 1981 B.Sc., Zoology, Victoria University of Wellington, New Zealand My research interests lie in understanding the tectonic evolution of the crust and the geologic processes that form orogens (mountain belts) and shape landscapes on Earth. In essence, much of my research involves determining when, how and why orogenic belts form. I presently work in a variety of tectonic environments including extensional (West Antarctic rift system/Transantarctic Mountains, Basin and Range Province, Papua New Guinea) and convergent (Pyrenees, central Alaska Range) systems. The main tool used in my research has been low temperature thermochronology, typically apatite fission track thermochronology, but now also apatite (U-Th)/He dating. These methods are used to determine exhumation histories across orogens or in extensional terranes that allows one to determine the timing, amount and rate of exhumation and to use that information to better understand fundamental geologic processes. These studies are undertaken with the collaboration of colleagues, often other thermochronologists, structural geologists and geophysicists, and of course students.
