Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

Ghosh is an earthquake seismologist and an associate professor at the University of California, Riverside. He received his Ph.D. in geophysics from the University of Washington, Seattle in 2011. He is interested in understanding the physics of earthquake slip and rupture dynamics by studying a wide spectrum of earthquake signals, including signals associated with slow earthquakes. He specialized in seismic array techniques and its applications in imaging earthquakes — big and small, slow and fast. Ghosh is also interested in aftershock studies, and how fault structure influences earthquake rupture.
