Biography

Dr. Tolulope Olugboji is an assistant professor of Earth science with joint appointmens in electrical and commputer engineering and data sciences. He leads the Earth Imaging Lab. His group uses ground vibrations from seismic sensors across the globe coupled with high-performance computation, artificially intelligent algorithms, and signal processing to investigate planetary structure and dynamics. He teaches courses in nature’s fury, data analysis, Earth imaging, and signal processing. Olugboji is an associate editor of Surveys in Geophysics. His teaching and research has been recognized with an NSF Career Award.
