Research interests

My research interests lie in the broad areas of computational and applied mathematics, including numerical analysis and solution of partial differential equations (PDEs), data assimilation and Bayesian inverse problems. On one hand, I focus on the development, theoretical analysis and computational implementation of numerical methods that approximate solutions of PDEs arising from complex systems in various fields, including environmental sciences, petroleum engineering, hydrology and biomechanics engineering. While PDEs serve as an essential tool to understand and predict dynamics, judicious treatment of data is crucial due to the structural complexity and computational intensity within these dynamics. In this regard, I am interested in the study of computational methods that enhance the information we can extract from existing data and knowledge by employing data assimilation and Bayesian approaches. My research aims to design rigorous and comprehensive methods for meaningful descriptions and novel treatments of systems in scientific and engineering applications, by leveraging advanced tools developed in areas including numerical analysis, data assimilation and Bayesian inference, understanding the underlying philosophies of each area, and forging connections between them.
