Colin Dundas is Postdoctoral Research Associate and holds his Ph.D. in Planetary Sciences from the University of Arizona. His research interests include: planetary geomorphology and surface processes, particularly focusing on the surface of Mars. I use a combination of image analysis (largely using data from the HiRISE camera) and modeling to examine the formation and evolution of surface features. This helps to understand the processes and conditions which have shaped the present surface. I am particularly interested in periglacial and volcanic features and the nature of Martian ground ice.
