I am a fish biologist by training and have completed a PhD on the historical impacts of climate change on fish ecology. I am passionate about the aquatic environment and in particular, about the use of otoliths (fish ear stones) and the information that can be gleaned from such tiny structures, such as the age, annual growth rates, migration and environmental factors. I have also been involved in other aspects of marine and freshwater ecology such as coral reef monitoring, seagrass surveys, turtle research, in-situ coral experiments and biofouling surveys. I am particularly interested in Southeast Asia, not only because I grew up in this region, but also because marine fisheries have major socio-economic impacts on food security and human livelihoods, yet is relatively data deficient.
I intend to examine the drivers of fish growth, which ultimately affects fisheries productivity, in Southeast Asia. I am interested in both climate drivers such as the El Niño Southern Oscillation (ENSO) and human drivers such as fishing pressure and fisheries management. How climate change and overfishing affects fish populations require urgent attention in Southeast Asia because of the reliance that people in this region have on seafood for nutrition (hence, food security) and livelihoods. My research makes use of multi-disciplinary methods to look at multiple aspects of the linkages between climate, humans and fish.
