Je-Geun Park

Je-Geun Park (; born 1965) is a physicist in South 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.

Early life and education He was born on October 14, 1965, in Goseong, South Korea. 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 degree, 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.

Academic career

Je-Geun Park worked at the Institut Néel in Grenoble, France, and at Birkbeck College, London, as a post-doc after getting his PhD from Imperial College, London, in 1993. He then returned to Korea to take up an assistant professor position at Inha University from 1996 to 2000, and was promoted to associate professor in 2001. He then worked as an associate professor at SungKyunKwan University from 2001 to 2006 before becoming a professor from 2006 to 2009 and SKKU fellow from 2009 to 2010. He later moved to Seoul National University in 2010 as a professor. He is currently a director at the Center for Quantum Materials in SNU.
