Inspired by the Mugler group’s biophysics research on cell sensing and movement in fluid flow, “Upstream and Downfield” is a diptych that illustrates cell behavior alone versus together. At their finest, cells are living machines that sense mechanical and chemical stimuli that warrant them to go up or down a stream. Alone, a cell’s default instinct is to move upstream, caused by an overriding mechanical stimulus. However, in a crowded environment, the cell’s instinct fails (due to an oversaturation of chemical signals, creating a “field”), resulting in all cells moving downstream. Their movement together and separate are different; a reminder that one experience is different from a collective experience. 

Emily Xu is a studio artist and premedical student. She is a candidate for a Bachelor of Science in biochemistry with minors in chemistry and studio arts. Her artistic work comprises various mediums including painting, charcoal, clay sculpture, and mixed media. Emily’s artistic interests include surrealism and the intersection of science and art. Her work Untitled was featured in Detour: 2023 Studio Arts Exhibition at the University of Pittsburgh.
