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.

Research @ URSeismo

Learn about our Dynamic Planet

Our courses equip students with the knowledge and skills to tackle pressing global challenges. Earth imaging and remote sensing uncover the planet's details and reveal natural hazards like severe weather, landslides, and tsunamis. Topics such as signal estimation and earthquake detection enhance early warning systems. Enroll in Nature’s Fury, Data Analysis, Earth Imaging, and Signal Processing, available for all levels.

Congrats! Evan’s Second PhD paper Published

Evan’s paper has been accepted for publication by JGR, Solid Earth. His paper addresses a fundamental question in submarine seismic imaging using high-frequency body waves. This is often referred to as “reverberation,” waves that “echo” or “sing” again and again.
