Associated Epic: Real-time geophysical data imaging while drilling
Period: 2022 – 2025

I have a keen interest in modeling geophysical data. I graduated from Idea League joint master program in Applied Geophysics, which is held at TU Delft, ETH Zurich and RWTH Aachen, and I worked on electromagnetic induction inversion in my master thesis.

In this project, I will be working on borehole electromagnetic induction tool data inversion to provide the subsurface image around the borehole during the drilling process. I am going to study on implementation of finite difference and integral equation numerical method for fast and accurate forward modeling.

For the inversion, I will explore different parameterization and algorithm that can be used for stochastic inversion to quantify uncertainty. In addition, I am going to study the effect of anisotropy in the inversion. Data-driven method such as physics-based machine learning is also considered as one possible alternative for fast computation.
