My name is Sunghwan Yi, and I am a full professor at the Department of Marketing and Consumer Studies at the University of Guelph. Beginning my professor career in 2004, I have been conducting research on consumer behaviour in several domains from the perspective of psychology and behavioural science.
Overall, I am interested in why people keep over-consuming certain products (or become addicted to them) and under-consuming others (or cannot increase their consumption of them) in spite of knowing that doing so is not good for themselves and others around them.
On the over-consumption side, my research programs include motivational and situational factors behind individuals engaging in excessive buying and gambling as well as their difficulty in exercising self-control. On the under-consumption side, my research programs include identifying situational factors that make it difficult for individuals to choose or consume healthy and sustainable foods, such as fruits, vegetables and legumes, and using these findings to gently “nudge” them toward these items. Furthermore, I am collaborating with institutional food services to help them find better ways of offering more healthy and environmentally sustainable food that are mouthwatering as well.
I strongly believe that my research on healthy food and addictive behaviours are relevant to promoting consumers’ well-being in the ever-complex world cluttered with cues eliciting temptations and instant gratification. I am also a strong believer in multi-disciplinary research. I have closely worked with researchers in the fields of clinical psychology, behavioural addictions, human nutrition, environmental science, public health, etc.
