Hello! 안녕! I am Jason Choi (최지원), a Software Engineer and Research Scientist specializing in Information Visualization and Human-Computer Interaction (HCI). I previously served as a Research Assistant at the Interactive Data Computing Lab, under the supervision of Prof. Jaemin Jo. My industry experience includes internships as a Research Engineer at NAVER HyperCLOVA and as a Frontend Software Engineering Intern at 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, leveraging algorithms such as deep learning, and develop interaction techniques. My work has been published in leading visualization venues, including IEEE VIS, IEEE PacificVis, and EG/IEEE EuroVis. I am also passionate about translating my research into practical, open-source software using modern web technologies.
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.
