Hello! 안녕! I am Jason Choi (최지원), a Software Engineer at Match Group based in Seoul.
Before joining Match Group, I was a Research Assistant at Interactive Data Computing Lab, under the supervision of Prof. Jaemin Jo. I also interned at NAVER HyperCLOVA and NAVER Smart Studio.
My research focuses on automating data analysis to make these tasks more accessible to a broader audience. To this end, I design novel algorithms and develop interactive techniques. My work has been published in leading visualization venues, including IEEE VIS, IEEE PacificVis, and EG/IEEE EuroVis.
I received a Master of Engineering degree in Computer Science & Engineering in 2025, and a Bachelor of Science degree in Computer Science Education in 2023 from Sungkyunkwan University.
