Underground magma triggered Earth’s worst mass extinction with greenhouse gases https://www.theguardian.com/environment/climate-consensus-97-per-cent/2017/aug/01/underground-magma-triggered-earths-worst-mass-extinction-with-greenhouse-gases.

Biggest mass extinction the world has ever seen was caused by extreme heat released during the formation of volcanic rock in Siberia 252 million years ago http://www.dailymail.co.uk/sciencetech/article-4739912/Global-climate-change-led-end-Permian-extinction.html.

Research and Teaching Interests

I am interested in interactions between tectonic and volcanic processes. Current work combines classical field geology, remote sensing, and seismic reflection methods to understand local and regional-scale deformation processes in volcano-tectonic systems. Mainly, I enjoy working at any geological setting that contains a fault, dike, fracture or volcano. Recent and ongoing studies focus on:

Development of fault systems during rift basin evolution in East Africa

The role of magma and magmatic volatiles in driving faulting, strain localization, and continental breakup

Magma emplacement in large igneous provinces

3-D architecture and magma flow within feeder systems to volcanoes
