Research

My scientific interests are in tectonics, particularly the processes that control the formation, growth, and erosion of mountain belts. I enjoy incorporating a variety of tools and approaches in my research, including field work, thermochronology, and brittle structural analysis. A major focus of my recent research has involved crystallographic fabric analysis, with a particular emphasis on the mineral quartz. Specific interests include:

  • The tectonic evolution of convergent wedges, such as the modern day Hellenic subduction wedge exposed in Crete, Greece
  • Application of sedimentary provenance tools, including detrital thermochronology, to reveal the long-term erosional history of mountain belts and patterns of sediment dispersal
  • Understanding patterns of Dauphiné twinning in quartz, with potential applications in paleostress analysis
