Research Opportunity in the Earthquake Seismology Group.

The quake group is looking for an undergraduate researcher to work on ground motion prediction. The position is supported by NSF grants and targets the prediction of ground shaking for several past earthquakes in 1) southern California, and 2) the Pacific Northwest. The data is curated by current group members. The research entirely relies on time series analysis; however, the student will receive dedicated presentations on the scientific context and nature of the project. Some level coding is required...

Episodic Plate Motion and Thermal Structure in Subduction Zones Caused by Slab Folding in the Transition Zone

Abstract: Although most present-day subduction zones are in trench retreat, plate reconstructions and geological observations show that individual margins experience episodes of advancing, retreating or stationary trench motion with time-variable subduction rates. However, most laboratory and numerical simulations predict steady plate velocities and sustained trench retreat unless the slab experiences folding in the...

My research focuses on earthquake engineering and seismology. My goals are twofold: (a) close the gap between earthquake engineering and geoscience (b) apply earthquake early warning systems (EEWS) to engineering structures. I have significant experience in engineering application of EEWS, real-time seismology, and engineering application of cognitive sciences. I mainly worked on solving advanced problems of real-time EEWS and I developed the second version ElarmS which is the core algorithm of the current running EEWS in California, USA. I had been evaluating and improving earthquake early warning algorithms in California. I solved problems which real-time operations encounter such as accurate estimation of magnitude/intensity and their relation between frequency and amplitude of ground motion, and improved association/alert criteria to reduce missed and false alerts.

My research interests moreover include the engineering adaptive systems of artificial intelligence. This secondary interest with respect to cognitive modeling focuses on the application of artificial neural network (ANN) in the seismological application including pattern recognition, self-organizing maps etc. My research demonstrates how to utilize advanced supervised learning ANN techniques for EEWS applications. I wrote an ANN-based general program in MATLAB. I have gained expertise in sophisticated artificial intelligence methods to tackle the problem in this seismological and earthquake engineering environment. I applied a couple of pattern recognition algorithms such as the mixture of Gaussian, k-means, Self-Organizing Maps, decision three, compared with linear and nonlinear discriminant functions to classy quarry blast explosions and earthquakes near Istanbul. I am recently working on convolution and sequential neural network modeling using Keras tool and TensorFlow in python language.

Research Associate
Denolle Group
I am a seismologist, using seismological methods to solve geological/tectonic problems and to understand natural hazards. I am interested in a variety of research topics, including seismicity and earthquake hazards, structure and evolution of intracratonic basins and uplifts, dynamics of subduction systems, and improvements in seismic data processing methods. As a long-term interest, I aim to integrate results from multidisciplinary research fields, including geology, geophysics, geochemistry, and geodynamics in addressing tectonic questions. At Harvard University, I am conducting research on several exciting topics, mostly focusing on a better characterization of seismic wavefields and earthquake hazards for megathrust earthquakes at subduction zones, as well as earthquakes occurring along strike-slip faults.
