My group at the National University of Singapore is focused on developing functional materials for various applications. Ongoing projects involve the exploration of molecular interactions and their behavior at the interface of material, environment, and human health. We have published more than 300 papers (H-index 61) with 18,900 citations. I am also on the editorial boards of journals such as Scientific Reports, MRS (US) Communication, Prism - Plastics (Cambridge Univ. Press), Nanomaterials (MDPI), International Journal of Molecular Science (MDPI), Cancer Nanotechnology, Frontiers in Marine Science etc. Some of the ongoing projects in the groups include the functionalization of natural polymers (e.g., cellulose), the development of new adsorbent materials (e.g., polymers, metal oxides, biomembranes) for water purification, the safety and toxicity of metallic nanoparticles and microplastics, and the investigation of biomimetic synthesis of hard tissues (e.g., eggshells, seashells).
