Question: Einstein@Home is a volunteer distributed computing project that searches for signals from rotating neutron stars in data from the LIGO gravitational-wave detectors, from large radio telescopes, and from the Fermi Gamma-ray Space Telescope, the Einstein@Home project director is which American physicist and director of the Max Planck Institute for Gravitational Physics in Hannover Germany? 

<P0-S0> Einstein@Home is a volunteer distributed computing project that searches for signals from rotating neutron stars in data from the LIGO gravitational-wave detectors, from large radio telescopes, and from the Fermi Gamma-ray Space Telescope. <P0-S1>  Neutron stars are detected by their pulsed radio and gamma-ray emission as radio and/or gamma-ray pulsars. <P0-S2>  They also might be observable as continuous gravitational wave sources if they are rapidly rotating and non-axisymmetrically deformed. <P0-S3>  Einstein@Home examines radio telescope data from the Arecibo Observatory and has in the past analysed data from Parkes Observatory, searching for radio pulsars. <P0-S4>  The project also analyses data from the Fermi Gamma-ray Space Telescope to discover gamma-ray pulsars. <P0-S5>  The project runs on the Berkeley Open Infrastructure for Network Computing (BOINC) software platform and uses free software released under the GNU General Public License, version 2. <P0-S6>  Einstein@Home is hosted by the University of Wisconsin–Milwaukee and the Max Planck Institute for Gravitational Physics (Albert Einstein Institute, Hannover, Germany). <P0-S7>  The project is supported by the American Physical Society (APS), the US National Science Foundation (NSF), and the Max Planck Society (MPG). <P0-S8>  The Einstein@Home project director is Bruce Allen. <SEP> <P1-S0> Alessandra Buonanno is a theoretical physicist working in gravitational-wave physics and cosmology. <P1-S1>  She is a director at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) in Potsdam, Germany, leading the "Astrophysical and Cosmological Relativity" division. <P1-S2>  She holds a College Park professorship at the University of Maryland, College Park in College Park, Maryland, and is a meber of the LIGO Scientific Collaboration. <SEP> <P2-S0> Bruce Allen (born May 11, 1959) is an American physicist and director of the Max Planck Institute for Gravitational Physics in Hannover Germany and leader of the Einstein@Home project for the LIGO Scientific Collaboration. <P2-S1>  He is also a physics professor at the University of Wisconsin–Milwaukee. <SEP> <P3-S0> MilkyWay@home is a volunteer distributed computing project in astrophysics running on the Berkeley Open Infrastructure for Network Computing (BOINC) platform. <P3-S1>  Using spare computing power from over 38,000 computers run by over 27,000 active volunteers as of 2011 , the MilkyWay@home project aims to generate accurate three-dimensional dynamic models of stellar streams in the immediate vicinity of the Milky Way. <P3-S2>  With SETI@home and Einstein@home, it is the third computing project of this type that has the investigation of phenomena in interstellar space as its primary purpose. <P3-S3>  Its secondary objective is to develop and optimize algorithms for distributed computing.
