Life Summary
Seo Jung-jin is the Chairman of Celltrion Group.

He is pushing to transform Celltrion from a biosimilar company into a new drug development company.

He was born on October 23, 1957, in Cheongju, North Chungcheong Province.

He graduated from Jemulpo High School in Incheon and the Department of Industrial Engineering at Konkuk University, and received a master’s degree from the Graduate School of Industry at Konkuk University.

He began his professional career at Samsung Electro-Mechanics.

He later moved to the Korea Productivity Center, where he was in charge of consulting for Daewoo Motors, and then joined Daewoo Motors as a planning and finance advisor. After the Daewoo Group was dismantled, he founded Nexol, the predecessor of Celltrion, in 1999 with around 10 former colleagues from Daewoo Motors.

While searching for promising future industries, he discovered the potential of biosimilars, or copy versions of biologic drugs, and boldly entered the bio industry despite not having a background in the field.

In 2012, he successfully developed the world’s first antibody biosimilar, Remsima, opening the door to the global market. In 2020, he stepped away from management as Celltrion Group established a professional management system, but returned in March 2023.

Based on his distinctive strong drive, he is leading Celltrion’s business at the forefront.

He is a workaholic who genuinely enjoys working.
