    • Foil journal and thrust bearings
    • Herringbone-grooved journal and spiral-grooved thrust bearings
  • High-speed rotor design
    • Rotors between 1e6 to 3e6 mmrpm (rotational speed in rpm times the rotor diameter in mm) successfully tested
    • Rotordynamics
    • Rotor mechanical integrity
    • Rotor thermal analysis
  • High-speed rotor balancing
  • Small-scale turbomachinery design
    • Compressors, blowers, and fans
    • Turbines
    • Turbochargers
  • Integrated system simulation (including detailed turbomachinery and bearing modeling)
