Dr. Chirlmin Joo


Chirlmin Joo studied physics at Seoul National University in Korea. He obtained his PhD in physics under the supervision of Taekjip Ha at the University of Illinois at Urbana-Champaign, USA. He studied a DNA repair process using single-molecule fluorescence. During his PhD study, he advanced single-molecule techniques by innovating new tools including single-molecule multi-color FRET. As a post-doctoral fellow in Narry Kim’s lab at Seoul National University, Korea, he discovered novel proteins in microRNA biogenesis. As a research professor in the same institute, he succeeded reconstitution of functional protein complexes at the single-molecule level.

He has his faculty position at Delft University of Technology in the Netherlands. He applied the single-molecule FRET to mechanistic studies on the target search process of microRNA and CRISPR/Cas9 and the single-molecule pull-down method to the functional studies of protein complexes in microRNA biogenesis and CRISPR memory formation.
