• Behavior of volcanoes on earth, Mars and Venus

To better understand undersea volcanic eruptions, she dove to the ocean floor in a submersible called Alvin to help develop the first-ever computer simulations of undersea eruptions, simulations that will help decipher how such eruptions help form the earth's crust and influence plate tectonics. Gregg also has reported that data on Martian volcanoes, generated by the Mars Orbiter Camera and the Mars Orbiter Laser may provide clues to questions about whether or not life has existed on the red planet. Gregg teaches courses on volcanoes, earth's history and dinosaurs. Her work is funded by National Science Foundation (NSF) and National Aeronautics and Space Administration (NASA).
