Current Research Interests：

Prof. Chiu's research concentrates on the exact chiral symmetry on the lattice, and its applications in lattice QCD, as well as chiral gauge theories. Recently, Prof. Chiu has shown that the conventional lattice domain-wall fermion does not preserve the chiral symmetry optimally for any finite number (Ns) of sites in the 5-th dimension, and proposed the optimal lattice domain-wall fermion [1] which preserves the chiral symmetry optimally for any Ns. Thus the theoretical problem how to construct a domain-wall fermion action such that the effective 4D lattice Dirac operator preserves the chiral symmetry optimally has been completely solved.

Besides theoretical formulations of lattice gauge theories, Prof. Chiu is also performing the state-of-the-art numerical calculations on lattice QCD, with a Linux PC cluster (currently 54 nodes) which were built with off-the-shelf components. The substained computing power of the PC cluster is 60 Gflops.
