About this episode

Pooja Swali discusses how ancient DNA can inform our understanding of disease spread throughout history.

How can ancient DNA help us understand how diseases spread? This month, geneticist and pathogen genomics expert Pooja Swali explains how samples of DNA from the past can reveal how diseases have spread across the world over time. We explore the what, where, how, and why of ancient DNA research, and what doors these questions have opened for the future of the field. Pooja has worked extensively on Yersinia pestis, the bacteria responsible for plague, and uncovered the existence of plague thousands of years earlier than previously anticipated.
