Mrinal Sinha

Postdoctoral Fellow in Fibre-Based Distributed Sensing

My research primarily focuses on developing novel seismic imaging and seismic interferometry methods. I specialize in inverting for subsurface properties using gradient-based seismic inversion methods like FWI (Full Waveform Inversion) and LSM (Least-Squares Migration). I have also developed seismic imaging methods for monitoring changes in the Earth’s subsurface.

During my career as a research geophysicist in industry, I have worked on several interesting projects including the development of computationally cheaper to solve pseudo-elastic wave-equations, the incorporation of machine learning to estimate FWI starting models, and the development of data-processing workflows to mitigate elastic effects in acoustic FWI. Within the Deep Earth Imaging FSP, I am working on monitoring the Earth’s subsurface using distributed acoustic sensing (DAS) and other fibre-based measurements.
