Jaejun Yu is a South Korean professor of physics at the Seoul National University.

Early life

Jaejun Yu was born in 1962. He obtained his Bachelor of Science degree in physics from Seoul National University in 1984. From 1986 to 1988 he attended Northwestern University along with A. J. Freeman,[1] where he got his Master's and Ph.D.. From that year on, he worked as Research Associate at his second alma mater for two years. From 1991 to 1992 he held the same position at the University of Illinois and then became Assistant Professor Sogang University which was followed by becoming an Associate Professor at the same place. Since 1999 he works at Seoul National University where he held numerous positions including being a member of Center for Theoretical Physics, Center for Strongly Correlated Materials Research (ended in 2014), and Interdisciplinary Program in Computational Science and Technology (since 2004), being first Assistant, then Associate, and then becoming Professor of Department of Physics and Astronomy, and even working as associated dean between 2014 and 2016 for Faculty of Liberal Education at the same institution. In 2006 was appointed as Local Program Committee's secretary at the 10th Asia-Pacific Physics Conference. For a brief year (2007) he was appointed as executive editor of Journal of the Korean Physical Society and since 2012 is an Associate Editor for Philosophical Magazine and its subsidiary, Philosophical Magazine Letters. From 2010 to 2011 he was a visiting scientist at the National Renewable Energy Laboratory and in summer of 2012 became visiting professor at the Institute of Scientific and Industrial Research of Osaka University. From 2014 to 2016 he worked as General Council Member for Asia Pacific Center for Theoretical Physics and treasurer the Korean Physical Society.[2]

Research

In 1987 while attending Northwestern University, he, A. J. Freeman, and J.-H. Xu published an article in Physical Review Letters which explained the electronic structure of tetragonal crystal system and how barium and strontium suppress and stabilizes its phase.[3] The same year he along with S. Massidda, A.J. Freeman and D.D. Koelling have published study where he combined two 2-dimensional copper(I) oxide and two 1-dimensional Cu1-O to construct an electronic band structure[4] following by fermi energy study.[5]
