Event Category: ERL Events

Each year ERL invites our Founding Member companies to MIT for talks on our latest research, social events, and a business meeting.  This year’s meeting will take place 05/30-06/01/17.  If you work for one of our Founding Member companies, you should have received an invitation in April.  If you did not receive an invitation and…

Dmitry Borisov, Associate Research Scholar and Research Geophysicist at Princeton U., presents “Full-waveform inversion using body and surface waves in exploration and near-surface geophysics”. “Full-waveform inversion (FWI) is a data fitting approach to estimate properties of the Earth from seismic data by minimizing the misfit between observed and calculated seismograms. Although many attempts have been…

Dr. Tianfang Xu, Postdoctoral Research Associate at Michigan State U., presents “Bridging models and data: error-explicit Bayesian uncertainty quantification of groundwater models”. “Physically-based subsurface and integrated hydrologic models are powerful quantitative tools to support water resources decision making under varying hydrologic, climatic and anthropogenic development conditions. These models are inherently subject to errors in input…

Giovanni Ninto Occhipinti, Associate Profesor at the Institut de Physique du Globe de Paris (U. Denis Diderot) presents “No Magnitude, No Glory: The recent history of Ionospheric Seismology from Sumatra 2004 to Chile 2015 through the revolutionary observations of Tohoku-Oki 2011”. “Detection of ionospheric anomalies following the Sumatra and Tohoku earthquakes (e.g., Occhipinti et al.…

Dr. Lingsen Meng, Assistant Professor at U. California Los Angeles, presents “Improving back-projection imaging with a slowness-based aftershock calibration approach”. “Over the last decade, the development of large-scale dense seismic networks have promoted rapid progress in a broad spectrum of seismological sciences. High-frequency seismic waveforms from these large arrays have enabled back-projections (BP), an emerging…

Dr. Thorne Lay, Distinguished Professor and Director of the Center for the Study of Imaging and Dynamics of the Earth at U. California Santa Cruz, presents “Use of Seismic, Geodetic and Tsunami Data to Determine Earthquake Rupture Models”. “Determination of the space-time history of rupture during large earthquakes is valuable for understanding frictional properties of…

Chiyuan Zhang, PhD candidate in MIT’s Department of Electric Engineering and Computer Science and the Center for Brains, Minds, and Machines, presents “Automated fault detection with deep neural network”. “For hydrocarbon exploration, large volumes of data are acquired and used in physical modeling-based workflows to identify geologic features of interest such as fault networks, salt…

Dr. Sergey Voronin, Norbert Weiner Assistant Professor at Tufts U., presents “Data representation and classification”. “In this talk we will present some recent methods for efficient data representation, including sparsity preserving matrix factorizations and efficient algorithms for their construction. We will discuss some applications relevant to Geotomography. We will also discuss some data comparison and…

Dr. Anthea J. Coster, Princple Research Scientists and Assistant Director of the MIT Haystack Observatory, presents “Monitoring Space Weather with GNSS Networks: Auroras, Tsunamis, and Stratospheric Warmings”.   “In October 2015, The White House Office of Science and Technology Policy (OSTP) released a National Space Weather Strategy (Strategy) and an accompanying National Space Weather Action…

Clément Perrin, Postdocotral Research Scientist at Lamont-Doherty Earth Observatory (Columbia U.) presents “Examining the effects of faults growth and their fine-scale structures on rupture development of large earthquakes”. “Faults grow by accumulating displacement and lengthening (i.e., propagating laterally). The lengthening of faults over their long-term growth induces systematic changes of their along-strike structural maturity that…
