My research interests are in the theory of rings and modules. Here are a few most recent representative publications:
 Morphic rings and unit regular rings, (with TK. Lee), J. Pure Appl. Algebra 210(2007), 501510.
 Group rings in which every element is uniquely the sum of a unit and an idempotent, (with J. Chen, W.K. Nicholson), J. Algebra 306(2006), 453460.
 Continuous modules are clean, (with V.P. Camillo, D. Khurana, T.Y. Lam, W.K. Nicholson), J. Algebra 304(2006), 94111.
 Morphic group rings, (with J. Chen, Y. Li), J. Pure Appl. Algebra 205(2006), 621639.
 Clean general rings, (with W.K. Nicholson), J. Algebra 291(2005), 297311.
 Strong lifting, (with W.K. Nicholson), J. Algebra 285(2005), 795818.
 Classes of Modules, (with J. Dauns), Pure and Applied Mathematics, a Series of Monographs and Textbooks, 281, ChapmanHill/CRC Press, 2006.
