My primary research interests are the active tectonics and earthquake hazard of Iran, Central Asia and southern and eastern Africa. I use seismology, geomorphology and geodesy to study recent earthquakes, and to investigate large historical earthquakes. I am particularly interested in using these observations to understand how large-scale rheological variations affect seismic hazard and the tectonic evolution of the continents.
