My research focuses on design and evaluation of cost-effective water/sanitation technologies and interventions to reduce environmental pollution and improve public health and wellbeing. 

Research areas:

(1) Advancing developments in water treatment technologies

(2) Exploring interlinkages in the water nexus

(3) Promoting improvements in sanitation, hygiene and health 

Research interests:

- Removal of micropollutants (e.g. microplastics/microfibers, pesticides, pharmaceuticals and personal care products, PFOS/PFAS) from water

- Ecological processes e.g. s slow sand filtration, biosand filtration, ecological purification system, constructed wetlands, vertical hydroponics

- Photocatalysis and photolysis

- Adsorbents e.g. biochar, GAC/PAC

- Small scale microbial fuel cells for wastewater remediation

- Container-based sanitation

- Decentralised and closed-loop technologies

- Water reuse technologies and strategies

- Climate change adaptions

- Nature-based solutions

- Sanitation associated risks and diseases
