I am a marine biologist. My research interests are broadly focused on fisheries interaction, biology, and trophic ecology of pelagic fishes using electronic tags and stable isotope analysis. In particular, my research program is investigating the population dynamics of billfish using pop-up satellite archival tags (PSATs) to study their vertical and horizontal movement patterns, habitat preferences, migration corridors and thermal niche. I also serve as a Taiwan fisheries scientist in the Billfish Working Group (BILLWG) of the North Pacific Tuna and Tuna-like International Scientific Committee (ISC), and have led the implementation of international cooperation for twenty years. Our tagging work makes up for the lack of independent fishery data in the process of establishing resource assessment models. I am also responsible for the implementation of Ocean Conservation Agency (OCA), Ocean Affairs Council of Taiwan. Our mission is to “Pay Tribute to the Sea" in the Taiwan Marine Ecological Environment Protection Plan". Satellite tracking of marine wildlife is particularly critical to learn the habitats of endangered species listed by the International Union for Conservation of Nature (IUCN). I have pioneered collaborations with traditional harpoon fishermen and the operators of large set nets that catch a wide variety of highly migratory species. The bio-logging data got by smart electronic tags are used by the OCA for conservation planning and public education such as the International Shark Day press and social media content.
