Professor In-Gyu Choi's research lab specializes in sustainable biomass conversion and biorefinery technologies, focusing on the valorization of lignocellulosic biomass such as *Eucalyptus pellita*. The lab investigates innovative chemical and biological processes—including organosolv lignin extraction, enzymatic and fungal biotransformation of terpenes, and alkaline pretreatment—to enhance the efficiency of producing high-value chemicals, biofuels, and functional oligosaccharides. A key research direction involves understanding and manipulating biomass recalcitrance through structural modification of cellulose, hemicellulose, and lignin. The lab also explores the role of microbial and fungal biocatalysts in selective transformation of natural compounds.

In general, lignin exhibits unpredictable and nonuniform thermal properties due to the structural variations caused by the extraction processes. Therefore, a systematic understanding of the correlation between the extraction conditions, structural characteristics, and properties is indispensable for the commercial utilization of lignin. In this study, the effect of extraction conditions on the structural characteristics of ethanol organosolv lignin (EOL) was investigated by response surface meth
The authors tested the hypothesis that East Asians, because of their holistic reasoning, take contradiction and inconsistency for granted and consequently are less likely than Americans to experience surprise. Studies 1 and 2 showed that Korean participants displayed less surprise and greater hindsight bias than American participants did when a target's behavior contradicted their expectations. Studies 3 and 4 further demonstrated that even when contradiction was created in highly explicit ways,
