Launch YoUR Career @ URSeismo

The University of Rochester seismological laboratory (URSeismo) is seeking applications from motivated PhD students to work on research opportunities in lithospheric structure and seismology. Research projects include NSF funded proposals. We use large amounts of ground vibration waveform data for earth imaging, time series waveform and spectral analysis, Bayesian inversion, etc. More details about this (and other) research projects can be found on:

Earth Imaging with Ground Vibration

In our group, we use seismological techniques to extract information about Earth’s internal physical properties (velocity structure, rheology, and composition). All these, believe it or not, can be decoded from basic recordings of ground vibrations delivered from seismometers scattered across the globe (red dots on right) that have been listening to our Earth shaking. This is the primary challenge of the seismologist – to recover as much useful information from these ground vibrations. Here are some of the thematic questions members of our group are exploring:

Research @ URSeismo

Learn about our Dynamic Planet

A great introduction to solid Earth geophysics can be gained by studying nature's fury. Interested students will learn about natural hazards, exciting geoscience research disciplines, and important concepts in plate tectonics. I will teach general introduction earth science courses as well as upper-level (under-) graduate courses starting in the Spring of 2019 (e.g., Seismology, Data Analysis and Modeling in the Earth Sciences, etc.). Watch here for current listings:

Courses @ URSeismo

Dedicated URSeismo partitions: 14 Nodes at BlueHive, CIRC (~300 Cores). Access to vista CIRC programming school. Over 200 TB of dedicated archival storage in RAID-6 for Monte-Carlo simulations.

Facilities @ URSeismo

Drs. Olugboji (PI) & Baowei Liu (Comp. Scientist) win NSF ACCESS award

Drs. Olugboji (PI) & Baowei Liu (Comp. Scientist) win NSF ACCESS award to construct new maps of Africa’s subsurface using high-performance computing and machine learning. New constraints will help understand Africa’s lithospheric structure, seismicity, tectonics, and interior dynamics.
