  • Brief Bio

    Dr. Craig Markwardt has been a research scientist at NASA Goddard Space Flight Center since 1997. He first worked with Jean Swank of the RXTE PCA project, on the studies of X-ray binaries. He has studied millisecond X-ray pulsars, accreting black hole microquasars, and has performed long term monitoring of the galactic center with the PCA instrument. Since 2001, he as also worked on the development and flight of the BAT instrument aboard the Swift gamma-ray burst mission. In addition to developing ground software for burst work, Markwardt has been using BAT survey data, both to continue X-ray binary work, and to search for faint active galactic nuclei.  In 2009, Markwardt joined the GEMS project team and is excited to open a new frontier in the systematic study of X-ray polarimetry.  Markwardt will manage the science operations effort including science software, data processing and observational planning.
