My research focuses primarily on the breeding, grow-out culture, and genetic studies of crustaceans especially crabs and shrimps, to study their genetic inheritance, diversity, grow-out culture and  feasibility to be the local brood stocks candidate for aquaculture production. I look into the phylogenetics and evolution of brachyuran crabs using various methods, including mitochondrial genes, nuclear genes, mitochondrial genome and gene families, and single copy gene derived from transcriptome data. Besides, I am also interested on the uniparental inheritance (maternal and paternal) of crustaceans in mitogenomic aspect. Furthermore, from the previous research, I described the population dynamics of all mud crab species in the wild and found the occurrence of presumed hybrid mud crabs in the equatorial region. I found and described four presumed hybrid groups that are morphologically distinct compared to the original four Scylla species. I also tested the feasibility of inter-species mating and discovered that crosses between Scylla species is easily induced in captivity. This further increases my interest to investigate the potential effect of climate change (increase in seawater temperature) in inducing the occurrence of presumed hybrids of Scylla in the wild. In conclusion, my research interest and focus are important in the selective breeding program of crustacean aquaculture and also important in the future prediction of crustacean aquaculture amid global warming.
