    • Brief Bio

    Dr. Ott received her Ph.D. in Atmospheric and Oceanic Science from the University of Maryland, College Park, in 2006. She joined the Global Modeling and Assimilation Office at Goddard Space Flight Center in 2006, as a NASA post-doctoral fellow, and in 2011, as a civil servant. Her research focuses on understanding how small scale atmospheric processes affect atmospheric composition and our understanding of the carbon cycle.
