A theoretical physicist, Wendy Zhang has studied the breakup of water droplets immersed in viscous oil, the breakup of air bubbles in syrup, and splashing water. The physics of these seemingly whimsical topics have potential biotechnological or other applications. For example, her work with experimental physicists on viscous fluids might be useful in creating microscopically small fibers, wires and particles. With collaborators at the University of Chicago, Zhang showed that air pressure makes liquids splash when they crash onto a flat surface. The American Institute of Physics named the finding one of the top physics stories of 2005. Zhang was selected as a Sloan Fellow in 2006.
