Welcome to the COHRINT (“coherent”) Lab!

Professor Nisar Ahmed’s research explores new algorithms and models for probabilistic reasoning that promote cooperative intelligence in mixed teams of humans and autonomous robotic vehicles. The COHRINT Lab blends this cutting-edge theory with real-world robotic software and hardware. nisar_prof_headshot

Key problem areas for aerospace applications include:

  • integrated sensing, perception, planning and control in human-robot teams
  • learning and prediction of human/autonomy decision making and task performance
  • fusion of complex information in dynamic sensor networks
