Earth Imaging: Signals & Algorithms

Tolulope Olugboji (Principal Investigator)

Launch YoUR Career @UR

The Olugboji Earth imaging lab uses our planet’s vibrations to understand its internal anatomy and trace its dynamic history. This involves conducting planetary imaging using novel algorithms that enable Earth exploration. Our group comprises earth scientists, electrical engineers, computer and data scientists. Our research spans the entire globe and out to Mars. To discuss research interests please come up with creative ideas that overlap with current research themes before scheduling a meeting.

Projects @ URSeismo

Earth Imaging with Ground Vibration

Our research integrates innovative algorithms and large datasets, leveraging high-performance computing. We focus on: Global ocean structure, crust and mantle imaging, probabilistic deconvolution, Earth imaging with AI, Mars crustal structure, global Earth modeling with large arrays, noise monitoring, signal reconstruction, stress modeling with earthquakes, and machine learning on vast datasets. These efforts advance Earth system science, offering new insights into terrestrial and planetary structures.

Computational Geophysics Workshop @ Princeton

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

Two papers published in Gcubed

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].

A return to Nigeria and an AfricaArray station

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

Howard University: IRIS Minority Speaker

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

Life’s Rocky Start

Here is a link to the article on this really educational Nova episode on coevolution of the biosphere and geosphere. You can also watch the episode on this page below. Citation: Showstack, R. (2016), New NOVA TV show explores coevolution of rocks

Nuclear Monitoring and Seismology

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

Messengers from space: Zagamite from Mars in Nigeria

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

PhD. Commencement at Yale

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

Talk at Princenton

I gave a talk at Princeton on my research project titled The Composition of the US Continental Crust: A Transdimensional Approach It was great to interact with the entire department.
