Sara Lea Sawyer is an American cell biologist who is a Professor at the University of Colorado Boulder. She investigates animal viruses that infect humans, including the emergent virus SARS-CoV-2. She was awarded the Presidential Early Career Award for Scientists and Engineers by Barack Obama in 2011.
Early life and education
Sawyer was born in Olathe, Kansas. She was an undergraduate student at the University of Kansas, where she majored in chemical engineering. As an undergraduate she worked on fuel cell technology. After graduating, Sawyer worked in the oil industry as a drilling engineer in the Gulf of Mexico.[1] She moved to Cornell University for her graduate studies, where she studied the final steps in the initiation of DNA replication.[2] Sawyer was a postdoctoral student with Harmit Malik in the Fred Hutchinson Cancer Research Center[3][4] where she investigated the protein APOBEC3G, which defends cells from HIV/AIDS by causing mutation in the virus' genetic code.[5] In response to these mutations, the HIV virus produces Vif, a protein which binds to APOBEC3G and identifies it for destruction.[5] She found that APOBEC3G evolved long before there was evidence of HIV-like viruses in primates.
Research and career
In 2011, Sawyer was awarded the Presidential Early Career Award for Scientists and Engineers.[6][7]
Sawyer co-founded the bioscience company Darwin Biosciences in 2020.[8][9] During the COVID-19 pandemic, Sawyer investigated how SARS-CoV-2 spreads between infected people. As part of this effort, she developed a fast, cheap and easy COVID-19 screening test. The test was based on a Reverse Transcription Loop-mediated Isothermal Amplification (RT-LAMP).[10] She analyzed over 72,000 COVID test samples collected from students and staff at the University of Colorado Boulder between August and November 2021. She found that only 2% of COVID patients were responsible for 90% of the circulating virus. As for students living in university of accommodation, she found that only one fifth of those testing positive in halls of residence actually infected their roommates. These infectious students carried a viral load almost seven times higher than non-spreaders. She also showed that students in single rooms were half as likely to become infected.[11]
