Unlocking the mystery of methane clathrates — on Earth and on our solar system’s icy moons

Trillions of cubic feet of natural gas are thought to lie in cold storage within Earth’s permafrost and under its oceans. That gas, however, is trapped within cage-like chemical structures called methane clathrates. Scientists are very interested in these structures, because they may have cousins hidden under the surface of the icy moons in the outer solar system.

VIDEO: Watch Bonaparte’s Terzaghi Lecture

Video screenshot of Rudy Bonaparte delivering the Karl Terzaghi Lecture on March 8, 2018. Split screen shows Bonaparte at a podium on the right and his title slide on the left, "Geotechnical Stability of Waste Fills – Lessons Learned and Continuing Challenges."

Professor of the Practice Rudy Bonaparte received the American Society of Civil Engineering Geo-Institute’s highest honor in 2018 when he was selected to deliver the Karl Terzaghi Lecture. The Geo-Institute now has posted video of Bonaparte’s presentation.

New faces: Macedo driven to understand geotechnical risks and make cities more resilient, sustainable

Assistant Professor Jorge Macedo

Though they’re relatively rare, the consequences of disasters like earthquakes, flooding and landslides are dire — and growing. Just ask Jorge Macedo, who thinks a lot about the risks to people, communities and engineering systems from those kinds of extreme events.

In the next two decades, the world faces a yawning gap in the energy we produce and the energy we consume. The School of Civil and Environmental Engineering’s Sheng Dai is working with the National Science Foundation and the U.S. Department of Energy on one of the renewable sources that could help us make up ground: geothermal energy.

Mayne to take expertise on the road as ASCE Geo-Institute Cross-USA lecturer

Professor Paul Mayne, who will be the 2018-2019 Cross-USA Lecturer for the American Society of Civil Engineers' Geo-Institute.

If he’s not in a classroom or his lab, there’s a good chance you’ll find Paul Mayne on an airplane next year.

Documenting disaster: Group led by Tech experts gathers key data after major catastrophes to prepare for the next one

Alejandro Martinez collects data in Mexico after a major earthquake in September 2017. Martinez, MSCE 2012, Ph.D. 2015, was part of a team from the Geotechnical Extreme Events Reconnaissance Association that traveled to the impact zone to gather “perishable” data about the earthquake to help scientists and engineers prepare for future events.
