The whole is greater than the sum of its parts.
Principal Investigator

Prof. Hyunglok Kim

I am interested in hydrology, applications of Bayes’ theorem in machine learning, and global-scale water cycles. The overarching goal of my research is to provide accurate hydrological variables and solve the major challenges related to Earth system science that we will face in the coming decades. My work has practical applications for improving the quantity and quality of satellite- and model-based data to more accurately predict natural disasters and to provide a better understanding of the role played by hydrometeorological factors.
