Research Interests:

My research interest changed from the theoretical and computational study on nuclear fusion with intense lasers as application of science to that on pioneering a new fundamental science field called Laboratory Astrophysics (LA). LA is to study a variety of plasma astrophysical phenomena in laboratory with use of large-scale lasers and ultra-intense lasers originally developed for laser fusion by realizing a miniature Sun in laboratory; this means they can be also used to study of stellar physics and many of extreme plasma phenomena in Universe. If the basic equations are the same between laser plasma and astrophysical plasma, a computer does not know which physics it is solving. LA is a new method to study astrophysics experimentally. LA provides a good test bed for numerical astrophysics at first. The second interest id to find new physics in LA experiments which we did not expected before the experiment. Thirdly, we can also expect to predict new phenomena in Universe based on the experimental evidence and computational analysis. As the result, we can also provide exciting and challenging subjects in nonlinear and relativistic plasma physics. Both phenomena in laboratory and in Universe are speculated to be controlled by the same physics, regardless of how large scale down in time and space we do in LA model experiments.
