I study how climate variability shapes water systems, ecosystems, and landscapes across timescales. My research integrates paleoclimate proxies, organic and isotope geochemistry, climate modeling, and lake water-quality modeling approaches to connect local environmental records with regional climate dynamics. I am particularly interested in tropical and monsoon regions, where rainfall, runoff, evaporation, and ecosystem responses are tightly linked. By combining natural archives, modern observations, and numerical models, my work aims to improve understanding of climate change and variability, water cycle, and ecosystem resilience in a warming world.
