Brief Bio

Dr. Pan joined Goddard Earth Sciences Data and Information Services Center (GES DISC) at NASA GSFC in 2020 as a senior scientific software developer, working on data services including curating NASA's earth data (e.g., MERRA-2 and hydrology data such as GLDAS, NLDAS, and FLDAS) and developing software. She also actively writes scientific articles and data recipes, and interacts with data user communities. She had worked on understanding the interaction of air pollution with climate using models and satellite observations in the NASA GSFC Atmospheric Chemistry and Dynamics Laboratory as a research scientist during 2009-2020, and as a NASA NPP postdoc fellow during 2013-2015. Dr. Pan received her Ph.D. majoring in Climate Dynamics in 2009 from George Mason University.
