Carolyn Ruppel returned to MIT to join the MIT Energy Initiative (MITEI) as deputy director in early 2025, following a decades-long career as a professor and federal research scientist. Starting in 2006, Ruppel spent nearly 19 years at the U.S. Geological Survey (USGS). When she left the USGS in 2025, she was Acting Senior Science Advisor to the USGS Chief Scientist and a ST-rank research geophysicist who had led the Department of Energy (DOE)-supported USGS Gas Hydrates Project for 15 years. In 2011, she wrote the gas hydrate supplement for MITEI’s Future of Natural Gas study.
Over several decades, Ruppel led research expeditions in the Atlantic, Pacific, and Arctic Oceans and on the Alaska North Slope and Southeastern U.S. barrier islands. She dove on the Alvin submersible, led explorations with remotely-operated vehicles, participated in ocean drilling, conducted high-resolution marine seismic programs and borehole temperature measurements through gas hydrate deposits, and co-discovered widespread seafloor methane emissions on the U.S. Atlantic margin. Her publications have focused on the dynamics of gas hydrate reservoirs, potential synergies between global warming and widespread gas hydrate breakdown, pore- to field-scale geotechnical properties of hydrate-bearing sediments, subsea permafrost degradation, and active marine acoustics and federal environmental policy.
Ruppel holds SB, SM, and PhD degrees from MIT and was a postdoctoral scholar at Woods Hole Oceanographic Institution. From 1994 to 2006, Ruppel was a geophysics professor at Georgia Tech and also served as a National Science Foundation program manager for nearly three years. In the early 2000s, she served on DOE’s Federal Advisory Committee for Methane Hydrates R&D, and she was a member of the advisory board for Centres of Excellence on gas hydrate, carbon cycle, ice dynamics and climate at University of Tromso for over a decade. Ruppel is a Fellow of the American Geophysical Union and the Geological Society of America, a past Distinguished Lecturer for the Ocean Drilling Program, and a 2024 recipient of the U.S. Department of Interior’s Distinguished Service Award, the department’s highest honor.
