Elizabeth Libby

Assistant Professor,  Bioengineering


Research Focus

Synthetic biology, microbiology, biosensor development


Elizabeth Libby joined the Bioengineering department at Northeastern in January 2021 with a research focus on synthetic biology. Previously, she was a Departmental Fellow in Systems Biology at Harvard Medical School where she led efforts in synthetic biology to develop new genetic circuits and cell-based detectors. She earned a BS in Physics from Stanford and a PhD in Physics from the University of Pennsylvania. There she transitioned to biology, imaging transcription factor binding and chromosome dynamics in bacteria. She did postdoctoral training in Microbiology at Columbia University, studying signaling systems, phenotypic noise, and antibiotic tolerance.
