Research Area: Full-waveform inversion, Migration.
About me: I am a Phd student here and I am interested in research in seismic imaging. I work to reduce the computational cost of seismic full-waveform inversion and migration without losing much quality of the image by borrowing ideas from Compress Sensing and Stochastic optimization.
