Eligible to supervise Masters and PhD - email supervisor to discuss availability.

My core research interest is on the design and development of functional materials for environmental and sustainability applications, covering the water purification and CO2 capture technologies. Additionally, I am also extensively working on the development of characterization methods for 2D materials, particularly for graphene-related 2D materials (GR2Ms), using solid characterization techniques such as TGA, Raman, XPS, microscopy methods and etc.
