Biography

I have built my career around the study and teaching of chemical ecology and animal behavior, passions that began during my undergraduate studies in Korea. My fascination with animals is driven by a desire to understand their behaviors in nature and the underlying reasons for these actions, which extends to a broader curiosity about human behavior and society, including my own. I am deeply committed to student mentorship, guiding students through research that often leads to academic recognition and awards. Since the beginning of my graduate studies, as a graduate teaching assistant, I have embraced the idea that "teaching is the best way of learning," finding joy in helping students expand their understanding of nature through shared experiences. In addition to teaching, I am actively involved in professional organizations such as the Animal Behavior Society. Outside of my academic pursuits, I enjoy spending time outdoors, particularly hiking and camping, as a way to connect with nature—an interest I have had since my teenage years.

Research Interests

My research focuses on olfactory communication in foraging, mating, and reproduction, using earthworms, fishes, and insects as model systems. My work has included studying the ant-plant mutualism in Korea, exploring pheromone communication and its role in reproduction in moths in Kansas and Florida, and investigating chemical ecology and reproductive communication in Cyprinid fishes, such as goldfish, common carp, and invasive carps in Minnesota. Through these diverse projects, I aim to deepen our understanding of how animals interact with their environments and each other through chemical signals.
