Episode Details

A 6th grade science teacher, a field trip to the Cosmosphere, lots of hard work, several advanced degrees, and a NASA internship has all been a influential part of Dr. Sarah Wallace's journey. Dr. Sarah Wallace has always been in love with space, and through her work at NASA, she's found her calling.

As a microbiologist, Sarah serves as the principal investigator for the Biomolecule Sequencer, allowing DNA to be sequenced in space on board the International Space Station. Talking to Sarah is like talking to your best friend, if your best friend happens to be a super-smart, yet down-to-Earth NASA microbiologist!

Beth and Sarah energetically enjoy discussing:

• The Kansas Cosmosphere and how it fostered the joy and inspiration for Sarah to understand space

• How we are all just walking bacteria…

• What it's like to see her experiments be flown on the International Space Station, including the first ever DNA sequencer in space!

• AND, having a space wedding. Not just a space-themed wedding, I mean, a serious space nerd let's-take-this-all-the-way SPACE wedding. Short of actually having it IN space.

Taken from adafruit.com: Dr. Sarah Wallace is currently is the NASA Microbiologist and Principal Investigator for the Genes in Space-3 Project aboard the International Space Station (ISS). She works at the NASA Johnson Space Center in Houston, Texas. Dr. Wallace conducts research to understand how the environment in space alters the behavior of microbes and runs her tests aboard the ISS. This will help us to one day identify microbes in-flight. The recent Biomolecule Sequencer (MinION) that Wallace worked on, showed that DNA sequencing in space is possible.

BONUS SHOW NOTES & QUOTES:

On being a female in microbiology: "I had a pretty even split of females and males in my graduate classes, and at my lab here at NASA, we have TONS of female scientists, and it's really exciting! I have several female colleagues that started with me right out of their undergrad or Ph. D. programs and have blossomed into become these phenomenal scientists! I feel like things are really opening up for anyone who is qualified and passionate, and it's no longer a stereotypical 'man's world'.

I got to meet with some of the women from the Apollo mission, and most of them were assistants. Now, females are running the divisions and the directorates, and females leading as subject matter experts in all disciplines. It's really great to see how big that change has been since Apollo.

Sarah attended Wichita State and loved microbiology, and molecular biology. Determined to find a graduate program that had both, Sarah found the University of Texas Medical Branch in Galveston. The NASA connection and fellowships in the life sciences through NASA allowed Sarah to conduct most of her research at the NASA Johnson Space Center for her Ph.D. dissertation.

"It's been a rewarding path, steppingstones often presented themselves to me, AND, I worked REALLY hard to make that happen. I was laser focused to get to NASA."

About Being a Part of the Team to Put the First DNA Sequencer on Station: "If you just stop and think about it, something that's very complex on Earth, sequencing DNA, has become commonplace in space! We have DNA sequencing in space! We have been sequencing DNA on board ISS since 2016. To date, we've done about 30 sequencing runs with about 6 different astronauts. Why that's important: it's been not only an incredible achievement, and there are SO many applications… from my area we monitor the station (air and water microbes) and we have no
