Research interests
My research philosophy:
In my view, mathematical modelling is an essential component of scientific investigations. Modelling involves combining intellectual creativity, physical knowledge, and mathematical techniques to understand the properties of the mechanisms underlying a physical phenomenon and make predictions.
My particular interest lies in developing dynamical models, such as nonlinear partial differential equations, and/or random field models for various physical applications. I approach these models in the context of statistical signal processing and advanced data analysis. By utilizing these techniques, I aim to gain a deeper understanding of physical phenomena and make predictions that can be tested through experimentation.
Main research expertise:
- Theoretical geophysics
- Cryoseismology
- Hydroacoustics
- Geohazards
- Random fields and processes
