Korean physicist

Je-Geun Park (Hangul 박제근, Chinese character 朴濟根, born 1965) is a physicist in the Republic of Korea. He is a condensed matter physicist known for his work on wide-ranging problems of magnetism, in particular strongly correlated electron systems. He is credited with discovering a new class of magnetic 2D materials, also known as van der Waals magnets. He has worked as a professor at Seoul National University.

Biography[edit]

He was born on October 14, 1965, in Gosung, Republic of Korea. He is married with one daughter. He graduated from Dae-Ah High School in 1984 and attended the Department of Physics at Seoul National University from 1984 to 1988. After his undergraduate, he went on to do his MSc in the group of Professor Se-Jung Oh and worked on core-levels spectroscopy of Mn dihalides and graduated in 1990. He won a national overseas scholarship from the Korean government in 1989 and went to Imperial College, London, to study PhD under Prof. Bryan Coles, FRS. Before returning to Korea, he spent a few years of stints at Lab. Louis Neel, Grenoble, France and Birkbeck College, London. He worked at Inha University (1996–2001) and Sungkyunkwan University (2001–2010). He moved to Seoul National University as a university professor in 2010 and has since built a world-renowned group with pioneering works on van der Waals magnets. He is currently a professor at the Department of Physics and Astronomy of Seoul National University.

Education[edit]
