Brief Bio

Dr. Sanchita Pal is a NASA post-doctoral (NPP) fellow at the Heliophysics Science Division of the Goddard Space Flight Center (GSFC). She graduated from the Center of Excellence in Space Sciences (CESSI) Indian Institute of Science Education and Research (IISER) Kolkata with a Ph.D. in 2020. Her Ph.D. thesis focused on space weather drivers and their geoeffectiveness. She has a background in Electronics and Communication Engineering with a specialization in microwave and space science. Prior to joining as an NPP fellow she was a contractor post doctoral researcher at GSFC worked in the Solar Orbiter project. Before that she was a post-doctoral fellow in the space physics group at the Department of Physics, University of Helsinki, Finland. There she worked on an ERC Consolidator Grant project dealing with unraveling the structure of solar flux ropes and their magnetosheath (SolMAG).

Her research interests include investigating the solar origin, evolution, and geoeffectiveness of heliospheric large-scale structures specifically coronal mass ejections (CMEs) that are the major driver of space weather. She has expertise in various imaging and in situ satellite data analysis techniques, empirical and data-driven semi-analytical modeling of large-scale heliospheric structures and building machine learning models to apply on satellite data.
