    Director, Iowa Low Altitude Remote Sensing Lab (I-LARS)

    My research is focused broadly on environmental monitoring. A big component of my
    research is focused on high-resolution remote sensing using Unmanned Aerial Systems
    (UAS), which includes fostering a new 3D remote sensing technique, Structure-from-
    Motion (SfM) photogrammetry. I have been working on both the technical aspects of
    SfM and pioneering its use in helping measure temporal and spatial changes in earth
    surface processes. On the applied side, my research uses a combination of remote
    sensing, GIS, and field measurements to map and monitor changes in river systems. My
    specific area of interest is monitoring river restoration projects and understanding how
    restoration affects rivers and how to evaluate the effectiveness of restoration
    treatments to better inform future restoration designs. To support my larger research
    objectives, I also to spend a fair bit of time developing and building open source
    software and hardware, which include a growing number of Python and Arduino
    projects.
