Her research group has been actively involved in areas related to energy and environmental applications including solar fuel generation and water treatment. One of her research focuses is the development of nano-engineered particulate semiconductor photocatalysts, molecular complexes and hybrid systems for conversion of solar energy to chemical energy via photocatalytic water splitting and carbon dioxide reduction to hydrocarbons and oxygenates. Her group designs efficient inorganic co-catalysts and metal complex catalysts with appropriate interface with the photosensitizers to achieve efficient light absorption, charge separation and utilization. She has completed several projects in these areas as PI with a total value of more than S$5 million from funding agencies such as Agency for Science, Technology & Research (A-Star), Ministry of Education, National Environmental Agency. Currently her work is funded by National Research Foundation through the CREATE Programmes and ExxonMobil Research and Engineering Company. To date, she has published over 140 papers in top tier journals including Advanced Materials, Science Advances, Energy & Environmental Sciences, Journal of the American Chemical Society, ACS Nano, etc. She received Top-Cited Papers for 2010 and 2011 Award from Elsevier, New York, USA for her paper on supported cobalt oxide catalysts for water treatment published in Applied Catalysis B: Environmental. She is currently an Associate Editor the Beilstein Journal of Nanotechnology.​
