Area of Science:

  • Molecular Cytogenetics
  • Image Processing
  • Biomedical Imaging

Background:

  • Multiplex fluorescence in situ hybridization (M-FISH) is crucial for multi-color chromosome karyotyping.
  • M-FISH generates complex image sets from specimens captured at various optical wavelengths.
