Yong Suk Yang is a Professor Emeritus in the Nanoenergy Engineering Department and former Dean of the College of Nanoscience & Nanotechnology, and former Director of the Research Center for Dielectric and Advanced Matter Physics at Pusan National University. He received his BS in physics in 1977 from Sogang University, Seoul, and PhD in solid state physics in 1990 from McGill University, Montreal. He is a faculty member since 1993. He has been carrying out experiments at neutron- and synchrotron radiation- related international facilities, NSLS, APS, SSRL, Oak Ridge (USA), AECL (Canada), SPring8 (Japan), Riso (Denmark), KAERI (Korea). He has published various articles on the phase transitions of structural order-disorder, spin dynamics on low dimensional magnet, glass-crystallization through nucleation and growth, negative thermal expansion. Multiferroics, dielectric relaxation, solid oxide fuel cell, lithium ion battery are also his recent interests. Not only research but he also emphases the importance of education and training. He has taught under and graduate students over 30 different subjects, quantum mechanics, statistics, solid state physics, thin films, electronic properties of materials, thermoelectric, semiconductor, thermal physics, ceramics, dielectrics, modern physics…, during the last 20 years.
