Dr. Armstrong is a postdoc in Maitreya Dunham’s lab in the department of Genome Sciences at the University of Washington. His research focuses on using baker’s yeast (Saccharomyces cerevisiae) and modified continuous culture systems known as aging chemostats to evolve yeast cells to extend replicative lifespan. In the wild, there is little evolutionary pressure to select for cells with high replicative lifespan. Using aging chemostats provides an avenue to age billions of cells simultaneously and select for mutants with exceptionally long lifespan. He received his Ph.D. from Portland State University in 2021 where he was advised by Dr. Mark Woods.
