My research interests lie in sedimentology, sequence stratigraphy, and geological modelling, with a focus on reconstructing depositional environments and stratigraphic architectures. I am fascinated by how facies distribution and stratigraphic evolution influence subsurface heterogeneity. I enjoy exploring how field observations, core data, and seismic interpretation can be integrated to build meaningful models of basin-scale processes.
