Mangrove ecosystems are among the most efficient natural carbon sinks and play a critical role in regulating the global climate. Our research investigates the microbiomes of mangrove sediments, focusing on their dynamic roles in carbon cycling and their responses to environmental stressors such as climate change and pollution. By understanding how microbial communities contribute to carbon sequestration and greenhouse gas emissions, we can better grasp the resilience and vulnerability of mangrove ecosystems.
We apply an integrated suite of advanced techniques—including metagenomics, metabolomics, and controlled microcosm experiments—to explore how microbial-mediated carbon and nutrient cycling varies across diverse mangrove locations and sediment depths. Our studies aim to identify the key microbial taxa and metabolic pathways involved in these processes, while also examining how environmental changes, including pollutant exposure, influence microbial metabolism and gene expression.
Through this work, we seek to generate actionable insights. These include the development of biotechnological tools to enhance carbon sequestration and rehabilitate polluted mangroves, as well as the generation of robust microbial datasets to improve climate models and guide environmental policy. Ultimately, our findings aim to support more informed and effective mangrove conservation and restoration strategies—ensuring the long-term health of these critical coastal ecosystems.
Antimicrobial resistance (AMR) is a growing global health threat impacting human and environmental health. Our research investigates the prevalence and spread of AMR in diverse environments, adopting a One Health approach to understand the interconnectedness of AMR across different domains.
Our lab is actively involved in international and national efforts to monitor and understand the dynamics of AMR in urban environments, including in public spaces and hospital settings. These studies provide valuable data for assessing the risks associated with AMR, particularly in environments where antibiotic use is high, such as hospitals, and informing strategies to mitigate its spread.
Recognising the importance of mangrove ecosystems in maintaining environmental health and the potential for AMR dissemination in these environments, our AMR research also extends to mangrove ecosystems. We examine the prevalence of AMR genes in mangrove sediments and water, and the potential for transmission of AMR between mangrove ecosystems and human populations. By studying AMR in mangrove ecosystems, we aim to contribute to a more holistic understanding of this global challenge.
Beyond our core research, we actively explore the role of microbial communities across various environments, including terrestrial soil, water and biological samples. We seek to understand their roles in ecological processes and to develop innovative applications. For example, we study soil microbiome dynamics associated with animal decomposition to estimate postmortem intervals, applying our knowledge in soil microbial ecology to forensic science. Other examples of microbiomes we look into include wastewater, coastal, and insects. We welcome collaborations with industries and researchers seeking to leverage the power of microbiome science for different applications.
