I use active-source seismology together with other geophysical and geological data to investigate deformation and magmatism at plate boundaries, including continental rifts and rifted margins, subduction zones, and transform boundaries.

Some current and upcoming research projects:

ALEUT - Marine seismic imaging of the Alaska subduction zone

TAMAM - Marmara Sea transform basin

SUGAR - Onshore refraction study of the South Georgia rift basin

Early-stage rifting in northern Lake Malawi (link to blog about response to 2009 Karonga earthquakes)
