Jennifer Lippincott-Swartz is Group Leader at the Howard Hughes Medical Institute Janelia Research Campus. Her lab uses live cell imaging approaches to analyze the spatio-temporal behaviour and dynamic interactions of molecules in cells with a special focus on neurobiology. Before Janelia, Lippincott-Swartz was a primary investigator and chief of the Section on Organelle Biology in the Cell Biology and Metabolism Branch. Her work there included a collaboration with physicists Eric Betzig and Harald Hess (now group leaders at Janelia), who proposed a new function for the photoactivatable protein. The scientists used the protein to generate photoactivatable fluorophores, or dyes, which enabled them to illuminate different sets of molecules sequentially, creating a microscope image far more detailed than previously possible. The method, called super-resolution microscopy, garnered Betzig the 2014 Nobel Prize in Chemistry.
