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 diagnostic technologies for SARS-CoV-2. More broadly, she is interested in combining quantitative and experimental techniques to study genetics, immunology, and infectious disease.

Brittany studied Chemical and Physical Biology and Mathematical Sciences at Harvard College, earning the Sophia Freund Prize for the highest ranking graduate(s) of 2018. As an undergraduate, she worked with Paul Clemons and Stuart Schreiber to identify genotype-phenotype associations in high-throughput therapeutic screening data. During her gap year, she used neural genomic and metabolic data to identify pathways underlying feeding behavior in Lisbon, Portugal.

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