Earth Imaging: Signals & Algorithms

Tonight, I presented my research at the Geological Society at Washington (Cosmos Club, #GSW). I was joined by the seismology group at the University of Maryland – Prof. Ved Lekic and Dr. Scott Burdick. The meeting was attended by geologists and

I attended an IRIS workshop on expanding community involvement in AfricaArray. This meeting discussed the overview of the AfricaArray and was led by Andrew Nyblade. The goal was to outline new operation and management models that will improve AfricaArray’s foundational

I attended the computational geophysics workshop at Princeton (Mar 14-15, 2016). The workshop introduced participants to SPECFEM2D, SPECFEM3D_Globe and SPECFEM3D_Cartesian [workshop link here]. These research tools are useful for full waveform modeling and inversion of the seismic wave-field. The capabilities to visualize wave-field propagation

A great start to the year! Two of my papers have successfully passed through the peer-review process. Both provide new seismological constraints on the crust underneath Pacific Ocean-islands and across the lithosphere-asthenosphere underneath normal oceanic sea- floor [posted on mantle-plumes.org].  Visit

Today, Monday, March 7, 2016 ( ~ 8 years after graduating) I made a visit to my undergraduate institution in Ife Nigeria. Even more exciting, I got a personal tour of the IFE seismic station, one of the five seismic stations on the Nigerian National

I gave a talk as part of the * IRIS Minority Recruitment Speaker Series  at Howard University on  Jan 27, 2016. The title of the talk was: Ears to the Ground: Seismic Spectrum, Applications and Careers

North Korea is the only country that has continued to test nuclear weapons. The most recent test was conducted on Jan. 6, 2016. This time, they claim its an H-bomb. It turns out that seismology can be used to validate

Today, I got to join Professor Rudnick’s class on a trip to the Smithsonian. I never expected there to be any surprises. It was billed to be a trip to see the rock and meteorite collection. In my graduate school petrology class, I

The commencement activities were really inspiring. I had dinner with my thesis advisers, reconnected with old classmates, witnessed the conferment of honorary degrees to inspiring world class intellectuals, and received my diploma, which was written entirely in Latin.   Video
