 Dr. Joseph Resovsky

Academic and Research Interests

In science and statistics courses I give at University College Roosevelt I enjoy sharing the perspective I have gained by bringing together multiple disciplines in my research. My earth science students learn to use the mathematical physics of a hydrogen atom to describe very low notes at which the earth rings, or to use computational analogues of genetics to make five-dimensional models of the earth's interior.  They also hear about the dangers of circular reasoning that trapped modern earth scientists in the paradigm of a mantle that acted too much like a hot pot of pasta sauce and too little like a cool lava lamp.  Students in my introductory statistics and mathematics courses are shown the surprising similarities in the processes of finding the distinct components of a social construct or artistic style and of finding which parts of the core can be resolved by seismograms.

I have spent my research career pursuing creative computational solutions to seismic inverse problems, using hardware ranging from desktop workstations, to PC Beowulf clusters such as the one my students have built at UCR, to supercomputer facilities in Illinois, Minnesota, and Edinburgh. Before coming to UCR, I constructed synthetic seismograms that revealed important nonlinear effects in long-period seismograms, produced a large catalogue of hand-edited seismic data and computer aided measurements of  the very low frequency ringing of the whole earth after large earthquakes, and developed a Bayesian approach for creating deep Earth models from my data.  I am pleased to see that my catalogue, the techniques I used to construct it, and my Bayesian approach to modeling continue to be used at universities such as Cambridge and Utrecht to create new images of the mantle and core.

While at UCR I have developed research projects that enable students to make significant new contributions to the Earth Sciences.   My undergraduate collaborators have explored the global free oscillations excited by melting and sliding Antarctic ice sheet; surveyed public perceptions of the seismic risks associated with underground nuclear storage, shale gas extraction, and geothermal energy; and developed computational algorithms for simulating bell-induced shaking of church towers.   At present I am developing a seismic interferometric approach to monitoring cracks in monumental buildings, and working with fellow UCR faculty in creating new means of communicating the scientific background that shapes energy and environmental policy.
