Research interests:
My research is at the intersection of data science, machine learning, and traditional physics. Specifically, I employ physics-informed deep learning and scientific AI techniques to tackle geophysics inverse problems, particularly those related to groundwater. Here are some methods I am using:
Physics-Informed Neural Networks: Combining physics-based knowledge to train neural networks with sparse data while enhancing generality and robustness.
Neural Operators: Exploring the use of neural operators as surrogate forward models to efficiently solve high-dimensional PDE and simulate physical process.
Generative Modeling: Implementing AI generative models like MoCoGAN, StyleGAN, Normalizing Flow, etc to recognize and encode content and motion of images and videos, specifically for subsurface realizations.
Bayesian Analysis and High-Performance Computing: Employing Bayesian analysis and high-performance computing to expedite numerical inverse optimization and uncertainty quantification.
Big data and Cloud Computing: Developing Spark and Hadoop softwares for multi-source data assimilation and geospatial feature engineering
