Jackie Fischer is an astrophysicist, formerly in the Radio/Infrared/Optical Sensors Branch of the Remote Sensing Division and led the Infrared – Submillimeter Astrophysics & Techniques Section. She received a B.Sc. degree in physics from the Hebrew University of Jerusalem and a Ph.D. in astronomy from the State University of New York in Stony Brook. She began at NRL as a National Research Council postdoctoral associate and joined the Laboratory in 1988. She has worked on a number of infrared instrumentation projects: she was the technical manager of the HYDICE Hyperspectral Digital Collection Experiment, led the optical specification team for the ASTROCAM astrometric infrared imager for U.S. Naval Observatory, and was a member of the Infrared Space Observatory (ISO) Long Wavelength Spectrometer team. She was appointed as the Herschel Optical System Scientist and as a member of the Herschel Science Team in 2001. Her research interests are in the area of the evolution of galaxies and in particular, on the role that galaxy mergers play in the morphological transformation of galaxies, most recently concerning the structure of the nuclear regions of gas-rich galaxy mergers and in particular on the discovery of massive molecular outflows in gas-rich galaxy mergers and the implications for understanding galaxy feedback in these systems.
