Braden is a geophysicist who works on volcanic and alpine hazards for risk management and warning purposes all around the world. His specialty and interests lie in using numourous geophysical techniques to determine the location of hazard sources in real-time, understand the physical properties and dynamics of such hazards, and to develop risk management solutions for pre-event guidelines, during event warnings, and post-event calibrations.
