Cassandra Nickles

Dr. Cassandra Nickles is a Systems Engineer in the Applied Science Systems Engineering group at JPL working primarily for the Physical Oceanography Data Active Archive Center (PO.DAAC) project. Her work involves connecting NASA data to science and applications communities by creating and presenting coding tutorials for satellite data end-users. Dr. Nickles received her PhD in Civil Engineering from Northeastern University in May 2021 having performed research surrounding large-scale river networks and applications enabled by the Surface Water and Ocean Topography (SWOT) mission in the contexts of discharge dynamics and hydrologic model calibration. Her overarching passion is to serve society through remote sensing and hydrologic applications, facilitating data ease of access for a wide variety of users and science applications.
