LIU Yijun
Chair Professor
ASME fellow
Department Head

He obtained his B.S. and M.S. degrees from Department of Aerospace Engineering of Northwestern Polytechnical University in 1981 and 1984 respectively. He got his Ph.D. in Theoretical and Applied Mechanics from  University of Illinois at Urbana-Champaign in 1992.  During 01/1992 and 04/1994 he was doing post doc research in Iowa State University. He was an Professor at University of Cincinnati during 09/1996 and 04/2018 and has been a chair Professor at Southern University of Science and Technology since 04/2018. Dr. Liu’s research interests are in computational mechanics, especially modeling of advanced materials (including composites, nanomaterials, biomaterials and MEMS) and wave propagation problems (acoustic and elastic waves). He has been focusing on large-scale modeling of materials/devices at the micro-length scale for which the continuum mechanics based approaches can be employed. He is specialized in the boundary element method (BEM), for which he has devoted his research efforts for more than 20 years.
