Biography

Changsun Ahn is an Assistant Professor in School of Mechanical Engineering at Pusan National University. He received his Ph.D.(2011) in Mechanical Engineering from the University of Michigan, USA, M.S.(2005) and B.S.(1999) in Mechanical Engineering from Seoul National University, South Korea. He worked at Korea Institute of Machinery and Materials from 2012 to 2013 and was in charge of design control systems for magnetic levitation applications. He worked for Hyundai Motors from 2005 to 2007 and developed integrated chassis control systems to improve vehicle safety and performance. During his doctoral program, he studied on state estimation for automotive applications and the charging control of plug-in electric vehicles on the Smart Grid. His research interests are the modeling and control of automotive systems and energy systems.
