Professor Satoshi Takizawa's research lab focuses on environmental and water resource management, particularly addressing urban water security and subsidence risks in densely populated regions like Jakarta, Indonesia. The lab investigates groundwater over-abstraction, piped water supply optimization, and the integration of hydrological and geological data to identify priority areas for infrastructure development. Additionally, the lab explores biological systems, including the expression and function of endothelin peptides in the gastrointestinal tract, contributing to understanding intestinal physiology and pathophysiology. The interdisciplinary approach combines environmental engineering with molecular biology to address both societal and biomedical challenges.

Although the special region of Jakarta Province (DKI Jakarta), Indonesia, has a large population of 10.9 million, piped water coverage remains at only 64%. Therefore, excessive groundwater abstraction has caused serious land subsidence over the last few decades. This study proposed the priority areas for piped water supply extension to alleviate the adverse effects of groundwater over-abstraction in DKI Jakarta. Water consumption and multilayer analyses (e.g., geology, groundwater abstraction, g
Endothelin (ET)-2, an ET family peptide, is highly expressed in intestine. However, the specific distribution and function of ET-2 remain unknown. We elucidated the expression profile and localization of ET-2 in mouse gastrointestinal tract. Real-time PCR analysis revealed that ET-2 gene expression in the gastrointestinal tract of healthy animals was relatively high in the colon. Immunohistochemical analysis revealed ET-2-like immunoreactivity mainly in epithelial cells of the mucosa throughout
