My research involves utilizinging a multi-disciplinary approach to understanding explosive volcanic systems - magma petrogenesis, eruption and emplacement mechanisms of both mafic and silicic pyroclastic deposits, and the holistic interpretation of volcanic stratigraphic sequences containing effusive, explosive and reworked volcanic material.

Interests:
Reconstruction of past landscapes and environments using data gleaned from physical and geochemical studies of deposits and soils. I use these reconstructions in a variety of applications including documenting rates of dust flux during the last glacial period, understanding conditions controlling the peopling of southeast Asia by hominins, landscape-scale geoarchaeology, and restoration strategies for rivers and streams.
