Hi, I am Jeesun Oh. I study human-computer interaction and design digital products.

While pursuing my Ph.D. at ID KAIST, I studied voice user interfaces, specifically regarding voice characteristics, proactive verbal communication, and visual feedback in voice interaction. I completed a double major in Human Environment and Design (BA) and Business (BBA) at Yonsei University and earned a Master's degree in Digital Design and Branding (MSc) from Brunel University in London, UK. I have work experience as a temporary team member for Google ATAP, focusing on a wearable band that tracks users' physiological states and gesture interactions, as well as designing an app to visualize physiological data. I also worked as a UX/UI designer at a digital product agency, where I designed a variety of digital products across platforms, including web, mobile, tablet, and TV. After completing my Ph.D. as an HCI researcher, I am currently seeking opportunities to continue my research in human-computer interaction, with a primary focus on voice interaction, expanded to include multimodal approaches that integrate gesture and visual modalities. I am also keen to explore applications in robotics and conversational agents for cars, smart homes, and public spaces.

Publications & Research Fund

My research interests lie in Conversational UX and Voice UX within the field of HCI (Human-Computer Interaction). I aspire to continue my research to contribute to the advancement and design of future interactions between AI and users. Particularly, I seek to explore insightful design implications that balance machine-like and human-like characteristics in conversational agents, considering their new ontology.

Beyond Work


In my personal time, I enjoy engaging in active pursuits that help me relieve stress and bring energy to my life. On a daily basis, I try to incorporate activities like yoga, running, and strength training into my routine. I also embrace the seasons by taking part in activities like golf, diving, and snowboarding. I love traveling to different countries to broaden my horizons and gain new experiences. I find inspiration in nature, architecture, design, and the creativity in art.
