Research Interest
My research spans the interface of magmatic and volcanic processes. I investigate the chemical and petrologic characteristics of igneous rocks to unravel their history. I focus mainly on intraplate alkalic systems such as the Auckland Volcanic Field or the Dunedin Volcano, but have also studied recent eruptions at calc-alkalic arc volcanoes, at Mount Tongariro and Hunga Ha’apai (Tonga). Outlined here are some of my ongoing research projects:
