My research interests are in planetary geology, sedimentology, early Earth processes and geoscience education. My current research focuses on studies of Precambrian meteor impacts and the implications for the early Earth. I also look at modification of the Martian surface through fluvial and diagenetic processes. In addition, I collaborate with cognitive scientists on understanding spatial reasoning in the geosciences as part of the NSF Science of Learning Center: Spatial Intelligence and Learning Center.
I teach upper level/graduate classes in Sedimentary Petrology (Adv Sed Pet syllabus) and Planetary Geology (Planetary_syllabus 2014), and teach an undergraduate general education class, “Evolution and Extinctions” (Evolution and Extinctions syllabus Fall 2014).
