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
