Charles Heywood

Biography

An exceptional earth science teacher kindled my interest in earthquakes and plate tectonics. Working as a geophysicist doing marine geology, I saw a need to maintain healthy freshwater supplies, and morphed into a geo-hydrologist. I apply geophysics for groundwater basin analysis, study aquifer mechanics and land subsidence, and model groundwater flow and transport at regional and local scales.
