Biography

Andrea Scott is an Associate Professor in the Systems Design Engineering department at the University of Waterloo.
Her research focuses on data to improve model predictions. One of Professor Scott’s projects involve the assimilation of remote sensing data to improve knowledge of the state of sea ice in the Arctic. More specifically, she conducts research on the assimilation of sea ice thickness and/or sea ice temperatures from visual/infrared sensors, and uses Synthetic Aperture Radar (SAR) data to estimate sea ice concentration. Other projects of Professor Scott’s include the use of data assimilation to estimate parameters in turbulence models and the development of scale aware/scale adaptive parameterizations.
Before working as a professor at UWaterloo, Professor Scott was a postdoctoral researcher at Environment Canada, where she was part of a team working on the assimilation of data to improve forecasts of sea ice conditions.
