Research Focus

Ruby’s research investigates the behavior of climate phenomena, especially the El Niño Southern Oscillation (ENSO), by applying complex network theory to large-scale climate data. She constructs networks from temperature reanalysis data, where geographical sites act as nodes, and their correlations form the links. Through this approach, she uncovers patterns of teleconnections that reveal underlying dynamics of ENSO and other climatic phenomena. By studying network topology, such as small-world characteristics, she has been able to forecast the onset and intensity of ENSO events with greater precision. Her work aims to create a better understanding of how climate systems are interconnected and to predict future weather patterns with improved accuracy, which has profound implications for environmental management and disaster preparedness.
