ChM. Dr. Lee Hooi Ling

Associate Professor

Greetings from Nanomaterials Research Group, I am Dr. Lee. I regard myself as a fundamental and applications scientist. I am passionate about mentoring enthusiastic individuals. If you are looking for someone who can nurture you to your best limit, you may consider me as your mentor in your postgraduate studies. Additionally, I am also open to collaborations locally and internationally. On a separate note, I am eager to promote STEM and gender equity in the workplace. Let's work together to achieve a balanced scientific-based community!


  • B. Appl. Sc. (Hons), M.Sc. (USM), Ph.D. (Dublin City University, Ireland)

Areas of Expertise

  • Nanomaterials & Nanotechnology, Green Chemistry, Surface Science


REsearch Interest

I am working on the fabrication of metal oxides (titanium dioxide, tin oxide) and carbon-based quantum dots (N-GQDs, N-CQDs) for wastewater treatments, sensors and drug delivery systems. My approach is gearing towards the green synthesis technique and hopes the research will bring sustainability impactful outcome for our society!
