networks, mountain objects, folds, dunes, landscapes, and rock porous media. He developed specific technologies and spatial algorithms for using data acquired at multiple spatial and temporal scales for developing cogent domain-specific models. His work employs concepts stemmed out of recent theories—such as mathematical morphology, fractals, chaos, and morphometrics—to develop spatial algorithms for (i) pattern retrieval, (ii) pattern analysis, (iii) simulation and modeling, and (iv) reasoning and visualization of the spatial and temporal phenomena of terrestrial and GISci relevance. His studies show that there exist several open challenges that need to be addressed by mathematical geosciences community. One of such challenges is to understand the complexity in spatiotemporal behaviors of several terrestrial phenomena and processes via construction of process-specific
