In this episode of Lab Rats to Unicorns, John Flavin is joined by Dr. Kate Rubins, NASA astronaut, microbiologist, Army Major, and the first person to sequence DNA in space. With a PhD in cancer biology from Stanford and groundbreaking research on viruses like Ebola and smallpox, Dr. Rubins has spent her career at the intersection of biology, innovation, and exploration.

From her early work in infectious disease labs to running her own research facility in the Democratic Republic of Congo—and ultimately conducting over 200 experiments aboard the International Space Station—Dr. Rubins exemplifies what happens when science meets mission.

In this episode, Kate reflects on her path to becoming an astronaut (spoiler: she applied as a joke), what it’s like to conduct molecular biology experiments in microgravity, and how the constraints of space research are driving innovation in diagnostics, biotech, and health access on Earth.
