My primary research interest resides in complex network theory and its application in earth systems and processes. At broader scale, earth systems and processes can be considered as a complex network, the main question I am trying to answer is, up to what extent these system and processes are inter and intra connected?
For my research on identification of critical nodes, I am examining the node importance in the context of different complex networks such as Ecology, Geomorphology and Hydrology. The interdisciplinary approach of my doctoral research will help in developing a better understanding of earth systems through a range of eco-geo-hydrological perspectives. My research relies heavily on multiple approaches: data analysis, statistics, long-term data synthesis, remote sensing, and geospatial analysis.
