Jack Murphy came to Princeton after studying physics and philosophy at Bates College, volunteering with the Peace Corps in Southern Africa, and teaching high school for several years. Murphy's research is motivated by a fascination with the complexity and the long-term stability of Earth's climate system. Using isotope geochemistry and a range of numerical Earth system models, he studies the processes that regulate climate throughout Earth's History — in particular the silicate weathering feedback, often called “Earth's CO2-thermostat."
