Younghwan Choi is a master’s student in Geography at Seoul National University, studying how climate change reshapes the habitats of crops and humans across time. His research combines crop-habitat modeling with paleoclimate reconstruction to improve how warm and transitional periods are represented in climate models.
Originally trained in History Education, he became interested in climate–society linkages and later drew inspiration from Professor Axel Timmermann’s work at the IBS Center for Climate Physics, which explores how past climatic shifts transformed crop and human habitats.
His current work focuses on projecting future crop-habitat shifts under climate change and refining CMIP6–PMIP4 model performance through Holocene proxy evidence.
