He is the eldest son of Seo Jung-jin, Chairman of Celltrion and its founder.

He was born on August 16, 1984.

He graduated from the Department of Animal Science and Biotechnology at Seoul National University and received both his master’s and doctorate degrees from the Graduate School of Nanoscience and Technology in Life Science Engineering at KAIST (Korea Advanced Institute of Science and Technology).

After joining the Celltrion Life Science Research Institute, he served as head of product planning at the Celltrion R&D Division and as Executive Vice President of Celltrion Skincure, before being appointed CEO of Celltrion Skincure in 2017.

He returned to Celltrion as Senior Executive Vice President and Head of Product Development.

After his father, Chairman Seo Jung-jin, announced his retirement from management, Seo Jin-seok stepped to the forefront by serving as Chairman of the Board of Directors at Celltrion, an inside director at Celltrion Healthcare Holdings, and an inside director at Exdati Therapeutics, a UK biotech company invested in by Celltrion.

Following the 2023 merger of Celltrion and Celltrion Healthcare, he has been leading the company as co-CEO of Celltrion.

Since his father, Chairman Seo Jung-jin, had long stated his intention to separate ownership and management and had drawn a line against succession of control, proving his management capability became the top priority.
