Yoonjin Lee Professor
Department of Mathematics/Scranton Honors Program
Professor Yoonjin Lee received her Ph.D. degree at Brown University in the area of Number Theory under the supervision of Prof. Michael Rosen. She worked as a professor at several universities in US and Canada such as Arizona State University, University of Delaware, Smith College, and Simon Fraser University for eight years. Currently, she is a professor of the Mathematics department (since 2007) of Ewha Womans University, which is the largest women institution nationwide and it is her alma mater. She worked as the Vice President for Admissions of Ewha Womans University (20172021). She also worked as a chiefineditor of "Bulletin of the Korean Mathematical Society", which is a SCI(E) international journal (20172018), and now she still works for the journal as an associate editor. Furthermore, she worked as a leader of BK 21 plus team ("Mathematical Science Team for Global Women Leaders") (20132019) and as chair of the Math department and Head of Division of Mathematical and Physical Sciences (20112013) at Ewha Womans University. In 2018, she was awarded "The 7th Award for the SOIL Excellent Research Paper", which was offered by KAST (The Korean Academy of Science and Technology), and she received the "Best Teacher Award" from Ewha Womans University in 2009. Her primary research interests are in Number Theory and Algebraic Coding Theory, and she has published about 100 research papers in SCI journals.
