[ International SCI(E) only ]

*Since Prof. LEE joined the PNU in 2017, he has written and published the own papers without collaborations, thus the LEE Lab’s original papers by himself and his students only. So, he believes that this is the only way for the PNU to get its originality internationally, and it is basis to say that this is from our own ability.
