Jennifer Lippincott-Schwartz is a Senior Group Leader at Howard Hughes Medical Institute's Janelia Research Campus and a founding member of the Neuronal Cell Biology Program at Janelia.[1] Previously, she was the Chief of the Section on Organelle Biology in the Cell Biology and Metabolism Program, in the Division of Intramural Research in the Eunice Kennedy Shriver National Institute of Child Health and Human Development at the National Institutes of Health from 1993 to 2016. Lippincott-Schwartz received her PhD from Johns Hopkins University, and performed post-doctoral training with Richard Klausner at the NICHD, NIH in Bethesda, Maryland.[2]

Lippincott-Schwartz's research revealed that the organelles of eukaryotic cells are dynamic, self-organized structures that constantly regenerate themselves through intracellular vesicle traffic, rather than static structures.[2][3] She is also a pioneer in developing live cell imaging techniques to study the dynamic interactions of molecules in cells, including photobleaching and photoactivation[4] techniques which allow investigation of subcellular localization, mobility, transport routes, and turnover of important cellular proteins related to membrane trafficking and compartmentalization. Lippincott-Schwartz's lab also tests mechanistic hypotheses related to protein and organelle functions and dynamics by utilizing quantitative measurements through kinetic modeling and simulation experiments.[5] Along with Craig Blackstone, Lippincott-Schwartz utilized advanced imaging techniques to reveal a more accurate picture of how the peripheral endoplasmic reticulum is structured. Their findings may yield new insights for genetic diseases affecting proteins that help shape the endoplasmic reticulum.[6] Additionally, Lippincott-Schwartz's laboratory demonstrated that Golgi enzymes constitutively recycle back to the endoplasmic reticulum and that such recycling plays a central role in the maintenance, biogenesis, and inheritance of the Golgi apparatus in mammalian cells.[7]

Within Lippincott-Schwartz lab, current projects include several cell biological areas. For example, protein transport and cytoskeleton interaction, organelle assembly and disassembly, and cell polarity generation. There are also projects analyzing the dynamics of proteins that have been fluorescently labeled. These proteins are labeled using several live cell imaging techniques such as FRAP, FCS, and photoactivation.[8]

Lippincott-Schwartz has dedicated her most recent lab research to photoactivation localization microscopy (PALM), which allows the viewing of molecular distributions of high densities at the nano-scale.[2]
