I am interested in finding out how brain controls movements, how plasticity leads to various types of learning. 
  • Clinically, I meet with persons with movement disorders / impairments to understand their lives and acquire data.  
  • Theoretically, I model the mechanism for such healthy / abnormal movements.  
  • As an engineer, I build virtual and mechanical environments to emulate the dysfunctional movement. 
  • As a data scientist, I analyze the data to classify, learn and predict the patterns for diagnosis, prescription of rehabilitative works needed.   

Research Interests

  • Brain Computer interface / Body-Machine interface (BCI / BoMI)
  • Myoelectric control of prosthetics
  • Prototyping electronic system
  • Multi-scale modeling and simulation of biological system
  • Machine Learning application to neural data
  • To understand how brain works, how it breaks, in the framework of sensorimotor control, memory and learning, to develop rehab strategies
  • To study the effect of bio/neural feedbacks in rehabilitation
  • Assessment of artificial neural stimulation to elicit artificial sensation  
  • Development / assessment of assistive device in rehabilitation engineering
  • Neuromorphic engineering for advanced robotics
  • Locomotive movement science (kinematics / kinetics)
