Sabrina Cheng is a Research Associate II on the Proteomics and Genomics teams at the Allen Institute. Previously, she worked on the Barcoded Connectomics team, applying BARseq—a spatial transcriptomics and axonal projection mapping technique—to compare circuit organization across mouse and macaque visual cortex. Sabrina brings a non-traditional background to neuroscience, having trained in experimental physics while studying rare neutrino interactions to uncover why the universe contains more matter than antimatter. She earned her B.S. in Physics from the Massachusetts Institute of Technology and her M.S. in Physics from the University of Washington, where she developed expertise in experimental design, quantitative analysis, and instrumentation. Inspired by her earlier work probing physics beyond the Standard Model, Sabrina now applies a similar curiosity-driven, mechanistic approach to neuroscience—seeking to uncover how molecular, cellular, and circuit-level processes give rise to cognition and behavior.
