My main research interest is to study theoretical high energy astrophysics by means of numerical simulations. Currently I am working on ignition problem of SN Ia, collabrating with Stan Woosley, Gary Glatzmaier and Martha Evonuk. I am also interested in the following explosive process of supernova Ia, in collabration with Stan Woosley, Ann Almgren and John Bell. The main super computers I am running code on include Jaguar at NCCS, Franklin at LBNL and Pleiades at UCSC.
