Going Global: Congratulations to Samantha O’Sullivan, MS ’18, on being selected as a Rhodes Scholar! As a recipient of one of the most prestigious fully funded programs in the world, Samantha will pursue a Doctorate of Philosophy (DPhil) in Condensed Matter Physics at Oxford University. As an undergraduate at Harvard, Samantha conducted research in plasma physics, nanoscale systems, and astrophysics. Outside of the lab, she advocates for social justice, through her published work on how dress codes are biased against Black girls and she founded an organization that addresses issues tied to the legacy of slavery. There is no doubt Samantha will continue using her unique multidisciplinary lens to uplift communities and advance scientific discoveries for years to come.
