students be taught to extract data from isotopes preserved in bone and tooth enamel to disclose the place individuals lived, what they ate and the way they moved by means of altering environments.
“It’s been so fulfilling to work with students in the (lab),” she mentioned. “One of the first undergraduates who worked there is now an associate professor.”
Since its founding, the lab has skilled greater than 140 college students.
Connecting the previous and the current
For Professor Brenda Baker, her work not solely uncovers migration and well being patterns but in addition builds private connections.
“You feel like you get to know these people on some level,” she mentioned. “We have a charge to tell their stories: what happened to them, what they survived, what they went through.”
Her excavations from Egypt, Cyprus and Sudan have yielded insights that resonate far past historic historical past.
Such as “Migrations and Disruptions,” a e-book she co-edited with ASU anthropologist Takeyuki “Gaku” Tsuda, which introduced collectively archaeology, anthropology and worldwide growth to discover how people have responded to upheaval throughout time — each historic and fashionable.
“The reasons people move — climate change, conflict, survival — those are the same reasons people move today,” she mentioned.
That connection between previous and current additionally underlies Baker’s analysis on Treponemal illness, a household of infections that features syphilis. Studying historic pathogens, she says, can shed gentle on fashionable outbreaks.
“It’s very relevant today,” Baker mentioned. “We’re having a huge resurgence in syphilis around the world, including in the U.S. Understanding how the disease developed and evolved can help us track and manage it today.”
Moving between the sciences
At Gobero in Niger, Stojanowski excavated endangered cemeteries from the Sahara’s “Green Sahara Period.”
“The sequence of burials records the entire span of history from when people first moved back because the climate was better,” he mentioned. “Five thousand years later, people abandoned that part of the world because the climate had slowly been deteriorating.”
That undertaking, he mentioned, exhibits how native tales complicate the broad strokes of human historical past.
“What you’re seeing is a history that’s extremely complicated and localized and may not be the same history in another place,” he mentioned.
His later collaborations with Knudson take a deeper look at the person. Their co-edited “Bioarchaeology of Identity” texts discover how individuals’s sense of belonging, ethnicity and group will be learn not simply in artifacts, however of their our bodies.
“Bioarchaeology really sits in the middle of hard science, social science and the humanities,” he mentioned. “You can move the joystick in any of those three directions depending on what you’re interested in and what framework you’re bringing to your data.”
Looking ahead
As the middle marks its twentieth anniversary, its school stay united by a shared aim: to inform human tales that join throughout centuries and continents.
Buikstra believes that international perspective transforms each analysis and researchers.
“Conducting research abroad encourages one to become a scholar more respectful of humankind’s diversity, both today and in the past,” she mentioned. “Living in a different culture encourages this respect, along with international collaborations.”
For Stojanowski, guiding the middle into its subsequent chapter means giving a voice to the tales of the previous whereas ushering in a brand new future for the sphere.
“Our commitment to ethical research means we’re not seeking to expand the number of bioarchaeological samples, but to maximize what we can learn from existing collections,” he mentioned. “Decades of accumulated data offer immense potential, and collaboration will be key to realizing that potential in new and responsible ways.”
