After a summer of research, Eastern Michigan University Chemistry Professor Ruth Ann Armitage and undergraduate students Jaime Williams and Avi Dragun presented their findings on ancient Peruvian mummy textiles at the 11th World Congress on Mummy Studies in Cusco, Peru. This marks the first time EMU has participated in this international conference, which brings together scientists, archaeologists, and museum professionals every three years to discuss advances in mummy studies.

“Once I heard the congress would be in Peru, I knew I had to jump on the opportunity,” said Armitage. “What began as an invitation to attend quickly became a chance for Jaime and Avi to showcase their work on an international stage. When their presentations were approved, we poured our energy into preparing, knowing how meaningful this moment could be for them.”

Williams and Dragun spent much of the academic year and part of their summer analyzing yarn samples from a 2,000-year-old Peruvian mummy bundle. They used techniques such as mass spectrometry and Raman spectroscopy to study dyes, radiocarbon date fibers, and examine isotope ratios. These methods allowed them to identify plants and animals used in textile production, estimate when the textiles were made, and determine where animals like llamas and alpacas once grazed.

“Our students have been analyzing yarn samples from a single Peruvian mummy bundle, and the results have been remarkable,” said Armitage. “By studying the dyes, radiocarbon dating the fibers, and examining isotope ratios, we can determine what plants and animals were used to make the textiles, when they were created, and even where the llamas and alpacas that produced the wool once grazed. Those details help us piece together not just how the textiles were made, but also what they reveal about the culture, environment, and quality of life of the individual wrapped within them.”

Williams reflected on presenting at an international venue: “Getting to Peru wasn’t easy, but standing there with Avi and sharing the work we’ve poured so much into was unforgettable,” she said. “The experience not only validated our hard work but also strengthened my dream of becoming an analytical chemist and continuing to explore the world of archaeological chemistry.”

Dragun noted EMU’s supportive academic environment: “Being able to present our research as undergrads is rare,” she said. “The trust our professors have in us and the opportunities we’ve been given have prepared me with skills and confidence that will guide my future.”

The research was conducted through EMU’s chemistry program within its College of Arts and Sciences. The college emphasizes hands-on research experiences for undergraduates.

Eastern Michigan University was founded in 1849 as Michigan’s second oldest public university. It serves nearly 13,000 students across more than 300 programs through several colleges including Arts & Sciences; Business; Education; Engineering & Technology; Health & Human Services; as well as its graduate school (https://www.emich.edu/). National publications regularly recognize EMU for its applied education focus (https://www.emich.edu/aboutemu/rankings.php).
