Principal Investigator of Juno, a New Frontiers program mission to Jupiter which began primary science in 2016. Aisha Bowe (B.S.E. & M.S.E.) worked as an intern in the Ames Research Center in 2008, before joining as an Engineer. Bowe worked in the Ames Research Center, in the Flight Trajectory Dynamics and Controls Branch of the Aviation Systems Division. Beth A. Brown (Ph.D.) was a NASA astrophysicist with a research focus on X-ray observations of elliptical galaxies and black holes. She earned a Ph.D. in Astronomy from the University of Michigan in 1998, becoming the first African-American woman to do so. Steve Chappell is an American aerospace engineer. He is a Technical Lead & Research Specialist for Wyle Integrated Science & Engineering at NASA's Johnson Space Center (JSC) in Houston, Texas Bob Dempsey (B.S.) is a NASA flight director for the International Space Station selected in 2005. As astronomer he worked at the Space Telescope Science Institute (STScI) prior to joining the ISS project. Allen F. Donovan (M.S.) worked with NASA to solve the problem of combustion instability that affected Project Mercury, and later on the pogo oscillation problems that affected Project Gemini and Project Apollo. Jeff Dozier (Ph.D.) worked as a senior member of the technical staff and the Project Scientist for a potential spectroscopy space mission at NASA's Jet Propulsion Laboratory. From 1990 to 1992 he worked at the NASA Goddard Space Flight Center as the Senior Project Scientist at the start of NASA's Earth Observing System Julian Earls was made the director of the Glenn Research Center in 2003, where he was responsible for technology, research and development, and systems development. This role involved Earls managing a budget of over a billion dollars and a work force of 4,500 Dorothy McFadden Hoover (A.B.D.) was an American physicist and mathematician. Hoover was a pioneer in the early days of NASA. She was then hired at the National Advisory Committee for Aeronautics (NACA, later NASA) in Langley in 1943 as a professional (P-1) mathematician. Usama Fayyad (Ph.D.) From 1989 to 1996 Fayyad held a leadership role at NASA's Jet Propulsion Laboratory (JPL), where his work in the analysis and exploration of Big Data in scientific applications (gathered from observatories, remote-sensing platforms and spacecraft) garnered him the top research excellence award that Caltech awards to JPL scientists – The Lew Allen Award for Excellence in Research, as well as a U.S.
