Areas of Expertise

  • Bioinformatics and biomedical computing
  • Computer science
  • Digital media

Professor James Hahn's Laboratory for Advanced Computer Applications in Medicine is engaged in research primarily on the use of simulation, reconstruction, and visualization for surgical training, planning, and computer guidance. Technology from computer graphics and visions are used to generate 3D representations of anatomies, registered, and visualized. Current projects include a simulation, analysis, and training system for neonatal endotracheal intubation procedures, a visualization system that takes into consideration the different needs of the different medical specialties, and non-rigid registration for surface reconstruction.
