Ryoko Araki

Ryoko Araki is a PhD student in the Joint Doctoral Program between San Diego State University and the University of California, Santa Barbara. She received her Bachelor of Engineering from Kyoto University, Japan.

Ryoko's research examines the interactions among soil, water, and vegetation to better understand the resilience of global landscapes under environmental change. She works across multiple spatial scales—from catchments to global systems—using both in-situ measurements and satellite remote sensing data to identify signatures of ecohydrological processes. Her research aims to reconcile observations and theories to represent coupled water–energy–carbon systems and how they respond to climate variability and long-term change.

Ryoko is a recipient of the 2025 AGU Horton Research Grant and the 2025 Kyodai Shida Scholarship. She was also the inaugural recipient of the QUAD Fellowship, supported by the governments of the United States, Japan, India, and Australia.
