Sumiko Kubo is a Professor at the School of Education, Waseda University, where she has served since 2006 (previously as Associate Professor from 2001-2005). Her academic career began at Chuo-gakuin University (1995-2000) as Lecturer and Associate Professor. She holds a Doctor of Science from Tokyo Metropolitan University and maintains an active research profile in physical geography and geomorphology with international collaborations across Asia. Professor Kubo's research focuses on the intersection of physical geography, geomorphology, and Quaternary science, with particular emphasis on river systems, delta formations, and their relationship to human settlements. Her work spans Japan (Kanto Plain, Tokyo area), Cambodia (Mekong River basin), Vietnam (central region), and India (Krishna and Godavari Deltas). She employs multidisciplinary approaches combining field surveys, sediment analysis, remote sensing, and historical records to understand landscape evolution across geological and historical time scales. Her recent publications demonstrate consistent focus on deltaic systems and river geomorphology, with increasing attention to human-environment interactions and contemporary issues like flood hazard mapping. A notable trend is her examination of how ancient civilizations adapted to dynamic river environments in Southeast Asia, particularly through the lens of archaeological site locations relative to geomorphological features. AJG Award from the Association of Japanese Geographers (2017) AJG Award from the Association of Japanese Geographers (2016) Japan Society for Quaternary Research Academic Award (2013) Japan Quaternary Society Best Paper Award (1999) Professor Kubo has led numerous Japan Society for the Promotion of Science research projects, including studies on Indian deltas, river environments and archaeological sites in Indochina, and hazard map development. Her international collaborations with institutions in India, Cambodia, and Vietnam demonstrate extensive fieldwork and research partnerships. While specific student advisees aren't documented in the available materials, her extensive projects suggest active graduate student mentorship. Her research integrates field investigations, laboratory analysis, and geospatial technologies to examine landscape evolution across multiple spatial and temporal scales. Professor Kubo's work frequently involves interdisciplinary teams of archaeologists, geologists, and environmental scientists, particularly in her studies of Southeast Asian archaeological sites and their geomorphological contexts.
