Brittany Petros is a MD/PhD candidate in the Health Sciences & Technology (HST) track at Harvard Medical School. In the Sabeti lab, she has developed CRISPR-based diagnostics and has used genomic and epidemiological approaches to study SARS-CoV-2 transmission on university campuses. Broadly, she is interested in the evolution of viruses and their hosts.

Brittany studied Chemical and Physical Biology and Mathematical Sciences at Harvard College, where she earned the Sophia Freund Prize as the highest ranking undergraduate. She worked with Paul Clemons and Stuart Schreiber to study mutations that disrupt post-translational modifications in cancer. As a Fulbright Scholar in Lisbon, she studied nutrient sensing via the integration of neural genomic and metabolomic data.

Outside of the lab, you can find Brittany running along the Charles River or around the track, mentoring undergraduates, and attempting to take her cat for walks.
