Our current works include the studies of the dynamics of Harmful Algal Blooms (HABs), monitoring of HABs, detection, identification and physiological studies of bloom-forming species (Leong et al., 2015). The research team has identified several new records of bloom-forming species in Singapore waters including toxic diatom species which has negative health impact on humans (Tan et al., 2016).
We have successfully tracked bloom movements utilizing autonomous vehicles and optical sensors (Leong et al., 2016). Moreover, recently we have developed a molecular method in detecting and identifying toxic species in the field.
