I'm excited to share two pieces of good news from CHI 2026!

First, my paper "CHOIR: A Chatbot-mediated Organizational Memory Leveraging Communication in University Research Labs" was accepted with minor revisions at CHI 2026! CHOIR explores how everyday conversations can become organizational knowledge, where questions reveal gaps in documentation and answers become shared resources. We found that AI can facilitate rather than replace human communication, while also uncovering a tension between individual privacy and organizational awareness.

Second, I received Outstanding Reviewer Recognition for all three papers I reviewed as an external reviewer for CHI 2026! It was an honor to contribute to the review process and help maintain the quality of research in the HCI community.

I'm grateful to my advisor Prof. Sang Won Lee, my co-authors Adnan Abbas, Yan Chen, and Young-Ho Kim, and the echolab for their support throughout this research.

I traveled to Yokohama, Japan for CHI2025 as a Photography SV, continuing my role from CHI2024. This year, I also served as the leader of the Videography team, where I led the production of short-form interview videos featuring conference attendees.

Our team created engaging content that captured the diverse perspectives and experiences of CHI2025 participants. These videos were featured on the ACM CHI Instagram account, sharing the vibrant energy and community spirit of the conference with a broader audience.

Additionally, we organized an interactive photo event where attendees could take commemorative photos with an Instagram-style frame. This event became a popular spot for participants to capture their CHI2025 memories and connect with fellow researchers.

While I didn't have a publication to present this year, I'm looking forward to the possibility of returning to CHI as a presenter in the future with my own accepted work. Participating as a Student Volunteer continues to be an incredible opportunity to connect with researchers from around the world and contribute to the HCI community.

I'm excited to announce that I've joined the Echolab at Virginia Tech as a Ph.D. student, working with Prof. Sang Won Lee.

Echolab's mission is to explore and develop methods to foster empathic interactions among individuals using computational systems. The lab focuses on three key research themes: computational tools for perspective sharing, computers as an expressive medium, and the facilitation of empathic communication. The lab also studies how to create safe environments where people can be vulnerable.

Echolab is a platform where members develop into independent researchers, a community where inclusion is prioritized, and a place where collaboration and learning from each other are valued.

I'm looking forward to contributing to the lab's research in human-computer interaction, particularly in accessibility, social computing, and human-AI interaction.

I traveled to Honolulu, Hawaii for CHI2024 as a Photography SV, determined to show what the conference truly feels like. Instead of just taking photos, I recorded footage using a smartphone, action camera, FPV drone, and a 360° camera, capturing the full spirit of CHI. To set the right mood, I used Suno AI to generate a custom soundtrack themed around Hawaii and CHI2024.

The video was a hit among fellow Student Volunteers, and I had the honor of showcasing it at the Closing Keynote—a moment I’ll never forget. It’s now featured on the CHI2024 homepage, letting anyone get a glimpse of the event’s energy.

Participating as a Student Volunteer gave me the chance to meet incredible people from around the world, exchanging ideas and research in the HCI community. I look forward to finding more ways to share the CHI experience!

During my summer visit to the University of Notre Dame, I visited the University of Toronto. I was lucky to be invited by PhD student SuHyeon Yoo to give a guest talk in her group, Dynamic Graphics Projects (DGP).

I gave a talk titled "Leveraging NLP Models in Practice", which introduced the ModSandbox research I published at CHI2023 and the TOMAS research I was doing during my summer visit.

Thank you very much to all the students and SuHyeon for listening to the talk.

After meeting and talking with Toby Li at CHI2023, I got the opportunity to visit his lab at the University of Notre Dame this summer. He warmly welcomed me and even celebrated my birthday.

I engaged in enthusiastic discussions and collaborated with two Chinese undergraduate interns he introduced, working on implementing TOMAS (Task-Oriented Multimodal Agent System).

While it's not yet complete, I plan to conduct additional user studies back in Korea and write a paper on it.

My first paper, "ModSandbox: Facilitating Online Community Moderation Through Error Prediction and Improvement of Automated Rules," was accepted in CHI 2023! I collaborated with Jean Y. Song in 2019 Fall to publish a study about the system for online community moderators to configure their rule-baed moderation tools. The paper was rejected in CHI 2022 and CSCW 2022 and finally accepted in CHI 2023. Thanks to our advisor, Juho Kim, and co-authors, Jisoo and Mina. Also, I would like to thank Prof. Insik Shin for supporting me in continuing my research.

I helped to run the booth of Fluiz, a startup founded by my advisor, Insik Shin. I worked as a software engineer in the 2022 Fall and Winter. Our company won the CES 2023 Innovation Awards in the Software & Mobile Apps at CES 2023. We ran a booth at the KAIST section. I contributed to the process of winning the award and preparing the booth. Also, I explained our product, FLUID: Next-generation Multi-device Mobile Platform) to the people in the industry. It was a very valuable experience.

I attended UIST 2022 to present my UIST poster LV-Linker!

I met several enthusiastic researchers in the HCI field and shared my research ideas and directions. Especially, I made a lot of social connections with graduate students who have the same interests.

I'm selected as a Gary Marsden Travel Awardee, a travel support award of ACM SIGCHI. Thanks to the committee who give me financial support to attend on-site UIST 2022! I'll present a poster and meet a lot of people!

We designed and evaluated LV-Linker (Log and Video Linker), a web-based data viewer system for synchronizing both smartphone usage log and video data to help researchers quickly to analyze and easily understand user behaviors.

Thanks to my co-authors, Hansoo Lee, Youngji Koh, and Prof. Uichin Lee in KAIST!
