Dr. Margaret Meixner and Dr. Marc Postman have been promoted by the Space Telescope Science Institute (STScI) in Baltimore, Maryland, to the position Distinguished Astronomer. Distinguished Astronomer is the highest level of appointment on the tenure track at STScI and represents a rank commensurate with the highest level of professorial appointments at major universities.
Meixner's promotion recognizes her long-term contributions to research and service at STScI. She has led international teams to study the life cycle of dust in the Magellanic Clouds using the Hubble, Spitzer, and Herschel space telescopes. Meixner joined STScI in 2002.
Postman is being recognized for his long-term contributions to the study of the formation and evolution of galaxies and clusters of galaxies. He has led important research to determine how the environments of galaxies determine their shapes and how the most massive galaxies evolve. Postman joined STScI in 1989.
