BA, Harvard College

Bess Rosen is originally from Charleston, South Carolina. After receiving her bachelor’s from Harvard in 2011 she worked for two years as a technician in the Ikonomou lab at BU Med and for the following two years in Mriganka Sur’s lab at MIT. Having pulled herself away from Boston she joined the BCMB program at Weill Cornell in 2015. She is particularly interested in the regulation of pluripotency and signaling in pre-implantation human development. In her spare time she enjoys the great outdoors, singing, singing in the great outdoors, cheese, and puns about cheese.
