About

Sungjae Hwang investigates the intersection of human-robot interaction and food science, focusing on how automation reshapes consumer experiences in the food service industry. His research uniquely combines sensory science, consumer psychology, and emerging technology to evaluate robotic systems in hospitality settings. Hwang’s most-cited work, a 2023 study comparing robot versus human baristas, analyzed volatile compound profiles via GC-MS alongside consumer acceptance, sensory perception, and emotional responses to brewed coffee—garnering 10 citations for its pioneering approach to understanding how automation affects product quality and consumer attitudes. In a 2024 eye-tracking study, he further explored consumer attention to coffee brewing robots, using gaze behavior data to compare perceptions of robot and human baristas, contributing valuable insights into visual engagement with service robots. Hwang’s work is notable for bridging technical food chemistry with behavioral research, offering practical implications for the growing trend of automation in food service. His findings help inform how robotic integration can maintain or enhance consumer satisfaction, making his research essential for scholars studying technology adoption, sensory evaluation, and the future of hospitality.
