Dr. Edy Setyawan is a National Geographic Explorer with a strong interest in the population dynamics and movement ecology of marine megafauna, especially elasmobranch. He uses multidisciplinary approach including photographic identification (photo ID), drones, network analyses, passive acoustic telemetry, satellite telemetry and network analysis to understand distribution, movement patterns of marine animals, habitat and population connectivity for conservation and to inform management.
He has been working on marine research and conservation in Indonesia for nearly 15 years, and focusing on elasmobranch, especially manta rays since 2013.
He has a PhD in Marine Science from the University of Auckland, New Zealand. His PhD research focuses on the spatial movement, habitat use, distribution, and population structure of reef manta rays (Mobula alfredi) in Raja Ampat archipelago, West Papua, Indonesia. Using long term database of reef manta ray photo ID, he evaluated the effectiveness of full protection on manta rays on the species in Raja Ampat.
He pioneered a non-invasive technique to measure the body size of manta rays accurately using small drones with minimal or no impact on the animals. Recently, he and his research team have just confirmed the existence of world's first reef manta ray nursery area in Wayag lagoon, Raja Ampat after 8 years of monitoring.
