Guoqing (Harry) Xu    Ph.D Student, 2005 Sept. - 2011 June (expected)    Department of Computer Science & Engineering    The Ohio State University, Columbus, Ohio    xug at cse dot ohio-state dot edu   http://www.cse.ohio-state.edu/~xug

My primary research interests are static and dynamic program analyses for compiler optimization and software engineering tasks. In particular, my static analysis interests include pointer analysis, control flow/data flow analysis, and abstract interpretation, while my dynamic analysis interests include just-in-time compilation, dynamic optimization for large (framework-intensive) applications, and parallelism for multicore systems.

I have been working with Dr. Atanas Rountev since 2005. . Prior to joining Ohio State, I received both my M.S. and B.S. with distinction in Computer Science from East China Normal University, Shanghai, P. R. China. Both my M.Eng. thesis and my undergraduate thesis won best (Master and Undergraduate) thesis awards of the year in the Computer Science Deparment, ECNU.
