Sending Yeast to the Moon With Jessica Lee

Meet the Microbiologist

Dr. Jessica Lee, scientist for the Space Biosciences Research Branch at NASA’s AIMS Research Center in Silicon Valley uses both wet-lab experimentation and computational modeling to understand what microbes really experience when they come to space with humans. She discusses space microbiology, food safety and microbial food production in space and the impacts of microgravity and extreme radiation when sending Saccharomyces cerevisiae to the moon. Ashley's Biggest Takeaways

• Lee applied for her job at NASA in 2020.
• Prior to her current position, she completed 2 postdocs and spent time researching how microbes respond to stress at a population level and understanding diversity in microbial populations.
• She has a background in microbial ecology, evolution and bioinformatics.
• Model organisms are favored for space research because they reduce risk, maximize the science return and organisms that are well understood are more easily funded.
• Unsurprisingly, most space research does not actually take place in space, because it is difficult to experiment in space.
• Which means space conditions must be replicated on Earth.
• This may be accomplished using creative experimental designs in the wet-lab, as well as using computational modeling.
