Dr. Myoung-Jin Chae

Welcome! I am currently an Assistant Professor of Marketing at Sejong University in Korea. Before joining Sejong University, I worked as an Assistant Professor of Marketing at Soonchunhyang University (Korea) and Lingnan University (Hong Kong). I received my Bachelor's degree in Statistics and Business Administration (Korea University), an M.A. in Statistics (Columbia University), and a Ph.D. in Marketing (Georgia Institute of Technology). My research focuses on Human–AI Interaction, AI Trust and Delegation, Consumer Responses to Emerging Technologies, Technology and Consumer Meaning, and Human Control and Agency. 

What I Study:

I study what happens when good technology meets complicated humans. A product may be objectively better but feel less meaningful; people may trust AI yet still want to check its answers; consumers may support a social value but choose differently when their own interests are at stake.

The Problem I Care About:

My research begins with the gap between what firms expect consumers to do and how people actually think, feel, and choose. I am especially interested in situations where seemingly reasonable assumptions about technology, trust, value, or choice break down.

Why It Matters:

As a marketing researcher, I aim to uncover these hidden frictions so that firms can make better decisions about how technologies are designed, positioned, communicated, and ultimately translated into real consumer value.

In teaching, I emphasize practical, data-driven problem-solving and the connection between conceptual understanding and real-world decision making. I currently teach Marketing Management at both the undergraduate and MBA levels, Marketing Research for undergraduate and MS/PhD students, and AI Analytics for undergraduates. Across these courses, I focus on developing students’ analytical skills, critical thinking, research literacy, and ability to apply marketing concepts and data to practical business problems. My previous teaching has also included Digital Marketing, International Marketing, Data-Driven Marketing, Social Research Methods, and Statistics.

Ultimately, I aim to help organizations make better decisions by understanding how people actually respond to new technologies, products, and market choices. Through my research and teaching, I seek to bridge technological innovation with human judgment and consumer value, helping firms create solutions that are not only more advanced and efficient, but also more meaningful, trustworthy, and aligned with the people they are designed to serve.
