Biographical Sketch

Originally from China, Liu completed his undergraduate degree in computational math at Peking University. He then moved to California to pursue a doctorate in mathematics at the University of California, Los Angeles. Liu will be working with the ALE-AMR code to add surface tension. This work is a continuation of his graduate research and a project that he worked on as a NERSC summer student.
