Curriculum Vitae:

Alexander Handwerger

My research is directed towards understanding the environmental controls on landslide motion. To better constrain the mechanisms that control landslide motion, I use satellite and airborne synthetic aperture radar interferometry (InSAR) and pixel offset tracking with SAR and optical imagery to quantify the kinematics of multiple landslides.
