Our research theme is to develop algorithms and applications for discrete structures such as lattices, rings of integers, and point configurations on Euclidean spaces and manifolds, by using tools and theories of geometry of numbers, algebraic number theory, discrete mathematics, convex optimization, and analytical methods related to quadratic forms and diffraction theory of crystals and quasicrystals.
