Professor Paul Martin Mai’s research spans from fundamental earthquake physics toearthquake-engineering applications, examining multi-scale earthquake phenomena usingearthquake-source imaging, dynamic rupture modeling, and fault and earthquakemechanics. His work extends to strong ground-motion properties and high-performancecomputing-enabled physics-based seismic and tsunami simulations, including scattering inheterogeneous media. Another key research focus involves using seismic data to image thestructure of the Earth’s crust and upper mantle beneath the Arabian plate, with the goal tounderstand the geodynamics of the Arabian plate and Red Sea.​
