AREAS OF SPECIAL INTEREST

Dr. Sergi is the director of the Human Robotics (HuRo) lab at the University of Delaware.

Research in the HuRo lab aims to achieve the dual goals of developing and validating robotic technologies for human assistance and rehabilitation, and of using such novel technologies in experimental studies modeling the healthy and impaired human motor control.

Example areas of interests of the HuRo lab include:

  • the combination of high-fidelity haptic feedback devices with neuroimaging to study the neural substrates of motor control;
  • the development of energy-recycling wearable orthoses for gait assistance and augmentation;
  • the development of high performance compliant actuators and interaction controllers.
  • the implementation and validation of robotic assistance schemes in neurorehabilitation
