Hear about my research: Sounds of science
What do I do?
I study environmental contaminants:
- How they get into the environment?
- What happens to them?
- How do they behave under relevant environmental conditions?
- How do they evolve or transform?
Over the past years, my research interests have been on nanomaterials. These are examples of contaminants of emerging concern. I have been investigating the fate and behaviour of these materials in the environment, particularly, nanomaterials based on silver, carbon (e.g. fullerenes), quantum dots, and metal oxides. These are studies that are necessary in the assessment of their potential environmental risks.
Why I think it matters?
Assessment of environmental risks is important in making sure that applications of nanotechnology is developed and utilised safely. By doing these studies, we help regulatory bodies come up with appropriate rules and guidelines to protect us and the environment.
Why do I do it?
I decided to pursue research in environmental chemistry because I think we owe it to ourselves (and to the next generations) to take care of the environment that we live in. I "research" because I enjoy the scientific process...thinking of a problem, having a hypothesis, designing experiments, followed by conducting experiments to test our hypothesis.
What am I doing now?
I have now also started to do research in using nanomaterials for applications in remediation and agriculture. I want to use what I have (so far) learned on the environmental implications of nanomaterials in contributing to the development of these applications with safety in mind.
