Graham has a 13 year background in physics, volcanology and geothermal geophysics. His experience spans a number of different areas: analogue modelling of volcanic processes; active volcano monitoring at the Montserrat volcano observatory; and most recently he has gained extensive experience utilising electromagnetic techniques to image geothermal systems. This work has been carried out in New Zealand, the Caribbean and the Western United States.
