Astrogeology Science Center

Colin Dundas is a postdoctoral Research Geologist with the USGS. He studies planetary geomorphology and surface processes using a combination of models and data from instruments like the HiRISE camera. Past and current research areas include:

  • Martian ground ice, ice-exposing impact craters, and thermokarst landforms
  • Current activity in Martian gullies
  • Large lava flows and lava-ice interaction on Mars
  • Effects of target properties and secondary craters on crater chronology
  • Floods in Martian outflow channels
