Adjunct Instructor

As a chemist interested in the material science field, I explore industrially feasible routes to produce synthetic carbon nanomaterials adapting to simple one-pot mixing recipes. The ultimate goal is to significantly reduce the production cost in the bulk synthesis of advanced carbon nanomaterials.

These carbon nanomaterials would have promising applications in:

  • capturing of greenhouse gases such as carbon dioxide
  • environmental remediation – water purification
  • energy storage – Li-ion batteries and supercapacitors

Education

  • Ph.D., Chemistry, Kent State University
  • B.Sc., Chemistry, University of Peradeniya, Sri Lanka

Research Interests

  • Activated carbon spheres
  • Graphitic carbon nanomaterials
  • Supercapacitors
  • Carbon dioxide capture
