Andrea Loes is a Scientist III on the Write Team. She has a deep interest in developing tools and approaches to address important questions in biology. Prior to joining the Allen Institute, Andrea worked in the Bloom Lab at Fred Hutch Cancer Center, where she focused on understanding the effect of mutations in the surface proteins of influenza and SARS-CoV-2 on immune escape from human serum antibodies. While there, she developed a sequencing-based neutralization assay for influenza that results in >10-fold increase in throughput for assays critical to vaccine strain selection. She completed her PhD at the University of Oregon, where she used evolutionary approaches, as well as traditional biochemistry, to better understand exogenous and endogenous activation of Toll-like receptor 4 in vertebrates.
