Research Interests
My primary research involves the use of satellite geodetic data (Global navigation satellite system (GNSS) and synthetic aperture radar) to understand and predict coastal hazards. I specialize in large-scale deformation mapping using Interferometric synthetic aperture radar (InSAR).
​
Other research interest include: Biogeophysics and near surface geophysics.
