Worked in the Biomedical Functional Imaging and Neuroengineering Laboratory under the mentorship of Professor Bin He.Configured an interface between BCI2000 and a Jaco mechanical arm device. The interface was written in C#, and allowed for communication between a subject's brain waves and the movement of the mechanical arm. By focusing their attention on a particular motor imagery signal, subjects could control the robotic arm with their mind.
