Joo Youngsung

Joo Youngsung is an Associate Professor in the Department of BIO at Seoul National University. His research focuses on ecological interactions, particularly tissue-specific plant defense against specialized insect herbivores. He investigates ecological factors enabling complex plant-herbivore interactions, the functional consequences of tissue-specific defense, and how plants shape these interactions. His approach combines interdisciplinary methods, including molecular biology and analytical chemistry, with field and common garden experiments. Joo's work addresses the Darwinian fitness consequences of heterogeneous plant-herbivore interactions in nature.

Youngsung Joo's research focuses on Plant-insect interactions, Chemical ecology, Metabolomics, and Plant volatiles. Their work explores how plants defend against herbivores through volatile emissions and metabolic responses, with a particular emphasis on circadian rhythms and signaling pathways. Joo's studies reveal how plant volatiles mediate indirect defense against herbivores and how metabolic changes under stress influence plant-herbivore dynamics. Research also examines the role of circadian clocks in regulating plant defense mechanisms and how environmental factors like climate change impact these interactions. Key findings include the role of genes like LHY, ZTL, and TOC1 in modulating plant responses to herbivory and environmental stress.
