Research

Naoki Saito’s research focus has been on applied and computational harmonic analysis, which is a discipline to study:

  1. efficient, meaningful, and interpretable representations of data objects (e.g., signals and images) and operators (e.g., singular integral operators) defined on various domains (e.g., regular lattices; manifolds; or graphs);
  2. fast computational algorithms to operate on them; and
  3. their wide-range applications including those in computer science, electrical engineering, geophysics, neuroscience, and statistics.
