Pai's current research is focused on understanding the principles used by the brain and the musculoskeletal system to control and sense movement. The goal is to develop a constructive (and not just a descriptive) understanding, which can be tested with realistic, large scale, computational models of the neuromechanical systems of humans and other animals. The computational models we develop also have applications in diagnosis and treatment of sensorimotor pathologies (such as spinal cord injury and strabismus), more realistic computer animation, and construction of robots with human-like capabilities.
Previous research in the lab addressed similar problems, but was more focused on physically based computer animation, haptic interaction, auditory displays, and robotics. These areas still play an important role in our constructive approach to understanding sensorimotor biology.
