Active tectonics of East Timor: geomorphic responses to an evolving slab rupture. Through analysis of the landscape evolution of East Timor, this project will establish new insights into basic dynamic processes responsible for formation of mountain systems. By quantifying slip rates on active faults and erosion rates across its landscape, it will provide new constraints on natural hazards for East Timor, and the broader region.

Summary
Tectonic drivers of extreme metamorphism in Eastern Indonesia. This project intends to investigate the tectonic drivers of (ultra-)high temperature metamorphism in eastern Indonesia. Subduction zones – where one of Earth's plates collapses beneath another – drive the formation of mountain belts and produce high pressure and high temperature metamorphic rocks. However, it is typically very difficult when investigating mature mountain belts to interpret how subduction was exactly involved.

Subduction zones – where one of Earth's plates collapses beneath another – drive the formation of mountain belts and produce high pressure and high temperature metamorphic rocks. However, it is typically very difficult when investigating mature mountain belts to interpret how subduction was exactly involved. Eastern Indonesia is one of the few places where active subduction can be linked directly to recent mountain building. Better understanding of how complex subduction dynamics and how mountain belts form is intended to assist natural hazard assessment in earthquake-prone areas.Read moreRead less
Building Central Asia: Linking the Growth of Asia to its Exhumation. The consumption of the Tethys Ocean and the associated collision of Gondwana-derived terranes with Eurasia resulted in the uplift of the highest mountain belt on Earth: the Himalayas. However, stresses from this collision zone propagated far into the Eurasian interior by reactivating faults and creating mountain belts along these fault zones. This project aims to map and model how and when fault (re)activation occurred by integ ....Building Central Asia: Linking the Growth of Asia to its Exhumation. The consumption of the Tethys Ocean and the associated collision of Gondwana-derived terranes with Eurasia resulted in the uplift of the highest mountain belt on Earth: the Himalayas. However, stresses from this collision zone propagated far into the Eurasian interior by reactivating faults and creating mountain belts along these fault zones. This project aims to map and model how and when fault (re)activation occurred by integrating multi-method thermochronological and structural data on major Meso-Cenozoic Central Asian fault systems. The resulting time-integrated tectonic model will aid in the understanding of the India-Eurasia collision, the building of the mountainous Central Asian landscape and its influence on the Asian climate.Read moreRead less
