Woojin (Jay) Park

Co-Founder, CEO & Chief AI Scientist at insightea

I lead AI research and platform architecture for personalized news, recommendation, and agentic reasoning at insightea. I am also a fourth-year Ph.D. candidate in Industrial Artificial Intelligence at Korea University, advised by Prof. Taesu Cheong in the SaVAnNA Lab.

My work spans recommender systems, user modeling, large language models (LLMs), algorithmic auditing, and reliable AI. I connect research in measurement and evaluation with production machine-learning systems in news, healthcare, and large-scale consumer platforms.

I received an M.S. in Data Science from Carnegie Mellon University after graduate study and research at Syracuse University in the Science of Science & Computational Discovery Lab, led by Prof. Daniel Acuna. I bring more than a decade of industry experience in data science, applied AI research, and technical leadership, including roles at Hyundai & Kia Motors Group, IQVIA, Coupang, and Catchtable.

I am exploring opportunities in applied science, data science, and AI research, including technical leadership roles and postdoctoral positions, with a flexible start date in the first half of 2027. I would be happy to connect and discuss potential opportunities.
