Biographical Overview
Brad Hager earned his Ph.D. from Harvard University in 1978 and then became a professor at Caltech’s Seismological Laboratory. He joined MIT in 1989 where he is now the Cecil and Ida Green Professor of Earth Sciences in the Department of Earth, Atmospheric and Planetary Sciences (EAPS). Brad became the Director of ERL in June, 2012. Brad’s research interests include the relationship between space-geodetic observations of surface deformation, earthquakes, and dynamical processes in the Earth’s interior. He has expertise on tectonic earthquakes in regional fault systems, as well as deformation and earthquakes induced by reservoir production. Hager is on NASA’s NISAR Science Definition Team, providing input on earthquake, hydrocarbon, carbon sequestration, and hydrologic applications. He is also a Fellow of the American Geophysical Union and the American Academy of Arts and Sciences. He has been awarded the Macelwane and Lehmann Medals by the American Geophysical Union, the Woollard Award by the Geological Society of America, and the Augustus Love Medal by the European Geophysical Union.
